Essential Tips for Migrating a Multisite WordPress Network

Migrating a WordPress Multisite Network can be a complex task, especially when dealing with multiple interconnected sites. A successful migration requires careful planning, execution, and testing to ensure no data is lost, and all sites remain functional. Whether you’re moving to a new host, domain, or server, this guide will cover essential tips and best practices for migrating your WordPress Multisite Network efficiently.

Understanding WordPress Multisite Migration

A WordPress Multisite Network allows you to manage multiple sites from a single WordPress installation. While this is convenient for management, it also means that migrations are more intricate than for standalone WordPress sites. Migration typically involves moving the database, files, themes, plugins, and configurations.

Why Migrate a Multisite Network?

You might need to migrate your Multisite Network for several reasons:

• Upgrading to Better Hosting: Improved performance and scalability.
• Changing Domain Names: Rebranding or restructuring your online presence.
• Server Changes: Shifting to a new server for better resources.
• Backup and Recovery: Creating a clean slate or restoring after an issue.

Key Challenges in Multisite Migration

• Database Complexity: A single database contains tables for all sites, making data separation and migration intricate.
• File Structure: Uploads for all sites are stored in the same folder, requiring careful handling.
• Domain Mapping: Subsite domains or subdirectory structures must be updated.
• Network Configuration: Ensuring all plugins, themes, and custom settings function as intended post-migration.

Preparation Before Migration

1. Perform a Full Backup

Create a complete backup of your WordPress installation, including:

• Database (using tools like phpMyAdmin or plugins such as UpdraftPlus).
• Files (via cPanel, FTP, or SFTP).

2. Audit Your Multisite Network

• Evaluate Active Sites: Ensure all sites are functional and prune any inactive ones.
• Check Plugins and Themes: Disable unnecessary plugins and delete unused themes.

3. Confirm Hosting Requirements

Ensure the new server or hosting environment supports WordPress Multisite features, including wildcard subdomains or subdirectories.

4. Install Necessary Tools

• Use plugins like All-in-One WP Migration Multisite Extension or WP Migrate DB Pro for easier migration.

Steps for Migrating a Multisite Network

1. Export the Database

• Access your database via phpMyAdmin and export it as an SQL file.
• For large databases, use tools like WP-CLI to avoid timeout issues.

2. Transfer Files

• Use FTP/SFTP or a file manager to download the following:
  • wp-content folder (includes themes, plugins, and uploads).
  • wp-config.php file for site settings.
• Upload these files to the new server.

3. Modify wp-config.php

Update the wp-config.php file to match the new server settings:

• Update database credentials (DB_NAME, DB_USER, DB_PASSWORD, DB_HOST).
• Check for Multisite-specific configurations such as DOMAIN_CURRENT_SITE and PATH_CURRENT_SITE.

4. Update the Database

Use a search-and-replace tool to update old URLs, domains, and paths to reflect the new environment. Recommended tools:

• WP-CLI Search and Replace Command
• Better Search Replace Plugin

5. Configure DNS Settings

If you’re using subdomains, update the DNS settings to point to the new server’s IP address. For subdirectory setups, ensure the root domain is correctly configured.

6. Test the Migration

• Access the main site and all subsites to confirm they function correctly.
• Test login functionality, navigation, plugins, and themes.
• Fix broken links or missing images.

Post-Migration Optimization

1. Enable Caching

Use plugins like WP Super Cache or W3 Total Cache to optimize loading times.

2. Set Up a CDN

Integrate a Content Delivery Network (CDN) like Cloudflare to serve assets faster and reduce server load.

3. Check SEO Configurations

Ensure your SEO plugins (like Yoast or Rank Math) are configured correctly for each subsite. Update sitemaps and verify them with Google Search Console.

4. Monitor Site Performance

Use tools like GTmetrix or Pingdom to monitor the performance of your migrated network.

Common Mistakes to Avoid

1. Skipping Backups: Always back up your files and database before migrating.
2. Not Updating URLs: Failing to update URLs in the database can break your sites.
3. Ignoring File Permissions: Incorrect permissions may cause access or upload issues.
4. Neglecting Subsite Testing: Check each subsite individually post-migration.
