its dead easy to do retrospective as well no need to  rebuild or ditch the
pcbsd install method.

X = current boot drive
Y = blank drive
z = zfs partition/slice eg s1d, p3 etc

gpart backup /dev/X | gpart restore /dev/Y

gpart bootcode -b /zfsboot/pmbr -p /zfsboot/(gpt)*zfsboot -i 1 /dev/Y
zpool attach <pool> /dev/Xz /dev/Yz
