You just need to deactivate the old license and activate it again using HWID of the new iPad.
You have 1 attempt of deactivation for commercial license in the Cabinet on the web-site (MY ACCOUNT section), but if you ran out of deactivation attempts please contact Support Team.

We can also reset your Site license, but you cannot do it in Cabinet yourself.
