Translations:Manual:MigrateUserGroup.php/1/en

migrateUserGroup.php file is a maintenance script to re-assign all users from an old group to a new one. This script is e.g. helpful after you renamed a user group in LocalSettings.php and you want the users, who were member of that group before, to stay in it also after the renaming. Another usecase is when you want to remove a group from all members.
