how delete boot-pool?

[McFuddy]

So I have a box TN box I put together to learn TN on and one of the questions I have is how to delete a boot-pool?
I had two 2tb drives and experimented with creating a boot disk/pool and viola! I did (I think). But I want to eventually put the boot drive (not nessisarily a pool as the boot disk can easily be backed up?) on a smaller, likely NVME, drive. What is the best way to either delete or reassign these two drives once I get the nvme and am ready to install TN on the NVME?
Thanks!

1. Save your configuration.
2. Boot from a FreeBSD 13.1 image on a USB drive.
3. Select "live" or "shell" don't remember from the top of my head.
4. Use the zpool labelclear command on your NVMe drives.
5. Boot from a TrueNAS install medium and do a fresh installation to your smaller drive.
6. Reimport saved configuration.
