What Is Multisite Childsite Migration

WPvivid Backup & Migration Pro supports migrating an individual site (childsite) within a WordPress Multisite network to a separate single-site WordPress installation.

This feature is useful when you want to extract a subsite from a multisite network and run it independently as a standalone WordPress site.

Before Migration

Before migrating a childsite, ensure the following requirements are met:

• Prepare Target Installation
  Ensure the target single site is a fresh WordPress installation ready to receive the childsite data.
• Install WPvivid on Both Sites
  WPvivid Backup & Migration Pro is installed and activated on both the source multisite network admin and the destination single-site installation.
• Deactivate Security Plugins
  Temporarily deactivate security and caching plugins on both sites, as they may write absolute paths that can interfere with migration.

How to Migrate a Multisite Childsite

Follow these steps to migrate a childsite from a multisite network to a standalone WordPress installation.

Step 1: Export the Childsite from Source Multisite

• Go to the source multisite’s Network Admin
• In WPvivid Plugin → Export Site, click Export to Localhost (Web Server).
• In the Backup Content section, select For the purpose of moving a subsite to a single install.
• Enter a subsite title in the search field, or click Search directly to display all available subsites.
• Select the childsite you want to migrate from the list.
• Optionally add a comment for identification purposes.
• Click Export Now.

Step 2: Download the Export Files

• After the export completes, you will see a successful message.
• Click the Download All Parts button to download the backup files to your computer.
• Keep all downloaded files together in the same location if the backup is split into multiple parts.

Step 3: Upload to Target Single Site

• Go to the target single site.
• In WPvivid Plugin → Import Site, click Import from Localhost (Web Server).
• Click Select Files or drag and drop all exported ZIP files into the upload field.
• Ensure all parts are uploaded at the same time if the backup is split into multiple files.
• Click Upload.

Step 4: Restore the Childsite

• After successful upload, you will see a successful message.
• Click Restore Now in the message to begin the restoration process.
• Wait for the restoration to complete.
• Verify the site is functioning correctly as a standalone WordPress installation.

What Gets Migrated

When migrating a childsite to a single install, WPvivid transfers:

• Childsite Database
  All posts, pages, users, settings, and metadata specific to the selected childsite.
• Childsite Content
  Media uploads, custom content, and site-specific data from the childsite.
• Themes and Plugins
  Active themes and plugins used by the childsite.
• Site Configuration
  Childsite-specific settings and configurations (wp-config.php is not overwritten on the target site).

After-Migration Steps

After completing the childsite migration:

• Verify Site Functionality
  Test all pages, posts, media, forms, and critical features to ensure they work correctly.
• Clear Caches
  Clear all caching plugins if any and server-level caches to ensure fresh content delivery.
• Reactivate Security Plugins
  If you deactivated security plugins before migration, reactivate them on the single-site installation.

Best Practices for Childsite Migration

For a successful childsite migration, follow these best practices:

• Perform a test migration in a staging environment before migrating to production when possible.
• Migrate to a fresh WordPress installation to avoid data conflicts and compatibility issues.
• Keep the source multisite network active until you have fully verified the migration was successful.
• Test all site functionality thoroughly after migration, including forms, media, plugins, and integrations.
• Ensure the target server has sufficient resources (disk space, memory, bandwidth) to handle the childsite independently.
