Increase 512MB Upload Limit for All-in-One WP Migration Plugin

IMPORTANT UPDATE (08/29/2018)
For the instructions outlined in this tutorial to work, you must use version 6.77 or earlier of the All-in-one WP Migration Plugin.
You need to use the old version of All-in-One WP Migration Plugin 6.77 here.

There are 7 steps in this tutorial:

• 1. Activate Plugin
• 2. Open Plugin Editor
• 3. Select Plugin
• 4. Open Constants.php File
• 5. Edit Constants.php File
• 6. Save Changes
• 7. Test Settings

1. Activate Plugin

Make sure that your All-in-One WP Migration plugin is activated.

2. Open Plugin Editor

From your WordPress sidebar menu, click on Editor under the Plugins column.

3. Select Plugin

In the upper right-hand corner of the Editor page, select the All-in-One WP Migration plugin.

4. Open constants.php File

After selecting the All-in-One WP Migration plugin, select constants.php from the list of plugin files.

5. Edit constants.php File

Scroll down to line 249 of the constants.php file to the Max File Size section, and add * 20next to the existing number as shown below:

// ================= 
// = Max File Size = 
// ================= 
define( 'AI1WM_MAX_FILE_SIZE', 536870912 * 20 );

6. Save Changes

Scroll to the bottom of the page and click on Update File in order to save changes.

7. Test Settings

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!
