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 !!

Berestov Goods Transfer for WooCommerce copies WooCommerce products from one WordPress site to another through the destination site’s API key.
Supported target stack: 
– WordPress 4.8–6.9 
– PHP 7.0–8.5 
– WooCommerce 2.6+ and modern versions
What it can transfer: 
– single products 
– grouped products and their child products 
– categories 
– featured images and galleries 
– custom fields 
– image URLs found inside custom field text or HTML
How to use: 
1. Install and activate the plugin on both sites. 
2. On the destination site, generate an API key. 
3. On the source site, add the destination site URL and API key. 
4. Test the connection. 
5. Search products by title, add one or more products to the basket, then run Preview. 
6. If the preview looks correct, run Transfer. 
7. For very large catalogs, use Transfer all.
Important safety notes: 
– API only. No direct database connection. 
– Existing items are matched and reused where possible to reduce duplicates. 
– Preview first is strongly recommended. 
– For remote production sites, use HTTPS. The destination setting can explicitly require HTTPS. 
– Use at your own risk. Always test on a staging copy and keep backups before transferring real data.
