If your priorities are full data ownership + a migration that doesn't become a giant engineering project, I’d shortlist these:

My default recommendation: WooCommerce

WooCommerce is probably the least painful transition from a hosted platform if you want to own the infrastructure and database.

WooCommerce stores product data directly in your WordPress database, and its tooling supports CSV import/export. There are also migration tools for customers, orders, coupons, reviews, and subscriptions. WooCommerce WooCommerce

The big advantage is that you aren't locked into a proprietary data store: you control the WordPress/WooCommerce database, filesystem, hosting, backups, and code.

When I'd choose Shopware instead

Shopware is particularly compelling if you're running a larger catalog, multiple storefronts, B2B, multiple languages/currencies, or a more sophisticated commerce operation.

Its Migration Assistant is specifically designed for moving data from another ecommerce system and can migrate things such as products, manufacturers, and customers. It performs data checks and provides mappings for data that doesn't line up cleanly between systems. Shopware Docs Shopware Store

That's a meaningful advantage over simply dumping CSVs into a new store.

docs.shopware.com

What I'd avoid unless you have a specific reason

Magento Open Source gives enormous control, but I'd only pick it if you actually need Magento's enterprise-level architecture. The migration and ongoing infrastructure burden is substantially higher.

Medusa is excellent if you have developers and specifically want a headless, API-first architecture. But if your goal is "make this migration manageable," it generally isn't my first choice—you'll be taking on considerably more implementation work.

The important question is your current platform

The best choice depends heavily on what you're migrating from. Shopify → WooCommerce is a very different project from Salesforce Commerce Cloud → Shopware, for example.

If you tell me your current hosted platform, approximate number of products/orders, and whether you need to preserve customer accounts/order history, I can recommend the best target and lay out a practical migration path.

If your priorities are self-hosting, full data ownership, and making the migration as painless as possible, I’d shortlist WooCommerce and Shopware 6.

My ranking

I'd pick WooCommerce if minimizing migration pain is the priority. Your products live in your own WordPress database, and WooCommerce has built-in product CSV import/export. Its ecosystem also has tooling for migrating customers and orders, including field mapping. woocommerce.com

WooCommerce migration documentation

I'd pick Shopware 6 if you're moving from a substantial hosted store and want a more dedicated ecommerce platform. Its Migration Assistant is specifically designed to transfer things such as products, manufacturers, customers and other datasets, performs data checks, and supports mappings when source and destination structures don't line up. It can also migrate from cloud to self-hosted. docs.shopware.com

Shopware migration documentation

One important distinction

If by "full control over data" you mean I want the database, files, backups, and infrastructure under my control, both WooCommerce and Shopware fit.

If you also mean I don't want to be locked into the platform's data model, I'd lean WooCommerce. Its WordPress-based storage and CSV/XML tooling make it relatively straightforward to extract and transform data independently of the platform. woocommerce.com

For a highly technical team, Medusa is worth considering too: its migration tooling is explicitly designed to map data from Shopify, WooCommerce, Magento and other platforms into its own models, and migrations can be rerun. It's much more of a developer-oriented/headless approach, though. docs.medusajs.com

If you tell me what hosted platform you're migrating from (Shopify, BigCommerce, Wix, Squarespace, etc.), plus roughly how many products/orders you have, I can tell you which of these would make the migration easiest and what data is likely to be painful to transfer.

If your priority is full data ownership and a manageable migration from a hosted ecommerce platform, I’d usually shortlist these:

1. WooCommerce — easiest migration path for many merchants

Best if you want the least disruption.

Good fit when:

• You already have a content-heavy site or use WordPress
• Your catalog is small-to-medium
• You want lots of extensions and developers available
• You want direct access to your database, files, and hosting

Migration advantages:

• Many import tools exist for products, customers, orders, coupons, and reviews
• Familiar admin experience for non-technical teams
• Easy to export your data because it lives in your own database

Trade-offs:

• Large catalogs and complex workflows may require careful database tuning
• Heavy reliance on plugins can create maintenance overhead Datafirefly SwingIntel

2. PrestaShop — a strong middle ground

Best if you want a dedicated ecommerce application rather than building on a CMS.

