Downgrading is always going to be difficult -- there's no backwards
compatibility guarantee for shared libraries, so you'll find that
programs end up arbitrarily failing in the middle of your downgrade process.
If you need to downgrade then the best route is to back up all your
important data and configuration bits, then reinstall the system using
the older version.
Depending on how adventurous you feel, you may be able do chunks of this
manually while booted from a live-CD, which will allow you to preserve
parts of your original system. That, however, is something for experts,
or the brave -- and you can't necessarily do it at all. For instance,
if your ZFS pool has features enabled and in use that aren't known in
the older system, then you have to blow it away and create a brand new
zpool to downgrade.
