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.
