I have gone this route a couple of times. It was an interesting exercise,
but not one I would recommend. It works, but things like the transition
from ufs to ufs2 and new threading libraries and LOTS more make it a
rough way to go. I think the advise to do a fresh install is the best
option if you go to 5, but I'd really recommend staying at 4.10 or
STABLE for now.
