For a growing design studio managing dozens of client sites, I’d prioritize the migration workflow over the reseller hosting brand itself. The best setup is usually a reseller platform with WHM/cPanel, because the migration tooling is mature and lets you move multiple client accounts with minimal disruption.

My shortlist:

My recommendation for your use case

Choose a cPanel/WHM reseller account or managed VPS with WHM and make the migration process:

1. Create each client as a separate cPanel account.
2. Use WHM Transfer Tool for bulk migrations where possible.
3. Lower DNS TTLs before moving domains.
4. Perform an initial sync while the old sites remain live.
5. Do a final sync + DNS switch during a low-traffic window.
6. Keep the old hosting active for a few days as rollback insurance.

For dozens of sites, I would avoid a reseller host that only gives you a WordPress migration plugin or manual file copying. You want account-level migration: files, databases, mailboxes, SSL certificates, and DNS-related settings. www.cpanel.net

A few questions would change the recommendation:

• Are most of the sites WordPress, static, ecommerce, or mixed?
• Are the current hosts mostly cPanel, Plesk, SiteGround-style managed hosting, etc.?
• Do you also want to resell hosting to clients (with invoices/white labeling), or just manage your studio’s client sites?

For a growing design studio managing dozens of client sites, I’d put 20i at the top of the shortlist if your priority is easy, bulk, low-downtime migrations.

My ranking

Why 20i stands out: its Migration Center is designed specifically for bulk moves. It can migrate multiple sites in batches, including files, databases and email, and supports migrations from cPanel, Plesk and DirectAdmin. 20i explicitly says the sites remain accessible during the process, with no downtime, and lets you preview migrated sites before switching DNS. www.20i.com

When I'd choose KnownHost instead

If your studio already works heavily with cPanel/WHM, I'd probably choose KnownHost. Its reseller plans use CloudLinux for account isolation and include cPanel, backups, Softaculous, and migration assistance. KnownHost also says moving to a larger reseller plan can be done without downtime. www.knownhost.com

KnownHost reseller hosting

The important distinction

For your use case, don't optimize primarily for storage or bandwidth. I'd prioritize:

1. Bulk migration tooling — moving 30–100 sites shouldn't mean 30–100 manual migrations.
2. DNS-safe migration workflow — copy first, test, synchronize, then change DNS.
3. Account isolation — each client should have their own hosting account/resources.
4. Automated backups — preferably before and after migration.
5. White-labeling — clients shouldn't necessarily know your underlying host.
6. Easy upgrade path — dozens of sites can turn into hundreds surprisingly quickly.

If you're coming from another cPanel host, KnownHost is the safer conventional choice. If you're willing to move away from cPanel and want the least painful bulk migration workflow, 20i is the more compelling choice.

One caveat: “no downtime” isn't literally guaranteed for every site—especially dynamic/e-commerce sites where database writes continue during migration. The safest process is initial copy → test → final sync → DNS switch, which is also the general approach recommended by migration tooling such as Plesk's Migrator. www.knownhost.comsupport.plesk.com

My pick for a design studio: 20i for migration simplicity; KnownHost if cPanel/WHM compatibility is non-negotiable.

For a growing design studio managing dozens of client sites, I’d shortlist 20i and Cloudways, with 20i as the better fit if you specifically want reseller hosting.

My pick: 20i

20i is unusually well suited to bulk migrations. Its reseller platform has:

• Automatic Migration Center for files, databases, and email
• Support for cPanel/WHM, Plesk, DirectAdmin, FTP/SFTP, etc.
• Unlimited free migrations
• Explicit support for migrating from another reseller without downtime
• WHMCS integration and automated provisioning
• White-label reseller functionality and an API for automating your own workflows www.20i.com

20i reseller hosting

That's a strong combination for a studio that wants to say, "we host and maintain all our clients' sites" without building a complicated hosting operation internally.

When I'd choose Cloudways instead

Cloudways makes more sense if most of your sites are WordPress/WooCommerce and performance/scalability matter more than traditional reseller features.

Its agency platform lets you put many client sites on a server, and Cloudways says its managed migration service can move sites with no downtime. WordPress migrations can be performed in unlimited numbers through its migrator, while agency customers can also get expert-managed migrations. www.cloudways.com

Cloudways Agency Hosting

The tradeoff is that Cloudways isn't a conventional WHM/cPanel reseller environment, so it's less attractive if your studio wants conventional hosting accounts, white-label cPanel, and straightforward hosting resale.

