Migration settings
From MoodleDocs
This feature is part of Moodle Workplace™, which is available through Moodle Partners only.
This page is part of Moodle Workplace's Migration tool and can be found in General > Migration settings.
The Allow course content backup settings controls whether users who have the permission to backup courses (moodle/backup:backupcourse) are allowed to include content as part of a migration export. If not set (the default), only users who have permission to edit site configuration (moodle/site:config) can export content as part of migration.
Enabling this setting is likely to cause a significant increase in the size of your migration export files.
