Have you considerd using manageBE
this tool you can set up cloned alternative Boot-Environments (BE) so
that you can go back to your old BE if the new one doesn't work.
I'm in the process of upgrading to 9.0 and taking the opportunity of
changing over to ZFS. I needed to re-arrange my filesystem structure to
boot from tank/ROOT/someBEname/ instead of tank/ (and make sure the
mountpoints of any descendent file systems are suitably adjusted) but
it was worth the effort.
I installed 9.0-RC2 from the ISO onto a spare drive so I haven't done an
8 to 9 binary upgrade but I have used freebsd-update to upgrade from
9.0-RC2 to 9.0-RELEASE and that went through without any problems.
