One more advise,IF is going to be a temporary situation, make sure you make a duplicate of your registrations (USB drive), because if you convert the 3000 registrations to use in the T3, and later you get back to the 3000, the SAME registrations(the converted ones to the T3) will NOT work or be recognized by the 3000.
A friend of mine did that, luckily for him that had a backup USB drive with the registrations.
