Did just that with no kinks at all. It's a zfsroot system with
gptzfsloader. Had to upgrade the gpt bootcode as instructed when
upgrading the zpool for the system to boot. Installing misc/compat8x
made the ports upgrade a lot smoother.

Also had to manually fetch source.txz and extract into /usr/src/sys in
order for certain ports to build correctly such as x11/nvidia-driver,
as that was not done by freebsd-update
