Scope: Prime Mover Free / Pro version

IMPORTANT : If you are using Prime Mover Pro for the first-time , please read this get started guide first.

This tutorial illustrates how to migrate an existing sub-site in a multisite to another multisite. This tutorial applies for both Prime Mover Free and Pro Version. The target site installation could reside in a different server or your localhost.

Migration concepts

When migrating a multisite sub-site to another multisite subsite. It’s important that the blog ID matches. Otherwise Prime Mover won’t be able to restore this.

You don’t need to worry about this as Prime Mover handles all of this automatically for multisite to multisite migration.

When you generate a package for a given multisite sub-site, the blog ID is automatically exported and will be used to identify and validate the restoration process.

When this package is migrated to another multisite, Prime Mover reads the blog ID of the exported package and compare it with the blog ID of the target site. If it matches, it implies the export package is correct for the target site. Otherwise, if the blog ID won’t match, the restoration process is denied.

Blog ID comparison is used to prevent an existing multisite sub-site to be accidentally overwritten during any migration process. Prime Mover ensures that the migration process only happens between two sites having the same blog IDs. Other, sub-sites in the multisite network should be left untouched.

Generating multisite export package

  • Install the latest version of Prime Mover plugin.
  • Login as network administrator and network activate.
  • Optionally opt-in to Freemius notifications.
  • Go to Network Sites.
  • Search the sub-site that you would like to export.
  • Select appropriate export options.
  • Click Export Now. Wait until the export process is completed. Do not close or refresh the window.

Restore Package

  • Install the latest version of Prime Mover plugin. It should be the same version as the one used to create the export package.
  • Login as network administrator and network activate.
  • Optionally opt-in to Freemius notifications.
  • Go to Network Sites.
  • Search the sub-site that you would like to be restored.
  • Click Restore button.
  • Browse to the exported package zip.
  • Prime Mover validates the exported package zip (e.g. analyze the blog ID vs the target blog ID).
  • If it matches, Prime Mover ask you to confirm the restoration.
  • If you proceed, wait until the restoration process is completed. This process might take some time depending on the size of the package.