Good fit when:

• You sell internationally
• You need multiple languages/currencies
• You want a standalone store platform
• You want ownership without Magento-level complexity

Migration advantages:

• Purpose-built catalog, checkout, inventory, and order systems
• Data model is more ecommerce-focused than WooCommerce
• Good balance between flexibility and operational complexity Velocity AI Railway

Trade-offs:

• Module quality varies, so extensions need careful evaluation
• You’ll manage hosting, updates, backups, and security

3. Adobe Commerce (Magento Open Source) — for complex businesses

Best if you need enterprise capabilities.

Good fit when:

• You have large catalogs
• You need advanced pricing rules, B2B features, multiple stores, or complex integrations
• You have developers or an agency budget

Migration advantages:

• Extremely flexible data model
• Handles complex commerce logic well

Trade-offs:

• Migration is usually a larger engineering project
• Hosting and maintenance requirements are significantly higher SwingIntel

4. API-first options (for technical teams)

Platforms such as Medusa or Saleor can give maximum control, especially if you want a custom frontend, but migrations are usually less “lift and shift” and more of a rebuild. Open Source Groups

My practical recommendation

For a hosted-to-self-hosted migration:

• Small business / DTC store: WooCommerce
• Growing brand wanting a real ecommerce engine: PrestaShop
• Large catalog, B2B, complex operations: Magento Open Source
• Engineering-led company wanting total architectural control: Medusa/Saleor

Before choosing, I’d audit your current platform export and confirm you can migrate:

• Product variants and attributes
• Customer accounts (including password migration limitations)
• Historical orders
• Reviews
• SEO URLs and redirects
• Tax/shipping rules
• Payment gateway data (usually cannot be transferred directly)

A “manageable” migration is often less about the platform itself and more about how cleanly it can preserve your existing data model and URLs. shopping-cart-migration.com

If you tell me your current hosted platform (Shopify, BigCommerce, Wix, Squarespace, etc.), catalog size, and whether you sell B2B or DTC, I can narrow this down.

If your priority is full ownership of the data while keeping migration manageable, I’d shortlist WooCommerce, Shopware 6, and PrestaShop.

My ranking for migration ease

I'd pick WooCommerce for the least painful migration. Its products live in your WordPress database, and WooCommerce provides built-in CSV import/export plus documented approaches for migrating products and entire sites. woocommerce.com

Shopware 6 is my choice if you're coming from a more sophisticated hosted platform. Its Migration Assistant can transfer products, customers, orders, media, categories, SEO URLs, settings and more, and it supports repeated migration runs with checksums. docs.shopware.com It also has native CSV import/export with dry-run validation, which is particularly useful for testing a migration before touching production data. docs.shopware.com

PrestaShop is a good middle ground, particularly if you need multilingual or multistore capabilities. Its own migration guidance emphasizes getting exports/database access from the existing provider before starting; without that access, some data may have to be recreated manually. help-center.prestashop.com

The important catch

"Self-hosted" doesn't automatically mean everything migrates cleanly. The difficult pieces are usually:

• customer accounts/passwords
• historical orders
• product variants
• subscriptions
• discounts/promotions
• reviews
• SEO URLs and redirects
• images/media
• custom fields
• integrations and payment history

So I'd choose based heavily on what your current hosted platform can export. If it gives you clean CSV/API/database exports, the migration becomes dramatically easier.

Rule of thumb:

• Under ~10k products and relatively straightforward store → WooCommerce
• Complex catalog/B2B/multiple sales channels → Shopware 6
• Multilingual/multistore traditional ecommerce → PrestaShop

If you tell me which hosted platform you're migrating from (Shopify, BigCommerce, Wix, Squarespace, etc.) and roughly how many products/orders/customers you have, I can recommend the easiest target and lay out what will and won't migrate.

If your priority is full ownership of the data + a migration that doesn't become a custom-engineering project, I’d put Shopware 6 at the top of the list.

My shortlist

Why Shopware 6 stands out: its official Migration Assistant is specifically designed to bring over products, customers, orders, categories, media, reviews, promotions, SEO URLs and other store data. It supports iterative migrations, checks data mappings, keeps migration logs, and can recognize unchanged records so you can repeat the migration safely. docs.shopware.com

It also explicitly supports self-hosting on your own server or hosting provider, with local data storage and extensive customization. www.shopware.com

Shopware migration documentation

When I'd choose the others

• WooCommerce — probably the easiest choice if your store is relatively straightforward and you're already using WordPress. Product data lives in your WordPress database, giving you direct ownership and database-level control. woocommerce.com
• Medusa — excellent if you have developers and want the commerce backend to be a composable building block rather than a conventional all-in-one storefront. It also supports straightforward product CSV exports. docs.medusajs.com
• Magento Open Source — powerful for complex catalogs, B2B, multiple stores and sophisticated pricing, but I'd avoid it if migration/manageability is your primary concern unless you already have Magento expertise.

