Moving players from roster to roster

On NBA 2k14, I'm trying to move players on one roster file and have them replace the players on another roster file and was wandering if anyone could tell me how to do that or if it's even possible? I'm on Xbox 360 if that changes anything. Help would be much appreciated.

Download RedMC. If ur on PC I can really help you. Though I'm not sure if Xbox is supported by RedMC. It would have definitely the same process with PC.
