Hey There,
Thanks for writing in!
You can simply transfer the licenses by visiting the Account section. Just go to Account and then click on Licenses and there you should see your license. Unassign the licenses from the site and your Purchase code will be free to validate to a new domain. For more information, you can walk-through the below guidelines :

If you are transferring the license to your client and they want to have access to the forum, you will need to create thread and send us the following info:
Purchase Code / Themeco License
Username to transfer from
Username to transfer to
We will then forward this to the team that handles licenses.
Thanks for your understanding!