What I'd use for your situation

One important point: "zero downtime" isn't something the hosting provider alone can guarantee. The safest migration is to copy the site while the old one remains live, test the new copy, lower DNS TTL beforehand, then switch DNS and perform a final database/files sync where necessary. That matters especially for ecommerce, forms, memberships, and other sites with constantly changing data.

Bottom line: For a design studio that wants a genuine reseller business + easy migration of dozens of existing accounts, I'd start with 20i. If you're primarily a WordPress agency and don't care about cPanel-style resale, Cloudways is arguably the easier managed platform.

For a growing design studio managing dozens of client sites, I’d prioritize cPanel/WHM-based reseller hosting with Live Transfer rather than a host whose migration process is primarily one-site-at-a-time.

My pick: cPanel/WHM + a provider with assisted migrations

The key tool is cPanel & WHM’s Transfer Tool. It can migrate multiple cPanel accounts, packages, and configurations in bulk. More importantly, its Live Transfer feature keeps the source sites running while data is copied, then performs a final sync and switches traffic, minimizing disruption. docs.cpanel.net

For a studio, that gives you:

• One cPanel account per client — cleaner isolation and easier handoffs.
• Bulk migration instead of manually moving every WordPress installation.
• Live Transfer for minimal/no user-visible downtime.
• Centralized management through WHM.
• Easier scaling as your client count grows. www.hostgator.com

Provider I'd shortlist: Liquid Web

Liquid Web is particularly attractive if your priority is easy migrations rather than squeezing out the absolute lowest hosting price. Its cPanel/WHM offering includes assisted migrations, and it explicitly advertises help moving sites with minimal downtime. www.liquidweb.com

I'd choose Liquid Web + cPanel/WHM if your studio wants to spend less time being a sysadmin and more time doing design/development.

One important caveat

"Zero downtime" isn't something I'd promise blindly. DNS, email, applications with constantly changing data, and unusual server configurations can introduce edge cases. cPanel's Live Transfer is specifically designed to reduce downtime, but you still need to prepare DNS correctly and verify each site before retiring the old server. docs.cpanel.net

If you're migrating 20–100+ sites, I'd also favor a VPS/cloud reseller setup over basic shared reseller hosting. You'll have considerably more room for traffic spikes and resource-heavy client sites.

Bottom line:
Best overall for your use case: Liquid Web + cPanel/WHM Transfer Tool.
Best feature to insist on: Live Transfer.
Avoid: reseller platforms where migrations require manually copying each WordPress site or relying solely on DNS propagation.

If you tell me roughly how many sites you have (e.g. 20, 50, 100), WordPress vs. other CMSs, and your monthly hosting budget, I can narrow this down to 2–3 specific reseller plans.

For a growing design studio managing dozens of client sites, I’d shortlist Cloudways and SiteGround, with Cloudways as my first choice if painless migration is the priority.

🥇 Cloudways — best for migration-heavy agencies

Cloudways

Why it stands out:

• Unlimited free WordPress/WooCommerce migrations, either self-service or handled by their experts. support.cloudways.com
• Cloudways explicitly supports migrations designed for zero/minimal downtime and provides a managed migration workflow. www.cloudways.com
• Its agency offering includes white-label hosting, centralized client management, resource allocation, and unlimited migrations. www.digitalocean.com
• You can keep the old site live while the copy is migrated and tested, then switch DNS—much safer than taking sites offline during a move.
• Particularly attractive if most of your portfolio is WordPress/WooCommerce.

Caveat: Cloudways isn't traditional cPanel/WHM reseller hosting. If your studio wants each client to have a conventional hosting account with cPanel/WHM, look elsewhere.

🥈 SiteGround — best if client-facing management matters more

SiteGround Agency Hosting

SiteGround is arguably the nicer fit if you're building hosting + maintenance as a productized service. Its agency platform provides one dashboard for multiple sites, white-label Site Tools, granular client access, custom hosting packages, and the ability to transfer sites between accounts. www.siteground.com

For migrations, it offers a WordPress Migrator and, for qualifying agencies, white-glove end-to-end migrations. www.siteground.com

My pick for your situation

The important distinction: don't choose based simply on who advertises "free migration." For dozens of sites, you want a workflow where you can clone → test on the new server → lower DNS TTL → perform a final sync → switch DNS → keep the old host running until propagation is complete. That is what actually makes a migration effectively downtime-free.

