WordPress Website Migration: The Complete Guide (2026)

Before You Start

Make sure you have the following in place first:

• A recent, verified backup (see our backup guide), this is genuinely your undo button if anything goes wrong
• Your new hosting account already set up and ready to receive your site
• A low-traffic window scheduled for the actual switch, to minimize any visitor impact

Moving your WordPress site to a new host sounds intimidating, and the honest truth is it can genuinely go wrong if you skip the boring preparation steps. The good news: nearly every migration horror story traces back to the same handful of avoidable mistakes, all fixable with a bit of upfront planning.

The 5 Stages of a Safe Migration

1. Back up everything, files and database, before touching anything
2. Move your files and database to the new host
3. Rebuild the site on the new server
4. Point your domain to the new hosting environment
5. Test thoroughly before fully decommissioning your old host

Stage 1: Prepare Before You Touch Anything

Preparation is what separates a smooth migration from a painful one.

• Create a complete backup of your files and database, not just one or the other.
• Document your site’s technical details, PHP version, MySQL version, and active plugins and themes, so you can confirm your new host supports everything.
• Update WordPress core, plugins, and themes before migrating, see our safe update guide. Outdated software is a leading cause of migration errors.
• Delete unused plugins and themes, inactive code adds unnecessary risk during the move.
• Choose a low-traffic window to minimize disruption to real visitors during the switch.

Stage 2: Choose Your Migration Method

For most WebGomu readers, a plugin-based migration offers the best balance of safety and simplicity, no FTP client or phpMyAdmin required.

Stage 3: Move Your Files and Database

Using a free tool like Duplicator, the process typically looks like this:

1. Install and activate the Duplicator plugin on your current site.
2. Create a new backup, selecting all components (files and database) to include.
3. Let Duplicator scan your site and flag any potential issues before building the package.
4. Click Build, then download both the resulting archive and installer files.
5. Upload both files to your new host, then run the installer to unpack and configure everything automatically.

Stage 4: Point Your Domain to the New Host

Once your site is rebuilt and verified on the new server, update your domain’s DNS settings to point to it. DNS changes aren’t instant, propagation can take anywhere from a few hours up to 48 hours, during which some visitors may briefly see the old server and others the new one.

Stage 5: Test Before You Fully Commit

Thoroughly test the new site before canceling anything on your old host: check that pages load correctly, forms submit properly, images display, and your permalink structure is intact and matches exactly what it was before, changed URLs are one of the fastest ways to lose existing SEO rankings during a migration.

WebGomu Tip: Keep your old hosting account active for about a week after going live on the new one. If something unexpected surfaces once real traffic hits the new site, this gives you a genuine fallback rather than a full emergency recovery.

Preserving Your SEO During Migration

Retaining your existing URL structure, metadata, and headings is critical, this is exactly why confirming your permalink structure didn’t change matters so much. Once your migration is complete, run a fresh SEO check for broken links or missing metadata that might have been introduced during the move, the same way you’d audit any major site change.

Troubleshooting

Error establishing a database connection

Double-check your database name, username, and password in wp-config.php, and confirm the database user has correct permissions on your new host.

White screen after migration

This usually indicates a plugin or theme conflict. Disable all plugins via FTP by renaming the /plugins/ folder, then reactivate them one at a time to isolate the cause, the same diagnostic method covered in our WooCommerce troubleshooting guide.

Site shows “Not Secure” after the move

Force HTTPS in your new host’s control panel and update any hardcoded image or script URLs still pointing to http://. See our SSL guide if you need the full setup walkthrough.

Common Mistakes

• Skipping the pre-migration checklist, the single biggest cause of broken migrations.
• Migrating outdated plugins and themes instead of updating them first.
• Changing permalink structure during the move, breaking existing URLs and rankings.
• Canceling the old hosting account immediately instead of keeping it as a brief fallback.

Recommended Tools

Key Takeaways

• Keeping your exact permalink structure intact is critical for preserving SEO rankings.
• Keep your old host active briefly after going live, as a genuine safety net.
