refingerprinting, fbi was unable to process fingerprint

My dad didnt get his original green card, it was sent back to USCIS and was destroyed so he applied for a new one. After a week of us sending our application for a replacement we already got his biometrics appointment. It took him a while to finish his fingerprinting because his hand is really sweatty but the technician told her that it is okay and there are a lot of people with the same issues. After two weeks, we received an ASC appointment to have his fingerprint retaken. The problem now is he is moving to another state in a week after this appointment and is going to do a change of address the day he gets there. He got a nonrefundable flight so we cant cancel (or else we have to pay almost the same amount of the ticket for changing the flight) and move it an extra week for us to be sure if they need him back for a 3rd re print. My question is if this 2nd finger prints are going to be rejected again, does he need to go back to the original place where he got fingerprinted the first time or will they automatically change his fingerprinting location to where he is at at the present time. Any information will help and im thanking everyone who'd be reading this in advance.
