There is two way to do that.
First Way:
1. First log in to your current domain admin and to go “Appearance => Theme License” and in License Action click on the “Deactivate License” button.
2. Log in to your New domain and then go to “Appearance => Theme License” and add the license key there.

Second Way:
1. Log in to My account on our site at https://themepalace.com/my-account/ and then click on “View Licenses”, after that click on “Manage Sites” and finally click on “Deactivate Site”.
2. Log in to your New domain and then go to “Appearance => Theme License” and add the license key there.
