Remove the domaine on

Hi, I was going through the steps of creating an LLC in the US for my project, I am forced to change the Site Name, also the domain name, I had already installed the plugin on a domain name (myrgue.com) I had planned to use, but now I am not going to use it anymore, I want to reset it before reinstalling it to avoid any problem with my license, please can you reset my license for me?

Thank you!

Old Domaine name: myrgue.com
New Domaine Name: tredihshop.com
