Below are practical fixes and steps to import or export very large sites (around 100 GB) with the All-in-One WP Migration plugin.
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 are determined to upload directly via the browser (not recommended for 100GB, but useful for files in the 2GB-10GB range), you must edit your server configuration. allinone wp migration 100gb fix
You need to edit your php.ini file (access via cPanel, FTP, or ask your host).
Add or modify these lines to values higher than your file size:
upload_max_filesize = 120G
post_max_size = 120G
memory_limit = 512M
max_execution_time = 3000
max_input_time = 3000
Note: Many shared hosting providers (like Bluehost, GoDaddy, etc.) will not allow you to override these settings manually. You may need to contact their support and ask them to increase the limits for you. Below are practical fixes and steps to import
If you must import directly to a live server, you cannot use the drag-and-drop interface. You must use the CLI (Command Line Interface).

Procedure:
Sometimes the plugin fails because it miscalculates free space. In lib/model/class-ai1wm-backups.php, comment out the disk space check:
// if ( $disk_free_space < $total_files_size )
// throw new Ai1wmNotEnoughDiskSpaceException( __( 'There is not enough disk space...', AI1WM_PLUGIN_NAME ) );
//
