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 8.2+ (Google Drive feature requires at least PHP 7.4).
  • 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.

Transfers everything properly and no need to do any post transfer fixes. Amazing. Worked with Single and Multi site configs. Thank you! I'll be supporting you when I can

Works perfectly, even with the free version. Migrating from or to multisites, exporting as single site from multisite and so on is easy and just works. Thank you for your effort!

One of the least pleasant things about the WordPress ecosystem is how many freemium plugins exist where the free version provides nothing useful, and the premium version provides functionality that should be in WordPress core.This isn't like that. If you run multiple WordPress installs, and especially if you run Multi-Site, Prime Mover does basically everything you need, for free, and it works great. Can be used to move from site to site or from multi-site to single instance and back, or to manage a staging site. Should rank higher on wordpress.org than all of the other site duplicators which are way more limited and don't work as well.
