If you have root on ZFS, you can shuffle your directories around to get
something compatible with beadm [1] . With that in place, you could clone
your existing install, chroot into it, do the upgrade there, and then if it
looks like it should work you can activate it and reboot to test.

If it fails, you should be able to re-activate the previously working
environment (by setting vfs.root.mountfrom to the appropriate path in the
loader, I think) and be back where you were without too much fuss.

With the caveat that I've barely touched this myself.
