If You first create new ZFS BE and then do the upgrade

inside - I do not see any 'risk' here - You are basically

replacing or extracting new files into that ZFS BE. In

the next step You 'activate' that ZFS BE and reboot into

it. It was possible even with freebsd-update(8) command

as shown for example below and its possible with PKGBASE:

On UFS You can use UFS Boot Environments - they work slightly

different but the end results is mostly the same - even on ARM.
