I am building a new server and moving unRAID over to it. I was planning to make a note if exactly which drives are acting as data vs parity then just plugging it all in and hoping for the best.

 

I know my VMs will likely need a bit of re-configuring but is there anything else I need to bear in mind. I am moving from a quad core Xeon based Lenovo TS140 to a 14 core Xeon/X99 mobo/64GB ECC custom machine. 

 

Anything else I need to keep in mind? 

I would change the setup on my unRAID so that nothing would autostart-- Array, Dockers and VM's --- as much as you can.  Making a note of all your settings (I have used screen printouts of the various GUI screens in the past) is an excellent idea (an ounce of prevention...) but that should not matter as unRAID 'remembers' disk assignments by the serial number of the disk.  After you have installed everything into the new box, boot from your present Flash Drive.  UnRAid is hardware agnostic as far as the basic NAS part goes.  VM's are often the biggest issue

I've done this recently, I didn't do anything in particular other than stop the array from auto starting. I then moved everything over to the new motherboard/cpu and it just worked. I was moving from a machine 4 onboard SATA connectors and an 8 port SAS card to a new motherboard that has 10 onboard SATA connectoers.

 

I didn't make any particular note of what drives were plugged in where as unraid identifies them by serial number etc.

Great suff, sounds straight forward.
