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.
