I have server 'A' at a remote site which has a jail 'J1' that happens
to provide an MX service. I have server 'B' on my desk that I need to
configure as duplicate of 'B' including 'J1'. Both hosts are running
FreeBSD-11. We are using EZJail to administer jails on both hosts.
Both hosts 'A' and 'B' and the jail 'J1' use zfs. Zfs snapshots are
regularly taken on 'A' (and 'B' for that matter).

What is the simplest way to move a copy of 'J1' on 'A' to a new jail
on 'B'? I know that it is possible to move zfs snapshots around but I
am rather pressed for time. If someone can provide a reasonably brief
precis of the steps required to move a copy of J1 from A and restore
that as a functioning new J2 on B I then would be much appreciative.
