Technical Report: All-in-One WP Migration Large File Handling (100GB+)

Date: October 26, 2023 Subject: Performance Bottlenecks and Resolution Strategies for 100GB+ Migrations Plugin Version: All-in-One WP Migration (Latest)

The Technical Trio of Limits

  1. PHP upload_max_filesize: Usually set to 2MB to 100MB by default.
  2. PHP post_max_size: Usually slightly larger than the upload limit.
  3. PHP max_execution_time: The script cannot run for 10+ hours. At 100GB, uploads take hours.
  4. Memory Limit: Trying to extract a 100GB .wpress file requires massive RAM.
  1. Upload the 100GB .wpress file to the server via SFTP (FileZilla/WinSCP) to bypass HTTP timeouts.
  2. Move the file to the specific import folder (usually wp-content/ai1wm-backups/).
  3. Do not use the browser. Connect via SSH (Terminal/Putty).
  4. Navigate to your WordPress root directory.
  5. Run the import command via WP-CLI (if supported by the extension version) or use the server's internal cron job to trigger the import script manually.

If you tell me your hosting provider (e.g., Bluehost, SiteGround, VPS), I can give you the specific file paths or PHP settings needed for your server.
