What makes Prime Mover unique to other existing migration and backup plugins?
  • The free version has no restriction on package size, number of websites, mode of migration (single-site or multisite will work). We don’t put that kind of restriction.
  • No need to delete your WordPress installation, create/delete database and all other technical stuff. This 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.
  • This will work on any server modes. Whether you are 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. No need to hire freelancer to do the job. This saves you money.
  • No messing with complicated migration settings, the free version has no settings on it. Only choose a few options to export and migrate, that’s it.
  • No need to worry about PHP configuration and server settings. Compatible with most default PHP server settings even in limited shared hosting.
  • Modern version PHP compatibility ( PHP 5.6 to 7.3).
  • Entirely coded in PHP-fig standards (its following standard PHP coding guidelines).
  • One of the lowest code risk among migration plugins – simply secure to use.
  • 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.

This plugin worked very well, and when I had any questions I was able to get incredible, fast, hands-on customer support. I'm thrilled with it and I'd buy it again! Highly recommend.

Originally I use other popular plugins to migrate sites or do backup. The common problems with the existing backup / migration plugins are as follows: Server timeout stops the export/import process Requires me a new WordPress blank installation Unable to migrate easily from single-site to multisite or vice versa Complicated settings page Prime Mover plugin solves all of this. It includes an intelligent timeout handling. It means that if ever during the export / import restore process, a a server timeout occurs - Prime Mover silently retries until the entire process is done. It does not anymore require you to increase your server timeouts which some hosting is not even allowed. Prime Mover does not require blank WordPress installation. It even uses existing WordPress users even after migration. In my experience, a resetting WordPress site is enough (as it clears content, all plugin data). You don't need to delete your WordPress installation, re-install WordPress etc. The GUI settings is very easy to use, it uses dialog to maintain a single user focus at a time. This removes distraction. This plugin GUI is designed to work even for non-technical / non-developers. There is also a "WordPress debug package" export package that allows you to quickly clone any website and install to your server. This debug package automatically eliminates the media files/uploads directory in the process. Prime Mover automatically adjust the images so it still shows normally after migration. Debug package is useful when you are going to troubleshoot any website in your own local server. Usually its the uploads directory that is the bottleneck in the package restoration process. Prime Mover deals this using "Debug package" type. Finally this is the only free plugin that seems to migrate single-site to multisite , multisite to multisite , single-site to single site. I can easily create one multisite network where I manage all sites and export one of them to single site, very easily. And If I need to put them back to multisite sub-site, it can be done easily. The free version offers so much value already 🙂
