If your priority is minimal downtime + an easy migration from shared hosting, I’d prioritize a provider with a good control panel/migration workflow rather than simply picking the cheapest VPS.

My shortlist

• Hostinger — easiest transition from typical shared hosting

• Probably my first choice if you're coming from cPanel/shared hosting and don't want to become a Linux sysadmin overnight.
• They have specific migration documentation for cPanel, DirectAdmin, CyberPanel, and shared hosting → VPS. Hostinger Help Center Hostinger Help Center
• Their VPS plans are relatively inexpensive and include things like snapshots, backups, and a web management interface. Hostinger
• Best for: WordPress, PHP/MySQL sites, several small websites, or anyone who wants a familiar hosting-style experience.
• DigitalOcean — best if you're comfortable with some server administration

• Excellent VPS/cloud experience and very good documentation.
• You get considerably more control than traditional shared hosting, but migration is more of a "build the new server, copy data, test, switch DNS" process rather than a magic migration button.
• Best for: Developers, Laravel/Node/Python apps, Docker, custom stacks, or if you expect to grow beyond conventional hosting.
• Vultr — similar to DigitalOcean

• Very quick VPS provisioning and lots of geographic locations.
• Good choice if you want straightforward cloud infrastructure without paying enterprise-cloud complexity.
• Best for: Technical users who want a clean VPS and don't mind doing the migration themselves.
• Hetzner — best price/performance

• Excellent value for the hardware, particularly if your audience is in Europe.
• I'd rank it below Hostinger/DigitalOcean specifically for your use case because migration simplicity matters more here than raw VPS value.
• Best for: Experienced Linux users who want maximum resources per dollar.
• Liquid Web — best if you want someone else to handle the hard parts

• More expensive, but managed VPS support makes it attractive when downtime or configuration mistakes would be costly.
• Current comparisons continue to position it toward businesses wanting hands-on managed VPS support. Hostinger
• Best for: Revenue-generating sites where paying more to avoid server administration is worthwhile.

What I'd choose

The migration strategy matters more than the provider

You can get essentially zero-downtime migration even when the provider doesn't have a fancy migration wizard.

I'd do it like this:

1. Lower your DNS TTL to something like 300 seconds a day or two before migration.
2. Build the VPS while the old shared host remains completely operational.
3. Copy your files and database to the VPS.
4. Test the new server using a temporary hostname or by overriding DNS locally.
5. Do a final database sync immediately before the cutover.
6. Change the DNS A record to the VPS.
7. Keep the old shared account running for at least 24–48 hours.
8. Only then cancel the old hosting.

For a database-driven site, the key is not copying everything once and immediately changing DNS. Keep the old site live, do your initial migration, then perform a final sync immediately before the DNS switch.

Hostinger's own migration documentation recommends this general approach and specifically notes using low-traffic periods and allowing for DNS propagation. Hostinger Help Center Hostinger

If you tell me your current shared host (e.g. Bluehost, HostGator, SiteGround, GoDaddy, cPanel, etc.), what you're running (WordPress/PHP/Laravel/etc.), and roughly how many sites/databases you have, I can narrow this down to 2–3 providers and give you the lowest-downtime migration path.
