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 !!

ZHBackup – Restore & Migration is a full-site WordPress backup and restore plugin built for real migration workflows. It packages your database, media, plugins, themes, selected <code>wp-content</code> folders, root files, and optional custom root folders, then restores them through a chunked process designed to avoid request timeouts.
The database is stored as a structured package instead of one large SQL replay file, so large page-builder data, post meta, options, and other oversized values can be restored in smaller, traceable steps. Live activity logs show the progress of exports, imports, database rows, large values, file restore, validation, and cleanup.
After a restore, ZHBackup lets you review the site first and run stale-file cleanup separately from the restore process. This keeps restore completion predictable while still giving you a controlled way to remove old plugins, uploads, themes, and selected root-folder files that are not present in the backup.
Key Features:
<ul>
<li>Full-Site Backups — Back up the database, uploads, plugins, themes, mu-plugins, selected <code>wp-content</code> folders, root files, and optional custom root folders.</li>
<li>Structured Database Package — Export database schemas, row chunks, and large values separately for reliable restores of Elementor/page-builder data and other large rows.</li>
<li>Chunked Export and Restore — Process database and file operations in small AJAX steps to reduce timeout and memory-limit issues.</li>
<li>Browser Upload or Server Restore — Upload backups through the browser in resumable chunks, or place backups on the server via FTP/SFTP and restore from a table of available files.</li>
<li>Flexible Archive Formats — Create standard <code>.zip</code> backups or optimized <code>.zhbackup</code> archives.</li>
<li>Live Activity Logs — Follow professional export/import logs with database checkpoints, row counts, large-value restore events, file progress, validation, and cleanup status.</li>
<li>Post-Restore Cleanup — Save a cleanup plan after restore and run stale-file cleanup manually after reviewing the restored site.</li>
<li>Serialized-Safe Find & Replace — Update URLs safely across serialized PHP data, JSON-escaped URLs, and Elementor widget data.</li>
<li>Secure Backup Storage — Store backups outside the webroot when available, with <code>.htaccess</code>, <code>web.config</code>, and <code>index.php</code> protections when stored inside the site.</li>
<li>Retention Policies — Automatically clean up older backups by count or age using WP-Cron.</li>
<li>No Required Account — Use all backup, restore, migration, and cleanup features without a license key or forced signup.</li>
</ul>
WordPress.org Compliant:
<ul>
<li>No obfuscated or encoded PHP</li>
<li>Proper sanitization for all inputs</li>
<li>Escaped outputs throughout</li>
<li>Nonces for all form submissions</li>
<li>Capability checks on every action</li>
<li>No hidden external API calls</li>
<li>No telemetry without explicit consent</li>
</ul>
<h3>External services</h3>
ZHBackup includes an optional newsletter signup form on the plugin Settings page.
This feature connects to an external service hosted by Hassan Zain at <code>hassanzain.com</code>. It is used only to add the submitted email address to the ZHBackup newsletter or product updates list.
Data is sent only when an administrator manually submits the optional signup form. The plugin does not contact this service during normal backup, restore, migration, import, export, or find-and-replace usage.
When the form is submitted, the plugin sends:
<ul>
<li>Email address entered in the signup form</li>
<li>Site URL (<code>home_url()</code>)</li>
<li>Plugin slug (<code>zhbackup</code>)</li>
<li>Plugin version</li>
</ul>
Terms of service: https://hassanzain.com/terms-and-conditions 
Privacy policy: https://hassanzain.com/privacy-policy
<h3>Privacy</h3>
ZHBackup does not send telemetry or usage analytics during normal backup, restore, migration, import, export, or find-and-replace operations.
The only optional external data transfer is the administrator-initiated newsletter signup described above.
