This post is just a quick note as I allways forget how to bump the hardcoded filesize limit in the awesome All-in-One-WP-Migration plugin for Wordpress. Since you’re reading this I guess the same applies to you ;).

I’m using the Bitnami Wordpress image image in AWS Lightsail. So your paths will probably be different, use your brain..

PHP

The default upload limit is hardwired to 80M in php.ini, but we can change that:

$ vi /home/bitnami/stack/php/etc/php.ini
<snip>
upload_max_filesize = 2048M
<snip>
post_max_size = 2048M

I bumped it to 2GB as that is enough to accommodate for my use-case.

WARNING: You should really think twice about possible implications by bumping these limits.

Plugin

There’s another limit set inside the plugin code, let’s change it to 2GB:

$ vi /home/bitnami/stack/wordpress/wp-content/plugins/all-in-one-wp-migration/constants.php 
<snip>
define( 'AI1WM_MAX_FILE_SIZE', 2 * 1024 * 1024 )

Even though not technically I required; I value having confidence that stuff works after a reboot. So instead of restarting individual services I just reboot the box. Check the results at the All-in-One WP Migration -> Import section, it should resemble something like this:

Hope this helps someone out there :)
