mass effect tranfering data question

i finished mass effect a long time ago and dont quite remember but wasnt mass effect one of those games that once you finished it you could only start a new game with the same character or start from the last checkpoint(before finishing the game)?if so then how can you transfer data from an unfinished game or a new campaign?because once i finished mass effect i decided to keep playing with the same character but stoped during like the begining of the game, so the only save i got right now is the save from starting the game againg with the same character, so how will i be able to transfer my completed game?mass effect tranfering data question
If your talking about ME2 then probably not if you only have your last save on the new game. But if you still have your old ones you should be alright.

Why make two threads on this though?
