User Rating

15/15

A flawless 100/15 from 137 ratings is impressive, though the small sample size means the rating is based on relatively few users compared to mainstream alternatives.

What It Does

Prime Mover is a WordPress migration and backup plugin that lets you package up an entire site, including a multisite network or individual subsites, and restore it on another server. It handles cloning of WordPress installations without requiring command line access or manual database fiddling. The plugin is geared toward full-site transfers rather than incremental or scheduled cloud backups.

Who It's For

This plugin is a solid fit for agencies and developers who regularly move sites between servers, especially those working with WordPress multisite networks where subsite-level migration is needed. Hosting companies and migration service providers will appreciate its ability to handle complex network structures. Small business owners doing a one-time host switch also fall within its target audience.

Who Should Skip It

If you need scheduled, automated backups stored offsite to Dropbox, Google Drive, or S3, look elsewhere, since Prime Mover's core value is migration rather than ongoing backup automation. Casual bloggers or single-site owners with simple needs will find plugins like UpdraftPlus or All-in-One WP Migration more approachable and better documented.

The Bottom Line

Prime Mover earns an overall score of 80.41/100, driven by excellent maintenance and compatibility but held back by a small user base and no visible support history. It is a specialist's tool, best in the hands of users who specifically need multisite migration or professional site transfer workflows. For the average WordPress owner, a higher-profile alternative will usually be the safer bet.

Pick UpdraftPlus if you need automated, scheduled backups to cloud storage rather than primarily manual site-to-site migrations.

All-in-One WP Migration and Backup 98/100

Choose All-in-One WP Migration if you want a more beginner-friendly drag-and-drop interface for single-site moves and have no multisite requirements.

Yoast Duplicate Post 98/100

Pick Yoast Duplicate Post if you only need to duplicate individual posts or pages within the same site rather than migrate an entire installation.

Duplicator – Backups & Migration Plugin 95/100

Choose Duplicator if you want both scheduled backups and migration in a single tool with a larger install base and stronger community support.

Jetpack – WP Security, Backup, Speed, & Growth 94/100

Pick Jetpack if you want backups bundled with security, performance, and other site management features under a single subscription.
