The Unlimited Extension is an official add-on for the All-in-One WP Migration plugin. It removes all file upload limits and allows you to import website backups of any size — even 5GB+ .wpress files.

Most hosting providers limit file uploads to:

• 128 MB
• 256 MB
• 512 MB

This add-on bypasses these hosting restrictions and ensures smooth migration of large readymade websites.

Readymade WordPress websites often contain:

• High-quality images
• Multiple page templates
• Large plugins and theme files
• Premade media libraries

This results in .wpress files that may exceed your hosting upload limit. Without this add-on, the import will fail or freeze.

Step 1: Download the Extension

You will receive a ZIP file for the Unlimited Extension plugin.

Step 2: Install the Plugin

• Go to Plugins → Add New
• Click Upload Plugin
• Upload the Unlimited Extension ZIP file
• Click Install Now
• Click Activate

The extension will automatically integrate with All-in-One WP Migration.

Step-by-step Import:

• Go to All-in-One WP Migration → Import
• Click Import From → File
• Select your large .wpress file
• The file begins importing without size restrictions
• Follow on-screen steps to complete import

With Unlimited Extension, imports that previously failed due to file size will complete smoothly.

1. Import freezes at 0%

Increase PHP limits in your hosting panel:

• memory_limit = 512M
• max_execution_time = 600
• upload_max_filesize = 1G
• post_max_size = 1G

2. “Unable to import” error

Ensure Unlimited Extension is activated.

3. “Server Error 500”

Your hosting may have restricted resources. Upgrade to a better plan or temporarily increase PHP limits.

4. Import stops midway

Close all other browser tabs and avoid switching windows while importing.