My recommendation:
If you're coming from Shopify, BigCommerce, Wix, Squarespace Commerce, etc. and want to get away from hosted infrastructure without giving up a mature ecommerce system, Shopware 6 is probably the best balance of migration tooling, data ownership, and extensibility.

If you tell me what hosted platform you're migrating from, approximate number of products/orders/customers, and whether you have a developer, I can narrow this down to the best 1–2 options and explain exactly what will and won't migrate.

If your main goal is full control over data while keeping the migration from a hosted platform manageable, I’d usually shortlist these:

www.datafirefly.comwww.velsof.com

My practical recommendation

For the easiest migration with real ownership:
→ WooCommerce
Good choice if your current hosted store has fairly standard data:

• products
• variants
• customers
• orders
• coupons
• blog/content

You can keep your database, files, and hosting under your control. The WordPress ecosystem also gives you many migration tools and integrations. The downside is that you need discipline around plugins, updates, and performance tuning. www.datafirefly.comswingintel.com

For a cleaner “store-first” system:
→ PrestaShop
I’d consider this if you want ecommerce to be the center of the system rather than a WordPress site with commerce added. It has strong catalog management and multi-language capabilities. www.datafirefly.com

For a serious enterprise migration:
→ Magento Open Source
Choose this if you have:

• tens of thousands of SKUs
• complex pricing rules
• multiple warehouses
• B2B accounts
• custom workflows

It gives enormous control, but migration is more like a software project than a platform switch. www.velsof.com

Migration features I would prioritize

Regardless of platform, make sure you can export/import:

• Product IDs and SKUs (preserve them if possible)
• Variant relationships
• Customer accounts
• Order history
• Reviews
• SEO URLs and redirects
• Images/media
• Tax and shipping rules
• Discount codes
• Inventory history (if important)

A common mistake is moving only products and customers, then discovering years of order history and SEO value were lost.

A simple decision rule

• Under ~5,000 products + you want manageable operations: WooCommerce
• Need a dedicated ecommerce engine + international selling: PrestaShop
• Large catalog or complex business rules: Magento Open Source
• Developer-heavy custom storefront: Shopware or Medusa

swingintel.com

If you tell me what hosted platform you’re leaving (Shopify, BigCommerce, Wix, Squarespace, etc.), approximate product count, and whether you need subscriptions/B2B/multi-store, I can narrow this down.

If your priority is self-hosting + full data ownership + a manageable migration, I’d shortlist these:

My default recommendation: WooCommerce

If you're coming from a hosted platform such as Shopify, Wix, BigCommerce, Squarespace, etc., WooCommerce is probably the least painful transition.

It is open source and self-hostable, and your product data lives in your own WordPress database. WooCommerce also has documented migration paths and CSV import/export tooling. woocommerce.com

For a full migration, WooCommerce's tooling can handle customers, products, reviews, coupons, orders, and subscriptions, with mappings available for fields that don't line up cleanly between platforms. woocommerce.com

WooCommerce migration documentation

When I'd choose Shopware instead

If this is a substantial store with lots of customers/orders, multiple storefronts, B2B requirements, multiple languages/currencies, or complex business rules, I'd seriously consider Shopware 6.

Its Migration Assistant is specifically designed to transfer things like products, customers, categories, media and other store data, and it supports repeated migration runs so you can test and refine the process before going live. docs.shopware.com

That's a big advantage over choosing a platform where migration essentially means writing your own import pipeline.

Shopware Migration Assistant documentation

When not to pick WooCommerce

I'd lean toward Medusa or Saleor if you're intentionally moving away from a traditional monolithic ecommerce CMS and have developers who want an API-first/headless architecture. Both are designed to be self-hosted and highly customizable, but you're likely doing more application development rather than simply transferring a store. saleor.io

In short:

• Want the easiest migration: WooCommerce
• Want robust self-hosted commerce for a larger/complex business: Shopware
• Want a modern custom/headless stack: Medusa
• Want GraphQL + enterprise-grade composable commerce: Saleor

If you tell me what hosted platform you're migrating from (e.g. Shopify, BigCommerce, Wix) and roughly how many products/orders/customers you have, I can narrow this down considerably and tell you which platform will involve the least migration pain.

