Allinone Wp - Migration 100gb Fix

Now, if you go to the Ai1WM import screen, it will still show "Maximum upload size: 128 MB." We need to tell the plugin to ignore its own check and use the local file.

Option A (Easiest - Use the CLI version - Recommended for Pros) If you have WP-CLI installed, run:

wp ai1wm import --file=/path/to/your/storage/import.wpress

This bypasses all web limits entirely.

Option B (Manual Hook - For shared hosting without CLI) Add this to your destination site’s wp-config.php (temporarily):

define('AI1WM_MAX_FILE_SIZE', 107374182400); // 100GB in bytes

Then, go to the WordPress admin > All-in-One WP Migration > Import. You will NOT upload via the browser. Instead, use the "Import from File" feature (looks like a little folder icon or text link). Click that, and the plugin will detect import.wpress sitting in the storage directory.

If you have SSH access, use the plugin's CLI commands:

# Export
wp ai1wm export --file=/path/to/backup.wpress


  • Start the export. This may take hours. The plugin will create a single .wpress file.
    • 


    If export fails: Your server cannot package 100GB. You must use command-line (WP-CLI) or manual methods. allinone wp migration 100gb fix
    

    

    The official documentation tries to hide this, but if you have SSH or FTP access to your server, you can bypass the 100GB upload limit entirely by avoiding the upload form.
    

    Step-by-Step Method (Works up to your disk space limit, not 100GB):
    



  • Upload your .wpress file directly into this folder. (Use FTP for best results; if the file is 100GB, this will still take time, but it is more stable than HTTP).
    • 

  • Go to your WordPress Admin (Destination site) -> All-in-One WP Migration -> Backups (Not "Import").
    • 

  • You will see your uploaded file listed in the "Manual Backups" section.
    • 

  • Click "Restore" .
    • 


    Why this works: The plugin doesn't "upload" the file; it simply reads it from the local disk. This bypasses PHP's upload_max_filesize and the 100GB HTTP restriction entirely.
    

    Result: You have just fixed the 100GB limit without changing a single line of code.
    

    

    Adjust PHP settings (php.ini) and webserver config:
    



  • For NGINX: increase client_max_body_size to >= file size. Reload NGINX.
    • 

  • For Apache: configure LimitRequestBody or proxy settings if using PHP-FPM.
    • 

  • Restart web server / PHP-FPM.
Note: web hosters often enforce lower caps; contact host support if you can’t change these.

    To bypass the upload limit in All-in-One WP Migration without paying for the Premium extension, you generally need to modify the plugin's code or adjust your server settings. 🛠️ The Quickest Fix: Edit Plugin Code This bypasses all web limits entirely
    

    This method directly changes the limit defined within the plugin. Go to Plugins > Plugin File Editor. Select All-in-One WP Migration from the dropdown. Open the file: constants.php. Search (Ctrl+F) for the string: AI1WM_MAX_FILE_SIZE.
    

    Change the numerical value to: 100 * 1024 * 1024 * 1024 (this equals 100GB). Save the file. ⚙️ The Server-Side Fix
    

    Even if the plugin allows 100GB, your server might block it. Edit your .htaccess file (usually in the root folder) and add these lines: php_value upload_max_filesize 100G php_value post_max_size 100G php_value memory_limit 1024M php_value max_execution_time 0 php_value max_input_time 0 📦 The "Pro" Workaround (No Plugin Editing)
    

    If the file is truly 100GB, web uploads will often fail due to timeouts.
    

    Use FTP: Upload your .wpress file directly to /wp-content/ai1wm-backups/. Restore: Go to the plugin's Backups tab in WordPress.
    

    Action: Your 100GB file will appear there; just click Restore.
    

    📍 Note: Large migrations often crash on cheap hosting. Ensure your disk space is at least 250GB to handle the compressed file and the extraction process. If you’d like, I can help you: Write a custom PHP function to automate this Troubleshoot timeout errors during the import
