How do I move my license to a different domain?
In your WordPress admin on the old website, open the plugin's Account page and click Deactivate License. This frees the activation. Then install the plugin on the new website and enter the same license key when prompted.
If the old site is no longer accessible, log in to https://www.wpwebelite.com/my-account/, open the license, find the old website under its activations and deactivate it from there. If that does not work either, open a support ticket with your license key and the old and new domain names.
