I think Archer died shortly after the 1701 was launched. I don't remember where it is from, I think someone found a screenshot from the mirror universe episode where they are looking at his bio. He was also President of the Federation. So he's probably dead by the time of the new movies. It may be slightly different than the Prime universe, but I doubt any differences in the timeline would have affected him much.

Just like Uga.