If your priorities are full data ownership + a manageable migration, I’d shortlist these:

My default recommendation: WooCommerce

WooCommerce is probably the least painful migration target if you're coming from a hosted platform and don't have unusually complex requirements.

It's open source, self-hostable, and WooCommerce explicitly emphasizes full ownership of the store and its data. Product data lives in your WordPress database, and there are documented mechanisms for importing/exporting products and migrating the entire database. woocommerce.com

The big advantage is the ecosystem: you're much more likely to find an importer, connector, or migration tool for your current platform rather than having to build the migration yourself.

When I'd choose Shopware instead

Shopware is the stronger choice if you're running a serious catalog, B2B operation, multiple sales channels/stores, or expect substantial customization.

Shopware supports self-hosting with local data storage and full control over the infrastructure. More importantly for your situation, it has a dedicated migration assistant and documentation covering migration of products, customers, orders, and other store data. www.shopware.com

So if your definition of "manageable" includes having the destination platform provide an actual migration framework, Shopware is particularly compelling.

One important distinction

Don't confuse "I can export my data" with "migration is easy."

The difficult parts are usually:

• customer accounts/passwords
• historical orders
• product variants/options
• categories and URLs
• discounts/promotions
• subscriptions
• tax/shipping rules
• images and media
• SEO redirects
• integrations and webhooks
• payment tokens

I'd therefore choose the platform based heavily on how closely its data model matches your current store, rather than simply picking the platform with the most features.

If you tell me what hosted platform you're migrating from (Shopify, BigCommerce, Squarespace, Wix, etc.), approximate SKU count, and whether you need B2B/multi-store/subscriptions, I can recommend the specific self-hosted platform and outline the lowest-risk migration path.

If your priority is full control over your data while keeping the migration manageable, I’d shortlist Shopware 6 and WooCommerce, with Shopware 6 as my first choice for a serious standalone store.

My pick: Shopware 6

Shopware is particularly attractive for migration because its Migration Assistant is designed specifically to move products, customers, orders, media, categories, reviews, promotions, SEO URLs and other data from an existing shop. docs.shopware.com

It can also run on your own server, so you're not giving up the data ownership you're trying to regain. Shopware explicitly supports migrating from cloud installations to self-hosted installations. docs.shopware.com

A useful feature for migration is that you can keep the source store running while doing subsequent migration passes, which makes it easier to stage the new store and perform a controlled cutover rather than doing everything in one risky operation. docs.shopware.com

When I'd choose WooCommerce instead

Choose WooCommerce if your store isn't particularly complex and you want the largest ecosystem and straightforward access to the underlying database. WooCommerce stores product data in your WordPress database and provides built-in CSV import/export as well as full database migration options. woocommerce.com

WooCommerce is probably the easiest migration destination for a relatively simple store. Shopware becomes more compelling as you have complex catalogs, multiple sales channels, B2B requirements, multiple languages, or substantial order/customer history.

One important caveat

"Self-hosted" doesn't automatically mean easy to migrate. The difficult part is usually not products—it is things like:

• customer accounts/passwords
• historical orders
• subscriptions
• discounts/promotions
• product variants
• images and media
• SEO URLs and redirects
• tax/shipping rules
• custom fields
• third-party integrations
• payment data/tokenization

I'd therefore choose the platform based on how well it can represent your existing data, not just how easy it is to install.

If you tell me what hosted platform you're migrating from (Shopify, BigCommerce, Wix, Squarespace, etc.), roughly how many products/orders you have, and whether you need subscriptions or B2B, I can narrow this down to the best migration path.

If your priority is full data ownership + a migration that doesn't become a major engineering project, I'd shortlist these:

My default recommendation: WooCommerce

If you're coming from a hosted platform such as Shopify, BigCommerce, Wix, Squarespace, etc., WooCommerce is probably the least painful migration.

Your store data lives in your own WordPress database, and WooCommerce provides built-in CSV import/export plus WordPress-level database/site migration options. woocommerce.com

The important advantage isn't just "self-hosted." It's that there's a huge ecosystem for importing products, customers, orders, URLs, reviews, subscriptions, etc. You can run it on your own VPS, managed server, or even your own infrastructure.

I'd choose it if you have:

• a conventional storefront
• hundreds to tens of thousands of products
• standard customer/order/catalog data
• a desire to minimize custom migration code
• a preference for a mature ecosystem

Shopware 6 is the stronger alternative

If your store is more complicated—multiple storefronts, countries/languages, sophisticated catalog rules, B2B, large product catalogs—I'd seriously consider Shopware 6.

