  • The free version supports full WordPress multisite migration.
  • 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.

  • The code is following PHP-fig coding standards (standard PHP coding guidelines).

This product is amazing, and the author is incredibly generous providing the MultiSite functionality (especially single-site to subsite of MU) in the base product. After some initial doubts with errors in installation (installed properly but was a disaster at first, prompting a restore from backup), turns out it was just a matter of the unavoidably delicate settings (set to MU for target site) for something involved. I used the packaged method after the alternative took too long (def not the plugin's fault since it's a balance with the effectiveness of the process and ensuring the server doesn't freeze). Our use-case was particularly acute because our cloud provider was strangely frugal with the server settings and refused to increase available resources to stave off a normal process of regular WP import failures borne of memory issues that can be simply changed in php.ini). So thank you for this amazing tool, and your generosity in providing the MultiSite functions in the base package that others would scrimp on. Bravo to you!

Thank you for ending the series of miserable days moving a site with large amounts of data on multisite. Only 1 hour I have transferred 700mb of data with no need to configure much after transferring. It is great that you can use it for free. Sincerely send you 5 stars.

I am lucky to have found this plugin, especially if you use WordPress multisites , this plugin is a blessing. The best part is that you can get a lot of out this plugin for free. And would need premium version only if you manage a lot of sites and need more automation. But the free version should be good for most people in my opinion. Very reliable. and the developer is also very helpful even in the free plugin section.
