InstaWP

InstaMigrate provides authenticated REST API endpoints that enable full WordPress site migrations between servers. It handles database export/import with binary-safe hex encoding, file archiving and transfer, and serialization-aware search-replace for domain changes.
Features:
<ul>
<li>Database export with binary-safe hex encoding (preserves serialized PHP data)</li>
<li>Database import with streaming line-by-line parsing (handles large dumps)</li>
<li>File upload, download, archiving (tar.gz/zip), and extraction</li>
<li>Serialization-aware search-replace for domain migrations</li>
<li>Dual authentication: API key header or WordPress Application Passwords</li>
<li>WP-CLI detection (informational, reported in status endpoint)</li>
<li>Admin UI showing API key and endpoint documentation</li>
</ul>
Important: This plugin grants full database and filesystem access via its REST API. Deactivate and delete it immediately after your migration is complete.

webxmedia

This plugin has been developed by WEBxMedia LTD to enable the transfer of users belonging to one WordPress role to another. This plugin originated from the need to move a group of users to a new role, as the existing role was being demoted (reduced permissions) for new user sign-ups. It’s simple and straightforward to use, and we have plans to enhance this plugin to enable more granular control over which users are transferred.
