I think I will follow your advice and pull the pool disks until the OS is re-installed, I guess you can never be too careful :) Once the system is on a ZFS root I will be confident to perform future upgrades with the live upgrade tools as I've tried that both on UFS and ZFS and the latter is a hundred times easier.
