Questions about migrating a ZFS RAID (lemmy.world)

I've recently been looking at options to upgrade (completely replace) my current NAS, as it's currently more than a little bit jank and frankly kinda garbage. I have a few questions about that and about migrating my current TrueNAS scale installation or at least it's settings over.

Q1: Does the physical order of the drives matter? I.E. The order they are plugged into the SATA ports.

Q2: Since I have TrueNAS scale installed on a USB flash drive (yeah, ik you're not supposed to but it is what it is), how bad of an idea would it be to just... unplug it from my current NAS and plug it into the new one?

Q3: If all else fails, how reliable is TrueNAS scale's importing of ZFS Pools and are there any gotchas with it?

Q4: Would moving to a virtualized solution like proxmox and installing TrueNAS scale on top of that in a VM make more sense on a beefier server?

E: Thank you all for the replies, the migration went smoothly :)

Don't try to move TrueNAS to a new host. That's not going to work well. You should setup the new NAS and then do a ZFS send and receive to move data.

If you are reusing the disks you can just export and then import the pool.
