Moving terminal license form one server to another without deactivating first one

Hi! What I want to do is to move some terminal licenses (CAL, per device) form one server to another. So at the end I will have two working servers with some terminal licenses. For now the first one has istalled 95 terminal CALs and the second one none. I want to move 10 licenses from the first one to the second one. How to do that?
