The actual backup system dont let you transfer resellers account with easy. You have to first do a backup of the user/reseller, then, restore it, then change from user to reseller with a 3rd script, and then restore all the users of that reseller..
Maybe a 'backup reseller and users' with a 'restore resellers and users' feature?
