On encrypted ZFS?  I'm not sure there is a brute-force way that is 
trustworthy.  Using higher-level commands to recreate the partitions, 
GELI encryption, and then zfs send | recv are certain safer and won't 
duplicate supposedly unique IDs.

Provided the binaries have not been optimized for one CPU, just move the 
drive.  Disk drive names can change, which is not a problem when labels 
are used.  Ethernet interface names can change.  If there is only one 
interface, use ifconfig_DEFAULT in /etc/rc.conf.
