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.

BasePress

If you are using BasePress Knowledge Base in your site, chances are that you may need to move all of its content to a new site. 
BasePress Migration Tools is the easiest way to do that. It generates an export file with all the Knowledge Bases, sections, articles and settings data. 
You can then import the content using the same Migration tools in the destination site.
⚠️ It is strongly recommended to create a backup of both source and destination sites before exporting and importing content.
<h4>What it does</h4>
The BasePress Migration tools generates a xml file to import all knowledge base data to a new site. 
It will also update the links to any media files and internal links with the new site domain. 
Apart from export/import the Migration tools can also be used to remove all BasePress data from a site.
<h4>What it doesn’t do</h4>
The BasePress Migration tools doesn’t transfer any of the attached media files used in the KBs, sections and articles. 
You would need to manually transfer them via FTP from your source site to the destination site respecting the URL structure.
