How to mount a ZFS pool in FreeBSD for cloning

I am in the process of trying to clone a FreeBSD installation onto a new hard drive and need to mount it and then find the mount points in order to proceed with the cloning process. The internal drive that I want to clone to currently has a Windows 10 install and a not very optimised FreeBSD install that I want to clone over. I am happy to use the current UFS partition scheme for the FreeBSD. I will boot from a live FreeBSD USB stick in order to run the appropriate commands. The problem that I am having is that the disk I want to clone from is partitioned using ZFS and I can't get my head round how to mount it and then how to find the mount points. The disk is connected to my computer using a USB-SATA adapter.
