There are two ways to release the domain.
Right from the extension's panel
If you initially used the extension's license on your test domain and want to change it to the other one, you need to:
- release the license first
- and then insert the license code on new installation (other domain).
To do so:
1. click the "Your license is valid" link in the extension's control panel
2. Select "release license" and click submit
3. License released and you can use the license on other domain
