DS1812+ died, easy replacement?

My loyal DS1812+ dropped off the network yesterday and when I went to check on it, the unit will not power on. Assuming it’s either the power supply or motherboard, I don’t see it’s worth repairing an almost 10 year old unit that has reached EOL.

If I buy a new DS1821+, can I just pull the disks from the old unit and put them in the new one? Given it’s an Intel to Ryzen switch, how do I load DSM without damaging the existing data volumes?

Thanks in advance.
