License-Change of Ownership, how?!

Dear all,
i have Cubase 6, and I want to sell it. What i need to do? Because, the program is registered on my name, but the new owner would like to register the program in his name. What should I do to make the license transferred to his ownership? After the sale, I want to buy a Cubase7. Please, help me.
Thanks in advance.

Surely you have your reasons, why you want to sell your C6 first, instead of simply updating this version to C7, but basically you unregister your eLicenser in your “mySteinberg” account then the buyer can register it to his name. There is a Steinbreg software resale wizard in the “knowledge base”, link can also be found on several threads here.
