According to the most resent movie, Starfleet has yet to go on any five years missions.
Which is odd, I think. First off, the NX-01 went on a 2 year mission a hundred years back. I'd think they'd have managed to do 5 by now. Second, Cardassians are mentioned in the first movie, which is odd, to say the least. You get the impression that they traveled further by 2255 than in the Prime timeline.