Shopware explicitly supports self-hosting and local data storage. www.shopware.com More importantly for your situation, its Migration Assistant is designed to move products, customers, orders, media, categories, reviews, promotions, SEO URLs, settings, etc. from another commerce system. docs.shopware.com

It also has a useful iterative migration process: you can run migrations repeatedly, with checksums preventing unchanged data from being unnecessarily duplicated. docs.shopware.com

That makes Shopware particularly attractive if you're trying to make migration repeatable rather than a one-shot database surgery.

What I'd avoid for a straightforward migration

Medusa is excellent if your goal is an API-first, headless architecture and you have developers who want to own the entire application stack. But you're effectively building more of the commerce experience yourself. It's not my first choice if "make migration manageable" is the primary objective.

Magento Open Source gives you enormous control, but that control comes with substantial operational and development complexity. I'd only choose it if your business requirements actually justify it.

The key question

The best choice depends heavily on what you're migrating from.

For example, migrating:

Shopify → WooCommerce
is a very different project from:

Shopify → Shopware 6

and both are much easier than trying to preserve every bit of data from a heavily customized hosted system.

If you tell me which hosted platform you're leaving, approximate number of products/orders/customers, and whether you need subscriptions/B2B/multiple countries, I can recommend the best target and map out what data will and won't migrate cleanly.

If your priorities are self-hosting, full data ownership, and a migration that doesn’t become a custom-engineering project, I’d put Shopware 6 at the top of the shortlist.

My recommendation: Shopware 6

Shopware is particularly migration-friendly because it has a dedicated Migration Assistant, rather than making you build the migration entirely around generic CSV imports. Its documented migration process can transfer products, customers, orders, media, categories, reviews, promotions, SEO URLs, and other store data. docs.shopware.comdocs.shopware.com

It also supports running on your own server or hosting provider, with local data storage and substantial customization. www.shopware.com

The big caveat is that themes, some extension-specific data, payment configuration, and certain custom workflows generally require rebuilding or manual checking. docs.shopware.comdocs.shopware.com

How I'd compare the main choices

WooCommerce is arguably the easiest choice if your store isn't particularly complex. Its products live in your WordPress database, and it has built-in CSV import/export plus migration documentation. woocommerce.com

Medusa gives you a lot of architectural control, but I'd choose it when you specifically want a developer-oriented/headless stack rather than simply wanting an easier migration. Its documented product migration, for example, relies on CSV imports. docs.medusajs.com

The deciding factor

If you tell me what hosted platform you're migrating from (Shopify, BigCommerce, Wix, Squarespace, etc.) and roughly how many products/orders/customers you have, I can tell you which self-hosted option will make your specific migration easiest and what data you're likely to lose or have to rebuild.

If your main goal is full control over your data while keeping the migration from a hosted platform manageable, I’d usually shortlist these:

www.datafirefly.comswingintel.com

My default recommendation for a manageable migration

For most businesses leaving Shopify, BigCommerce, Wix, Squarespace, or another hosted platform, I’d start with WooCommerce:

• Familiar data model: products, customers, orders, coupons, media, pages.
• Large migration ecosystem and many import/export tools.
• You control the database, files, hosting, and integrations.
• Easier to find developers and maintain long term. swingintel.com

It’s especially attractive if your store also relies on content marketing, blogs, SEO, or editorial pages because it inherits WordPress’s ecosystem. www.datafirefly.com

Choose something else if:

• You have 50k+ products, complicated catalogs, wholesale pricing, multiple warehouses, or heavy B2B workflows: look at Magento Open Source / Adobe Commerce. It gives deeper commerce modeling but requires more engineering. www.datafirefly.comswingintel.com
• You sell internationally with many languages, currencies, and regional rules: PrestaShop is often a smoother fit. www.datafirefly.com
• You want a custom frontend (React/Next.js, mobile apps, multiple sales channels): consider Shopware or a headless platform. cozycommerce.dev

For a smooth migration, prioritize these regardless of platform:

1. Export and archive all source data from the hosted platform:
   • products/SKUs
   • customers
   • orders
   • refunds
   • reviews
   • images/files
   • SEO metadata
   • redirects
2. Preserve:
   • product IDs/SKUs where possible
   • customer history
   • URLs (or create 301 redirects)
   • structured product data
3. Test a full migration on a staging server before switching DNS.
4. Keep the old store available in read-only mode until orders and customer records are verified.