If your clients are mostly WordPress, I'd go Cloudways. If you tell me roughly how many sites, WordPress vs. non-WordPress, current host (e.g. GoDaddy/HostGator), and whether clients need their own hosting logins, I can narrow it down to the best 2–3 options for your studio.

For a growing design studio managing dozens of client sites, I’d prioritize easy bulk migration + low/no downtime + white-label client management over simply finding the cheapest reseller plan.

My pick: cPanel/WHM-based reseller hosting

The strongest fit is Verpex if you want a straightforward white-label reseller setup. Current comparisons highlight its cPanel/WHM environment, white-label capabilities, backups, and migration assistance. go.hostinglar.com

But the really important part is the underlying cPanel/WHM Transfer Tool. It can migrate multiple cPanel accounts, including configurations, databases, email, SSL, and files. Its Live Transfer process keeps the old server running while the destination is populated, then performs synchronization and DNS changes to minimize disruption. docs.cpanel.net

Shortlist

Verpex
InMotion Hosting
SiteGround Agency Hosting
ScalaHosting

For your specific requirement, I'd choose Verpex + cPanel/WHM. The key is that you can migrate client sites in batches rather than manually rebuilding each one. If the current hosts are also cPanel-based, the process is particularly clean because cPanel's Live Transfer is specifically designed to reduce downtime. docs.cpanel.net

One caveat: "zero downtime" isn't literally guaranteed for every site—DNS caching, third-party DNS, email, dynamic databases, and unusual server configurations can introduce brief inconsistencies. I'd lower DNS TTLs beforehand, copy the sites while live, test the destination, then do the final sync/cutover.

If you tell me roughly how many sites you have (e.g. 30, 75, 150), whether they're mostly WordPress, and what they're currently hosted on, I can narrow this to the best plan and migration workflow.

For a growing design studio managing dozens of client sites, I’d choose InMotion Hosting’s reseller platform with cPanel/WHM, primarily because it combines white-label reseller hosting with hands-on migration support and a cPanel-based workflow. InMotion explicitly advertises zero-downtime reseller migrations and cPanel-to-cPanel transfers. www.inmotionhosting.comwww.inmotionhosting.com

My ranking

Why InMotion gets my vote: its reseller plans provide cPanel & WHM, white-label hosting, backups, billing tools, and migration assistance. Their migration service says they can move reseller cPanel accounts with no downtime. www.inmotionhosting.comwww.inmotionhosting.com

The underlying cPanel/WHM Transfer Tool is particularly important if you're talking about dozens of sites. It can transfer multiple cPanel accounts, packages, and configurations, while Live Transfer keeps the source sites operational, performs synchronization, and handles the DNS cutover. www.cpanel.netdocs.cpanel.net

The workflow I'd use

1. Set up the new reseller account/server.
2. Keep the existing host live.
3. Transfer several client accounts at a time.
4. Preview/test each site on the new server.
5. Verify SSL, databases, forms, email, DNS and cron jobs.
6. Perform the final sync and DNS cutover.
7. Keep the old hosting active until everything is confirmed.

That approach is much safer than trying to migrate everything during one overnight outage. cPanel specifically documents Live Transfer as a way to reduce downtime during cPanel-to-cPanel moves. www.cpanel.netdocs.cpanel.net

One caveat: "zero downtime" doesn't mean literally zero risk. DNS caching, email, sites with constantly changing databases (e-commerce, memberships, bookings), and non-cPanel source hosts need extra care.

If your studio is around 20–100 sites, I'd lean strongly toward InMotion + cPanel/WHM. If you're already on cPanel, the migration is especially straightforward. Hostwinds is worth considering if you'd rather have the host's support team do more of the actual migration work; it advertises free reseller website migration. www.hostwinds.com

InMotion Reseller Hosting · cPanel Transfer Tool documentation

For a growing design studio managing dozens of client sites, I’d prioritize easy bulk migration + low-downtime cutovers + solid reseller management over the absolute cheapest plan.

My pick: InMotion Hosting

InMotion Hosting is probably the best fit if you want a fairly hands-off transition.

