// =================

// = Max File Size =

// =================

define( 'AI1WM_MAX_FILE_SIZE', 536870912 * 20 );

If your changes were successful, you will notice that the maximum upload filesize has been increased to 10GB.

IMPORTANT

Additional Information

If you ever need to increase the upload limit to more than 10GB, simply increase the multiplier. By using a multiplier of 60 instead of 20 (as shown below) you would increase your upload limit to 30GB.


// =================

// = Max File Size =

// =================

define( 'AI1WM_MAX_FILE_SIZE', 536870912 * 60 );

Be aware that the upload limit will revert back to 512MB whenever the plugin is updated, so you will need to repeat this tutorial if you ever update the plugin.

Advanced Users

If you prefer to edit the file from outside of WordPress, you can find the plugin’s contants.php file by using the following file path:

/wp-content/plugins/all-in-one-wp-migration/constants.php

For Google Cloud, AWS, and Azure users – use the file paths below to locate your constants.php file.

If you’re using WordPress Bitnami, your constants.php file will be located at:

/opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/all-in-one-wp-migration/constants.php

If you’re using WordPress Click-to-Deploy, your constants.php file is located at:

/var/www/html/wp-content/plugins/all-in-one-wp-migration/constants.php

That’s it!
