How do I reissue my license?
The new licensing system does not have the ability to reissue as each installation is registered as an "activation". Let's say you activated a 5-site license on yourdomain.com but now wish to move this installation to yournewdomain.com. To facilitate that move, you will need to log into your account and navigate to "My Services" > "Licenses," and click on "Manage Sites" for the license in question.
Once loaded, you will see all of the domains that are actively using this license. Simply delete yourdomain.com from the list and run your product installation on the new domain name you're moving to. If you have any issues activating your site, please be sure to open a support ticket.