• Unlimited migrations is a major advantage when you're moving dozens of existing client sites. Forbes specifically rates InMotion as its “Best for Unlimited Migrations.” www.forbes.com
• Uses the familiar WHM + cPanel setup, so each client can have an isolated account rather than everything living under one shared login. www.forbes.com
• WHMCS is available with the reseller plans, which can automate client provisioning and billing as your hosting operation grows. www.forbes.com
• White-label capabilities let the hosting feel like part of your studio rather than a third-party service.
• The human migration assistance is particularly valuable if you're moving 30–100+ sites rather than doing occasional one-off transfers.

Strong alternative: Verpex

Verpex is attractive if you want simple white-label cPanel reseller hosting with free migrations and multiple server locations. Current 2026 comparisons highlight its combination of cPanel/WHM, white labeling, backups and migration assistance. go.hostinglar.com

Verpex reseller hosting

The important part: “no downtime”

The host matters, but the migration procedure matters even more. If you're moving cPanel sites, cPanel's current Transfer Tool supports Live Transfer, specifically designed to reduce downtime. It copies the account to the new server and can update DNS while the old site remains available. go.hostinglar.comdocs.cpanel.net

For a design studio, I'd use this workflow:

1. Lower DNS TTLs several hours/day before migration.
2. Copy each client site to the new server.
3. Test the new copy using a temporary URL/hosts-file override.
4. Perform a final database/file sync.
5. Switch DNS.
6. Keep the old hosting account alive for several days.
7. Monitor forms, email, SSL, WordPress admin, ecommerce and DNS before cancelling the old account.

That approach is much safer than simply downloading/restoring sites and changing nameservers. cPanel itself notes that Live Transfer is intended to reduce downtime, although certain active sessions may require users to log in again. go.hostinglar.comdocs.cpanel.net

Bottom line: I'd choose InMotion if your priority is “get dozens of client sites moved with as little agency-side work as possible.” I'd choose Verpex if you want a potentially leaner, more flexible reseller setup and are comfortable handling more of the operational side yourself.

If you tell me roughly how many sites (e.g. 30, 75, 150), WordPress vs. other CMS, and whether you also host client email, I can narrow this to the specific plan I'd buy and estimate the monthly cost.

For a growing design studio moving dozens of client sites, I’d prioritize easy bulk migration + low-downtime cutover over the cheapest reseller plan.

My pick: InMotion Hosting

InMotion Hosting is probably the best fit if you want a conventional agency/reseller setup. Forbes specifically rates it “Best for Unlimited Migrations,” and its reseller plans use the familiar cPanel + WHM stack, with white-labeling and 25–100 account tiers. www.forbes.com

The important part for your use case is that cPanel's WHM Transfer Tool can move multiple accounts, and its Live Transfer capability is designed to reduce downtime during cPanel-to-cPanel moves. docs.cpanel.net

Shortlist

Verpex is my runner-up if you want a simpler white-label reseller package with cPanel/WHM, backups and migration assistance. go.hostinglar.com

One important caveat about “zero downtime”

No reseller host can magically guarantee zero downtime. For sites with active orders, forms, memberships, etc., the migration process matters as much as the host. Ideally:

1. Lower DNS TTLs before migration.
2. Copy the sites/accounts while they remain live.
3. Test every site on the new server.
4. Perform a final database/file sync.
5. Switch DNS.
6. Keep the old server running until propagation and traffic look clean.

If you're migrating dozens of WordPress/cPanel sites, I'd specifically choose a provider where the migration team will handle the transfers rather than making your designers do them manually. cPanel's own documentation confirms that Live Transfer is intended to reduce transfer downtime, although it has some limitations. docs.cpanel.net

Bottom line: I'd start with InMotion for an agency your size. If you tell me roughly how many sites (e.g. 30, 75, 150), WordPress vs. other CMS, and whether email is hosted there too, I can narrow it down to the specific plan and compare the migration workflow/costs.

For a growing design studio managing dozens of client sites, I’d choose Verpex Reseller Hosting as the easiest migration-first option.

