Changing boot pool

[frankit2000]

Hi folks,
I've a TrueNAS-12.0-U8 server on ada0 - 238.47 GiB boot-pool.
The four MB SATA input are used (one) by the boot-pool and (two) by a data pool. The last one is free.
MB has a SSD M.2 connection and I would boot the system from ada0 to a SSD M.2 (to get free two SATA input for a new data pool). I tryed to raw copy ada0 on a SSD M2. (Truenas shell: dd if=/dev/ada0 of=/dev/the_M2) and I've changed boot order in BIOS, but Truenas don't boot correctly. Any suggestion?
Thanks.
Francesco

PS: sorry for my "raw" english!

Just save your config, install a new copy to the desired disk, boot it and upload your config.

alternatively, you could have just...mirrored the boot to the new drive, and then dettached the old drive, making sure to update your boot order so that it will boot correctly.
