Bypassing All-in-One WP Migration version check while exporting

Current the plugin is requiring latest addon version in the export process. You can use below custom mu-plugin to disable this:

<?php
/**
 * Plugin Name: AI1WM Disable Version Check
 * Description: Disables All-in-One WP Migration extension version checking to prevent "Extension is out of date" errors
 * Version: 1.1
 * Author: GPL Coffee
 *
 * This mu-plugin bypasses version compatibility checks for All-in-One WP Migration extensions

Creating new mu-plugin: creating a new php file, e.g ai1wm-disable-version-check.php, and locate it in /wp-content/mu-plugins folder with above code.
