How to Migrate Web Hosts Without Downtime (2026 Guide)
Copy everything, test the new server before anyone sees it, then flip DNS, a migration done in the right order loses zero visitors.
The zero-downtime principle
The trick to a painless migration is simple: your old site keeps running untouched while you build and verify a complete copy on the new host, and only then do you switch the address over. Done in that order, visitors never see an error page. Downtime happens when people delete first and copy second, or point DNS at a server that is not ready.
Step 1: Back up everything
Before touching anything, take a full backup of your files and your database, and download it somewhere off the old server. Export your email if it lives with the same host. This copy is your undo button; with it, no mistake later in the process is fatal. Skipping this step is how migrations turn into recovery jobs.
Step 2: Copy the site, or let the new host do it
Many hosts will handle the move for you. SiteGround includes one free professional migration with its plans, which means their team or migration tool transfers your files, database, and configuration while you watch. If you are moving to a host without that service, you upload your backup manually or use a migration plugin for WordPress sites.
Manual moves are less scary than they sound: upload your files, import the database, and update the configuration file with the new credentials. For WordPress specifically, a duplicator-style plugin packages all of that into a single archive and rebuilds it on the new server with a guided installer, which removes most of the fiddly steps.
Step 3: Test before anyone sees it
Preview the copy on the new server before DNS changes. Most hosts provide a temporary URL, or you can edit your computer's hosts file to load the new server under your real domain, a trick that shows the site exactly as visitors will get it. Click through key pages, test forms, log into the admin, and confirm HTTPS works with a valid certificate.
Step 4: The DNS cutover
A day before switching, lower the TTL on your domain's DNS records to 300 seconds so changes propagate quickly. Then update the records to point at the new host, nameservers or the A record, depending on your setup. Propagation typically completes within an hour at a low TTL. Keep the old account live for a week as a fallback before canceling.
Where to move
If you are choosing a destination, SiteGround pairs its free migration with the best support we have tested, a 47-second median first reply in our tickets, which is reassuring the first time you move a site. Hostinger is the value-and-speed pick at $2.99 per month, posting the fastest average load time of our test group at 456ms.
