How to Migrate Your WordPress Site Without Downtime

Technology and networking for website migration

Whether you’re switching hosts, moving from staging to production, or consolidating multiple sites, WordPress migration doesn’t have to be stressful. With the right approach, you can move your entire site — database, files, and all — without losing a single page view.

Before You Start: The Migration Checklist

Preparation is everything. Before touching anything, make sure you have:

  • A complete backup of your current site (database + files)
  • Access credentials for both the source and destination servers
  • FTP/SFTP or SSH access to the new server
  • The new database credentials ready
  • DNS access for your domain
  • A plan for handling emails during migration

The Manual Migration Process

If you’re doing it by hand, here’s the step-by-step:

Step 1: Export Your Database

Use phpMyAdmin or WP-CLI to export your WordPress database. If using WP-CLI:

wp db export backup.sql

Step 2: Copy Your Files

Transfer your entire WordPress installation to the new server. Pay special attention to the wp-content directory — that’s where your themes, plugins, and uploads live.

Step 3: Update wp-config.php

Update your database credentials in wp-config.php to match the new server’s database settings.

Step 4: Import the Database

Import the database on the new server and run a search-replace to update URLs:

wp search-replace 'old-domain.com' 'new-domain.com' --all-tables

Step 5: Update DNS

Point your domain’s DNS to the new server. This can take up to 48 hours to propagate worldwide, though it’s usually much faster.

The Easier Way: Use a Migration Plugin

Manual migration works, but it’s error-prone. One missed serialized string in the database, one wrong file permission, and your site breaks in subtle ways that are hard to debug.

That’s why we built migration directly into Backup Migrate Reset. It handles the entire process — database export, file packaging, URL replacement, and restoration — with a single click. No command line needed, no serialization issues, no forgotten files.

Common Migration Pitfalls

  • Serialized data corruption — Simple find-and-replace breaks serialized PHP strings. Always use a tool that handles serialization properly.
  • Mixed content errors — If you’re moving from HTTP to HTTPS (or vice versa), update all internal URLs.
  • File permissions — The new server may have different permission requirements. Check that wp-content/uploads is writable.
  • PHP version mismatch — Ensure the new server runs a compatible PHP version.
  • Caching issues — Clear all caches after migration, including CDN, server-side, and WordPress caches.

Zero-Downtime Migration Tips

  1. Set up the new site first — Get everything working on the new server before changing DNS
  2. Use a temporary URL — Test the migrated site on a temporary domain or IP address
  3. Lower your DNS TTL — Set it to 300 seconds a few days before migration so DNS changes propagate faster
  4. Migrate during low-traffic hours — Less visitors means less risk of data loss during the switch
  5. Keep the old server running — Don’t cancel your old hosting until you’ve verified everything works on the new one

Migration doesn’t have to be scary. With the right preparation and tools, it’s a smooth, predictable process that takes minutes instead of hours.
