I think, if I was to replace my whole transom, I would take the whole thing out and replace it front and back. I would do it just for delamination reasons. I still believe the best way to be sure is to epoxy front and rear. And build up a much stronger transom. If you get any delamination you would be back to square one in a few years.
I've never replaced a transom, but I've made a few. I think I'm kind of alone on that line of thought. I've repaired transoms on wooden boats and I've always been acused of overkill but I never repaired on twice.
