ImpEx is a WordPress plugin that allows you to import and export data from and to your WordPress installation.
The primary goal for ImpEx is to provide a true Open Source WordPress Plugin for importing/exporting your WordPress data (including data from third-party plugins/themes).
This plugin is in an early (but working) stage.
Impex provides :
<ul>
<li>
WordPress hooks for third-party plugins to expose their own data to ImpEx Import / Export without being dependent on Impex.
</li>
<li>
a (semi) streaming architecture for large data exports/imports.
</li>
<li>
Definition of configurable import/export profiles defining data providers to use and configuration of these data providers
<ul>
<li>A user interface for importing / exporting data via ImpEx WP admin screen</li>
</ul>
</li>
<li>
the ImpEx API is designed to support resumable/cancelable imports and exports.
</li>
<li>
ImpEx provides a REST API integrated into WordPress
</li>
<li>
ImpEx is explicitly designed for use in managed WordPress instances
</li>
<li>
ImpEx development relies heavily on PHP unit testing its feature set to be stable and consistent.
</li>
<li>
a <a href="https://ionos-wordpress.github.io/cm4all-wp-impex/impex-cli.html" rel="nofollow ugc">CLI</a> for importing/exporting data via ImpEx REST interface. 
The ImpEx CLI can be used as an alternative to the ImpEx WP admin screen.
</li>
<li>
related NPM package <a href="https://www.npmjs.com/package/@cm4all-wp-impex/generator" rel="nofollow ugc">@cm4all-wp-impex/generator</a> enabling transformation of any content to Impex Export format.
Using this package you’re able to convert any content to WordPress and import it using the ImpEx plugin. See the <a href="https://ionos-wordpress.github.io/cm4all-wp-impex/cm4all-wp-impex-generator/static-website-tutorial.html" rel="nofollow ugc">Tutorial</a> 
or <a href="https://www.youtube.com/watch?v=pjG69RmULYo" rel="nofollow ugc">watch the walk-trough at YouTube</a>.

</ul>
Your help is welcome !!

<h3>External services</h3>
<h4>Wasabi cloud storage</h4>
This plugin can connect to Wasabi so you can upload backups to your own Wasabi bucket and download them later.
When cloud storage is enabled, the plugin sends the backup file, the configured bucket and region, and the Wasabi credentials you entered in the plugin settings to Wasabi’s API endpoints over HTTPS.
Wasabi Terms of Service: https://wasabi.com/legal/terms-of-use/ 
Wasabi Privacy Policy: https://wasabi.com/legal/privacy-policy/
This WordPress.org package does not require any external service by default. If Wasabi is left disabled, the plugin works locally and does not connect to Wasabi.

Migrator & Backup

Export, import, and back up WordPress sites, including ZIP and .wpress migrations, with optional Wasabi cloud storage.
