Buying cubase with licenser

Hi
I may be buying Cubase with elicenser, 2nd hand.
How is this done best for me is a buyer?
Should the seller transfer it first digitally, then send it to me?
Or is it just a matter of “unlinking” the license (seller), and then I enter the license keys when I get the dongle?

Hi,

Follow the How to resell Steinberg software (Resale Wizard) article, please.