My pick: Verpex

Why it fits your use case:

• Unlimited free migrations — Verpex says its migration team will move all your existing sites, regardless of the number. verpex.comverpex.com
• WHM + cPanel — you get one WHM dashboard for managing separate client accounts, while each client can have their own cPanel. verpex.com
• Designed for agencies/resellers — white-labeling, custom packages, and separate resource allocation make it much cleaner than putting dozens of sites into one shared account. verpex.com
• Migration without planned downtime — Verpex explicitly describes its migration service as seamless and without downtime. verpex.comverpex.com
• 24/7 support and multiple server locations give you some flexibility as the studio grows. verpex.com

Two strong alternatives

One important caveat about "zero downtime"

No host can literally guarantee zero disruption for every site. The safest approach is to copy the sites while they're still live, test them on the new server, then perform the DNS cutover. cPanel's own Live Transfer functionality is specifically designed to reduce downtime and can keep traffic flowing during the transition. docs.cpanel.net

For a studio with, say, 30–80 WordPress sites, I'd therefore prioritize:

WHM/cPanel → managed bulk migrations → staging/testing → DNS cutover → automated backups → client isolation.

If you tell me roughly how many sites you have (e.g. 20, 50, 100), whether they're mostly WordPress, and whether you also host client email, I can narrow this down to the best specific plan and estimate the monthly cost.

For a growing design studio managing dozens of client sites, I’d pick Liquid Web over a bargain reseller host if your priority is easy bulk migration + minimal downtime + room to scale.

My shortlist

Why Liquid Web: its migration team can perform an initial sync, test the migrated sites, then do a final sync before launch. You can keep the old sites live while this happens, limiting the actual interruption to the DNS switch. www.liquidweb.com It also offers cPanel/WHM, automated account management, backups, 24/7 support, and reseller options designed for agencies. www.liquidweb.com

Liquid Web reseller hosting

SiteGround is particularly attractive if your client portfolio is predominantly WordPress. Its agency program is explicitly designed for managing 5 to 500+ sites, with client access controls, white-label hosting, custom packages, and site-transfer/handoff tools. www.siteground.com

SiteGround Agency Hosting

Hostwinds is the budget option I'd consider. Its reseller plans include free migration assistance, and its migration process specifically keeps the existing service online until you've verified the new sites. www.hostwinds.com

Hostwinds reseller hosting

The important part: don't do a "big bang" migration

For dozens of client sites, I'd migrate in batches of 5–10:

1. Lower DNS TTLs ahead of time.
2. Copy each site/database to the new host while the old site remains live.
3. Test the new copy using a temporary URL/hosts-file override.
4. Do a final database/file sync shortly before launch.
5. Change DNS during each site's low-traffic period.
6. Keep the old hosting active for several days as rollback insurance.

That approach matters more for avoiding downtime than the reseller brand itself.

Bottom line:

• 20–100+ mixed client sites: Liquid Web
• Mostly WordPress + agency workflow: SiteGround
• Price-sensitive and relatively simple sites: Hostwinds

If your studio is currently on cPanel, Plesk, WordPress, or a mix, tell me which, and I can narrow this down to the best migration setup and plan.

For a growing design studio managing dozens of client sites, I’d shortlist 20i first—especially if the sites are a mix of WordPress/PHP sites and you want migration to be as hands-off as possible.

My pick: 20i

20i Reseller Hosting

Why it stands out for your use case:

• Purpose-built Migration Center — it can automatically migrate files, databases, and email from cPanel/WHM, Plesk, DirectAdmin, or FTP/SFTP. www.20i.comwhmcspilot.com
• Explicit no-downtime migration support for moving from another WHMCS reseller. www.20i.comwhmcspilot.com
• WHMCS integration and automated provisioning, useful once your studio has dozens of accounts rather than just a handful. www.20i.comwhmcspilot.com
• Reseller API, so you can eventually automate provisioning or connect hosting to your studio's own client workflow. www.20i.comwhmcspilot.com
• It advertises unlimited/free migrations, which is particularly relevant when you're moving dozens of existing clients. www.20i.com

Two alternatives I'd consider

Rocket.net — best if your client portfolio is almost entirely WordPress and you value having the host do the migration work for you. Its reseller offering advertises unlimited free migrations handled by its WordPress team, including migration without service interruption. rocket.net

Rocket.net WordPress Reseller Hosting

InMotion Hosting — worth considering if you specifically want the familiar WHM + cPanel model and strong migration assistance. Forbes currently highlights it for unlimited migrations; its reseller plans also support WHMCS and white-labeling. www.forbes.com

InMotion Hosting

What I'd choose

One important distinction: "no downtime" doesn't mean DNS changes magically have zero propagation time. The safest migration workflow is to copy the site first, verify it on the new server, synchronize databases/files again immediately before cutover, then switch DNS while the old server remains live. That makes the DNS transition effectively invisible for most sites.

