How to Migrate a Large WordPress Site with Migrate Guru

Large migrations fail for boring reasons: the archive is too big, PHP kills the process, storage fills up, or the browser connection drops. Migrate Guru runs the migration on its own servers instead of loading the source site. That helps on media-heavy sites and restricted hosting.

It doesn't remove the need for preparation. The destination still has to be compatible and correctly configured.

Prepare the Source Site

Start with an independent backup. A migration service is never your only recovery plan.

Then clean up obvious disposable weight: old local backups, cache directories, temporary exports, abandoned staging copies. Don't delete anything you can't identify. The goal is to trim the transfer, not to do a risky cleanup right before a move.

Write down the current PHP version, important extensions, permalink structure, active theme, and critical plugins. For a busy site, pick a low-traffic window.

Prepare the Destination

Create the hosting account. Install a fresh WordPress. Confirm the destination URL opens and you can log in.

Match or exceed the source environment:

• Compatible PHP version and extensions
• Enough disk space
• Valid database and file access
• SSL certificate for the live domain
• Enough resources for the site after launch

Don't change public DNS yet. The new copy gets tested before visitors reach it.

Install and Start Migrate Guru

Install Migrate Guru on the source site. Activate it. Open the plugin, enter the requested email, accept the terms, and continue to host selection.

Choose the destination host if it's listed. Host-specific integrations reduce the connection details you have to enter. If it's not listed, use the alternative connection method and get the correct details from the new host.

Connection info may include the destination URL and SFTP, FTP, cPanel, or hosting credentials. Use a temporary account when the host supports one. Remove it after migration.

Confirm the Destination

Before starting, check the destination domain and directory. A typo sends the site into the wrong folder or overwrites an install you meant to keep.

If the domain stays the same, Migrate Guru may use a temporary destination during the transfer. Follow the host's instructions. Don't change DNS early.

Start and Monitor the Migration

Begin the migration. Leave the source site available. Migrate Guru reports progress while its service transfers and processes the site.

Don't make major changes during this window. A brochure site can usually stay online. A store, membership site, or active publication may receive new data after the migration starts. Plan how those late orders, users, or posts get synced before launch.

If the process stops, read the error and any notification email. Recheck credentials, disk space, firewall rules, and access restrictions before restarting. Repeating the same wrong credential won't fix anything.

Test Before Switching Traffic

Use the host's preview URL, a temporary domain, or a local hosts-file entry to inspect the migrated site. Test:

• Front-end pages and images
• WordPress login and user roles
• Forms and outgoing email
• Search, scheduled tasks, and integrations
• Mobile layouts
• Checkout, payment sandbox, and order emails (if WooCommerce)

Clear caches and save permalinks if inner pages return 404s. Check the PHP log for warnings that didn't appear on the old server.

Complete the Launch

When the copy passes testing, sync any content created after the initial transfer. Put a dynamic site into a short maintenance or read-only window if needed. Update DNS.

Keep the old hosting active while DNS propagates. Monitor errors, forms, transactions, and performance from more than one network. Cancel the old account only after the new site and its backups have been stable.

Before You Cancel the Old Host

Migrate Guru is most useful when a browser upload or server-built archive would struggle. The remote processing reduces pressure on the source. The safe-migration rules stay the same: keep a backup, verify the destination, handle changing data, and test before launch.
