Several ideas; on one hand, you can use 'zoneadm ready' to mount the zone filesystems in an official manner. You might also unset the 'zoned=on' attribute temporarily and mount the dataset manually (set mountpoint or use 'mount -F zfs pool/... /mnt/...' to maintain legacy mode).

To transfer you'd probably use 'zfs send -R' for recursive (children and snapshots), though you can use rsync if you get the filesystem mounted and the dataset hierarchy recreated by hand - but you'd rarely need that (i.e. large replica over bad link, so zfssend never succeeds).
