I'm soon changing my motherboard (and CPU and RAM btw.) from Asrock J5005-ITX to the new one with Intel's B660 chip. I have Ubuntu Server booting root from ZFS pool.

How should I prepare for the migration? What should I double check before and should I expect any particular issues that I should prepare solutions for in advance?

From what I have been reading such hardware migrations are mostly safe but I haven't found much info on migrations particularly with system booting from ZFS.

The system originally was Ubuntu Server 18.04 with ZFS pool configured using this guide https://openzfs.github.io/openzfs-docs/Getting%20Started/Ubuntu/Ubuntu%2018.04%20Root%20on%20ZFS.html but now it is upgraded to 21.10 for highest compatibility possible with Alder Lake stuff.

I'm guessing here, as I have not gone through the process myself.

As long as you don't have full encryption, which might rely on your hardware TPM, you should be safe.

A way to test it would be to connect your harddrives to a live OS (booting from USB) running on a different machine and attempt to import the pool. If that works, ZFS has no ties to your motherboard.

One thing you might encounter though are hardware compatibility issues in the boot process, here you'll need more seasoned Ubuntu users to comment on that aspect.
