WordPress migration without downtime is achievable for almost any site, as long as the steps happen in the right order. The standard approach, export the database, transfer files, update config, switch DNS, creates a window of 24 to 48 hours where some visitors see the old site, some see the new one, and a misconfiguration shows an error to anyone caught in between. The order below removes that window entirely.
A WordPress migration without downtime works by keeping the old site fully live until the new site is confirmed working and DNS has fully propagated. At no point are visitors exposed to a broken site, because nothing changes for them until the new environment has already been tested and proven.
We regularly see migrations go wrong for one reason above all others: switching DNS before the new site has actually been tested. Everything else in this guide exists to prevent that single mistake.
The full WordPress migration without downtime process takes seven steps. Skipping the order, particularly testing before switching DNS, is where almost every migration-related outage actually comes from.
Before touching anything, create a complete backup of all files and the database, and store it locally on your computer. This is your safety net if anything goes wrong later.
Create your new hosting account and a fresh WordPress install. Don’t point your domain there yet. Access it via the server’s temporary URL or a staging subdomain for now.
Log into your domain registrar and lower the TTL on your A record to 300 seconds (5 minutes). This must happen 24 hours in advance, since the change itself takes that long to propagate. A low TTL is what makes the actual switch later take minutes instead of hours.
Using Duplicator or UpdraftPlus, create a complete package of your site, all files and the database in a single archive, and run the installer on the new host. The premium version makes this step a direct transfer; the free version works too, it just requires separating and restoring files and database manually. Your site is now running on the new host via the staging URL while the live site continues running normally on the old host.
Confirm the homepage loads correctly, navigation works on every page, the contact form submits and its notification email actually arrives, images load throughout, SSL is active on the staging URL, the PageSpeed score matches or beats the old site, and the mobile layout holds up across multiple screen sizes.
Once the new site is fully confirmed working, update the A record at your DNS provider to point to the new server’s IP address. Because the TTL was lowered in step three, this propagates globally within 5 to 15 minutes for most visitors. Keep the old hosting account active for at least 48 hours after switching.
Check the new site from multiple devices and networks, and watch your uptime tool over the following 48 hours. Once that window passes cleanly, it’s safe to cancel the old hosting account.
The entire point of this order is that DNS only switches after the new site has already been proven to work. Nothing about a WordPress migration without downtime depends on luck, it depends on testing happening before the switch, not after.
Don’t cancel your old hosting account on the same day you switch DNS. DNS propagation isn’t instant for every visitor, regardless of TTL. Keeping the old host active for 48 hours is what gives you a safety net if anything unexpected shows up after the switch.
Most of the process, backup, setup, cloning, and testing, can be done within a day. The 24-hour TTL lowering period is the main fixed wait, so plan for roughly two days from start to finish if done carefully.
Not strictly. The free version of either plugin handles a standard backup and restore well. Premium becomes worth it specifically for direct server-to-server migration, since it skips the manual work of separating and re-uploading files and database yourself.
Switch the A record back to the old host’s IP address. Since the old hosting account is still active for 48 hours, this reverts visitors back to the working site while you investigate the issue on the new host separately.
If you’re comfortable with DNS settings, file transfers, and methodical testing, this is genuinely doable yourself. If any of those feel unfamiliar, a botched migration usually costs more in downtime and lost enquiries than getting it done properly the first time.
We run zero-downtime migrations as a standard part of our process, tested and verified before DNS ever changes. See our WordPress migration service, or book a free call to talk through your specific setup.
