To increase the All-in-One WP Migration upload limit to 100GB for free, you must use an older version of the plugin (v6.77 or 6.7) and manually modify its core files . Modern versions have patched these limits to encourage the purchase of their Unlimited Extension . Step 1: Install a Compatible Version
| Problem | Fix |
|---------|-----|
| Memory exhausted | Add to wp-config.php: define('WP_MEMORY_LIMIT', '1024M'); |
| Import stops at 0% | Check error_log. Often a missing PHP module (zip, curl). |
| Uploads too big for CLI | Use rsync -avz --partial user@old:/wp-content/uploads/ /new/uploads/ |
| Timeout during import | Use screen -S migration + wp ai1wm import ... – reattach with screen -r |
Install All-in-One WP Migration on the destination. Do NOT import yet. Just install and activate the free version (or the unlimited version—both work).
The story of the " All-in-One WP Migration 100GB fix " is a classic digital workaround tale where users bypass modern paywalls by using an older, more flexible version of the software. The Conflict: The Paywall Ceiling
For ~100GB: Change it to define( 'AI1WM_MAX_FILE_SIZE', 2 << 35 ); or simply use a direct byte calculation like define( 'AI1WM_MAX_FILE_SIZE', 100 * 1024 * 1024 * 1024 );.
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.
The process typically involves editing the plugin's core files or server configuration to artificially inflate the AI1WM_MAX_FILE_SIZE constant. However, for a file as large as 100GB, server-side limits and browser timeouts make a standard web upload highly unreliable. Common Technical "Fixes"
