I've been using TrueNAS for the past couple of months and I quite like it. I am already thinking of upgrading it - sort of. The current boot drive is a PNY 120GB SSD, which seems a waste of capacity; at least it was cheap. The plan is to replace it with two InnoDisk SATA DOMs, 16GB each, and use the 120GB SSD to replace the spinning drive of an old laptop.
I assume the traditional way is to save the current config, reinstall TrueNAS from scratch using the installation media, then restore the previous configuration.
But I would like to try something else:

But I would like to try something else:
- Shut down the server, install both SATA DOMs, then power up the server.
- Create a mirrored configuration by attaching to the boot pool as a member, one of the two SATA DOMs.
- make sure the SSD is mirrored to the SATA DOM.
- Replace the the old SSD in the boot pool with the second SATA DOM.
- make sure the SATA DOM which was first attached to the boot pool is mirrored to the second SATA DOM.
- Shut down the server, remove the old SSD, power up the server.