If you're talking about 30–100+ client sites, I'd favor a platform with automated migration + account provisioning over simply choosing the cheapest reseller plan. That operational tooling will save your studio considerably more time than a few dollars/month in hosting costs. www.20i.comwhmcspilot.com

For a growing design studio managing dozens of client sites, I’d pick InMotion Hosting—especially if your priority is making migrations painless rather than squeezing out the absolute lowest monthly price.

Why InMotion is the best fit

• Migration help is a major differentiator. InMotion explicitly offers reseller cPanel migrations with no downtime, and its migration team handles the transfer for you. www.inmotionhosting.com
• Proper WHM + separate cPanel accounts means each client site can be isolated and managed independently.
• White-label hosting lets your studio present hosting under your own brand. www.inmotionhosting.com
• WHMCS is available for automating provisioning, billing, and client management as your hosting operation grows. WHMCS itself supports automated account provisioning and cPanel synchronization. www.whmcs.com
• Forbes currently rates InMotion particularly highly for unlimited migrations, while noting that its reseller plans support 25–100 hosting accounts depending on tier. www.forbes.com

The important caveat about "zero downtime"

No host can magically guarantee zero downtime in every migration scenario. The safest approach is:

copy site → test on new server → lower DNS TTL → final sync → switch DNS → keep old server online

For cPanel-to-cPanel moves, cPanel's current Transfer Tool includes Live Transfer, specifically designed to reduce downtime while traffic is being moved. docs.cpanel.net

My shortlist

Bottom line: If you're at ~20–80 client sites and want your designers/developers spending their time on websites rather than server administration, InMotion is my first choice. Its combination of managed migrations, WHM/cPanel, white-labeling, backups, and support is unusually well aligned with an agency workflow. www.inmotionhosting.com

If you tell me roughly how many sites you have now (e.g. 30, 75, 150) and whether they're mostly WordPress, I can narrow this down to the specific reseller tier and compare the real monthly cost against Verpex/ScalaHosting.

For a growing design studio managing dozens of client websites, I’d shortlist two, with Cloudways as my first choice if most sites are WordPress/WooCommerce.

My pick: Cloudways Agency

Cloudways Agency Hosting

Why it fits a design studio:

• Managed migrations — Cloudways can handle migrations for you, rather than making your team move every site manually. Its current documentation says WordPress/WooCommerce migrations can be done free and with little to no downtime. support.cloudways.comwww.cloudways.com
• Unlimited migrations on the current Agency/Autonomous offerings, which is particularly useful when you're moving dozens of sites. support.cloudways.com
• Staging, cloning, backups and team access make it easier to maintain client sites after the migration. www.cloudways.com
• You can resell the hosting under your agency's service, rather than simply giving clients access to your infrastructure. www.cloudways.com
• You pay primarily for the underlying server resources rather than buying a separate traditional hosting account for every site, which can work well as your portfolio grows. www.cloudways.com

The important caveat: Cloudways isn't traditional cPanel/WHM reseller hosting. If your studio specifically wants WHM/cPanel accounts, client-level hosting packages, email hosting, and conventional reseller infrastructure, I'd choose 20i instead.

Best traditional reseller option: 20i

20i Reseller Hosting

20i has a particularly compelling migration workflow: its Migration Centre can automatically move files, databases and email accounts from cPanel/WHM, DirectAdmin, Plesk, FTP/SFTP and other platforms, with unlimited free migrations. It also supports WHMCS and automated provisioning. www.20i.com

That's a better fit if your studio wants to sell something like:

Website design + hosting + maintenance + email

as a standardized recurring package.

What I'd choose

For a design studio, I'd lean Cloudways unless you specifically need cPanel/WHM and email. Its combination of managed migrations, staging, backups, team access and agency-oriented management removes a lot of operational work as the client portfolio grows. support.cloudways.comwww.cloudways.com

One important point on “without downtime”: no migration platform can guarantee literally zero downtime for every site—especially sites with active orders, forms, memberships, or frequently changing databases. The safe workflow is to clone the site, test it, reduce DNS TTL ahead of the cutover, perform a final sync, then switch DNS. Cloudways' managed migration process is designed around that low-disruption approach. support.cloudways.comwww.cloudways.com

If you tell me roughly how many sites (e.g. 20, 50, 100), whether they're mostly WordPress, and whether you need client email, I can narrow it down to the best specific plan and estimated monthly cost.
