oldbox# zpool import bigfish

ALL CAPS CAVEAT: before you perform this dance, what version of ZFS and
features does oldbox OI support and what version of ZFS and features
were enabled on newbox's bigfish?

oldbox# zpool get all pond 
newbox# zpool get all bigfish

Assuming oldbox supports all the features of newbox's bigfish pool,
oldbox should be able to import it regardless of the disk device names.
