What makes Prime Mover unique to other existing migration and backup plugins?

  • The free version has no restriction on package size, number of websites or mode of migration (single-site or multisite will work). (Note: Exporting/Restoring a multisite main site is a PRO feature)
  • The free version supports WordPress multisite migration on any number of subsites except that exporting/restoring the multisite main site is a PRO feature.
  • It can backup WordPress multisite sub-sites or migrate multisite.
  • No need to delete your WordPress installation, create/delete the database, and all other technical stuff. It will save you a lot of time.
  • This is not hosting-dependent. Prime Mover is designed to work with any hosting companies you want to work with.
  • The free version has full multisite migration functionality. This feature is usually missing in most migration plugins free version.
  • Full versatility – migrating from your localhost, dev site, or from a live site to another live site.
  • You will be doing the entire migration inside the WordPress admin. Anyone with administrator access can do it. There is no need to hire a freelancer to do the job – saves you money.
  • No messing with complicated migration settings, the free version has built-in settings. Only choose a few options to export and migrate, that’s it.
  • You can save, download, delete, and migrate packages using the management page.
  • No need to worry about PHP configuration and server settings. Compatible with most default PHP server settings even in limited shared hosting.
  • Prime Mover works with modern PHP versions 5.6 to 8.0+ (Google Drive feature requires at least PHP 7.0).
  • The code is following PHP-fig coding standards (standard PHP coding guidelines).
  • The free version supports backup and restoration of non-UTF8 sites. However, you need the PRO version to migrate non-UTF8 to the UTF8 (utf8mb4) database charset and vice versa.
  • You don’t need to worry about setting up users or changing user passwords after migration. It does not overwrite existing site users after migration.

I have spend almost a week debugging a multisite migration problem. Other plugins in the past were cumbersome. So I was a bit skeptical. But it definitely is worth 5 stars. I had spammed my hosting provider in pure frustration. This solution is one that should be in the helpdesk knowledge base etc. The install of this plugin was simple and clean. No difficult questions in order to fine tune the process. The process took less then 20 minutes! It is also a great backup tool. After completing the process, it gave me a permalink that instantly worked. Conclusion, very good and worth buying.

A lot of my websites are quite massive and difficult to pullout as they're in a multisite format, which makes it tricky to get all of the tables. This has helped me make demo sites I can show others a fairly straightforward process. I really appreciate the effort and generosity of the author to provide this freely for others to use.
