@satello Hello again.
@Haioken has generously mostly already covered things here but I can chip in a bit also.
If you are also moving over the Rockstor system disk, as well as it’s data drives, then you should be OK, ie the entire system and it’s config should just move over. As @Haioken states, there might be an issue with the network but it has always just picked up where it left off for me. If not then look for duplicate interfaces or the like, the nmcli may help here. But for me moving systems from one machine to another has ‘just worked’ on the network.
Very early Rocsktor did track drives by their temp names, ie /dev/sda etc, but for the last few years we track drives by their serial number, as reported by udev: see:
Device management in Rockstor
“Subtitle: Rockstor’s Serial Obsession”
So you should be OK on that front as they shouldn’t change from one system to anther.
This is true, however it is generated on first boot after install and will then remain stable irrespective of hardware changes there after. However if you then re-install after you have changed motherboard then a new appliance id will be generated. So if one is moving an existing install then no worries on the appliance id as it will move with the system disk and remain the same for the lifetime of that install.
Hope that helps to clarify things.
