What is meant by ‘device’ in terms of the licence? SSD or NAS?

I had to send back the new machine I installed my first ZimaOS+ licence on.

I have the SSD but want to use that now on the replacement machine (an Aoostar Max WTR).

To further complicate matters I used a small 512gb for the install and would like to use a larger SSD.

is the licence tied to the old machine I sent back or the original SSD.

Do I have any options?
