If you want to use Social Rocket Pro or its extensions on a different domain, you are certainly welcome to do so.
If you still have access to the old licensed site, navigate to Social Rocket > License Keys and click the Deactivate License button next to each license you wish to move. You can then install the extensions on your new site.
If you no longer have access to the old site, no worries! Log into your account and navigate to the License Keys tab, then click Manage Sites. On the next screen, you’ll be able to remove or deactivate keys from there to free them up for use on the new site.
