buying 2nd hands Sophos Endpoint licenses

Hi all,

Simple question, is it possible to buy licenses previously sold to somebody else?

Let's say somebody bought licenses valid for SEP Advanced / 3years and stopped activites and is
now selling the remaing licensed time period for the product.

If it is possible, how easy it is to transfer the licenses from old owner to new owner ?

Thanks in advance,

best regards,
