AppDynamics licenses for on-premises Controllers are tied to the MAC address of the machine on which the Controller is installed. In rare cases, you may need to move the Controller and its license to a new machine. In this event, you can update the MAC Address associated with your license on your subscription page on appdynamics.com.
Update MAC Address
If you have an on-premises paid permanent license, you can see the Manage MAC Address tab on your subscription page:
The Primary User for the license in the account can see both Edit and History action links. If you are logged in to the portal as an additional contact, only the History action is available.
To change the MAC address for the license, click the Edit link. The Edit Mac Address window appears:
Change the MAC Address and Save.
It is important to note that the MAC Address can be changed up to 3 times within a 12-month period. You need to contact your Account Owner if you have to change it again.
The History action link shows you a history of past MAC Address updates for the license.
