Recommended way of transferring an 𝚒𝚘𝚌𝚊𝚐𝚎 jail from one host to another

Source: iocage thick jail running on FreeBSD-12.0p12.
Destination: FreeBSD-12.1p1.

Both hosts use ZFS.

What is the recommended method to transfer an existing iocage thick jail from the source to the destination? Is it as simple as:

rsync -aqz -e "ssh -o LogLevel=error"  /zroot/iocage/jails/testjail \                           destination:/zroot/iocage/jails

Presuming that iocage is installed on both hosts, that the ZFS mount points are as indicated above, that the source jail is shutdown, and that testjail does not exist on the destination host.
