Exactly! The question was on how to change them over... Because obviously the choice has already been made to feed live. Funny thing is that debate always pops in off topic...
Piebald... I would definatley start with either really stunning or pre killing the prey for the ones that are used to f/t... just in case they can't handle a live and kickin one for their first couple times. Chances are they will take a live fine... But it is best to take little steps when introducing something new.
