I've used Live Upgrade to take systems from 7 to  9, but have never
done the 9 to 10 thing.  LU seems to (mostly) work, but there was
one gotcha on a machine going from 7 to 9 that required fallback
and consultation with sun support to make it work.

If you're going to use LU on important servers, I strongly
suggest you break your OS disk mirrors and then do the LU on one
side of the mirror so, if something goes wrong, you have a
fallback to production while you figure out what went wrong.