If you tell me what hosted platform you’re leaving, your catalog size (number of products), and whether you need B2B/multi-store/international sales, I can narrow this to one or two choices.

If your priorities are full data ownership + a manageable migration, I’d shortlist WooCommerce, Shopware, and PrestaShop, with WooCommerce as the easiest default for most small-to-mid-sized stores.

My pick: WooCommerce

WooCommerce stores its product data in your own WordPress database, and its built-in CSV/XML tooling makes importing and exporting relatively straightforward. WooCommerce also maintains migration guides for several hosted platforms. woocommerce.com

WooCommerce migration documentation

The big advantage is that you're not just moving to another hosted ecosystem—you control the database, files, hosting, backups, and code. The tradeoff is that you become responsible for security, updates, backups, and performance.

When I'd choose Shopware instead

If you have a large catalog, complex product structures, B2B requirements, or multiple storefronts, I'd seriously consider Shopware 6. Its Migration Assistant is specifically designed to transfer things such as products, manufacturers, customers and other datasets, and it supports self-hosted installations. docs.shopware.com

Shopware Migration Assistant documentation

It's more technically demanding than WooCommerce, but potentially a better long-term foundation for a sophisticated store.

PrestaShop

PrestaShop is another strong choice if multi-store or multilingual commerce is important. It is genuinely open source and self-hostable, but I'd put it slightly behind WooCommerce for migration simplicity unless its native commerce features specifically match your needs. PrestaShop itself recommends doing a requirements/specification exercise before migration because changing platforms isn't trivial. help-center.prestashop.com

One important point: the platform matters less than the quality of your migration plan. Before choosing, make an inventory of products/variants, customers, orders, passwords, reviews, coupons, images, URLs/SEO metadata, subscriptions, tax data, and integrations. Some of these—especially customer passwords and subscription/payment tokens—usually can't simply be copied between systems.

If you tell me what hosted platform you're migrating from (Shopify, BigCommerce, Wix, Squarespace, etc.) and roughly how many products/orders you have, I can recommend the least-painful target and migration path.

If your priorities are full data ownership + a manageable migration, I’d shortlist WooCommerce, Shopware, and PrestaShop rather than jumping straight to Magento/Adobe Commerce.

My pick: WooCommerce

WooCommerce is probably the easiest migration target for most small-to-mid-sized stores. Its product data lives in your WordPress database, and it has built-in CSV import/export plus established tools for moving products, customers, orders, reviews, subscriptions, and other data. woocommerce.com

Why I’d choose it:

• Self-hosted: you control the server, database, files, and backups.
• Migration-friendly: CSV/database-based import/export is mature.
• Huge ecosystem: easier to find migration plugins, developers, and integrations.
• Flexible: you aren't locked into a particular hosting provider.
• Lower operational complexity than Magento/Adobe Commerce.

The main downside is that WordPress/WooCommerce can become maintenance-heavy if you accumulate lots of plugins or have a very large/complex catalog.

If you're more technical: Shopware

Shopware is my choice if "full control" means you want a more purpose-built commerce system rather than WordPress.

Shopware Community Edition can be self-hosted on your own infrastructure, with local data storage and extensive customization. It also has a migration assistant specifically designed to bring over products, customers, orders, and other store data. www.shopware.com

It has particularly strong advantages if you need:

• large/complex catalogs
• multiple sales channels
• B2B
• multiple languages/stores
• headless/API-driven architecture
• a dedicated development team

Its tradeoff is more technical complexity than WooCommerce.

PrestaShop is another good middle ground

PrestaShop is worth considering if you're running a fairly traditional catalog-based store, particularly with international/multilingual requirements.

PrestaShop's own migration documentation explicitly covers importing categories, products, customers, order history, discounts, pages, and reviews, and recommends keeping the old store operational while validating the migration. help-center.prestashop.com

Quick decision

One important point: migrating away from a hosted platform is rarely a simple "export → import." The difficult parts are usually customer passwords, order history, product variants, URLs/SEO, subscriptions, discounts, tax rules, images, and custom fields. I'd select the destination platform partly based on how cleanly it can represent the data you already have.

If you tell me which hosted platform you're migrating from (Shopify, BigCommerce, Wix, Squarespace, etc.), approximate SKU count, and whether you need to preserve customer accounts/order history, I can narrow this down to the best option and outline the migration path.
