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 such an event, you can update the MAC address associated with your license.
All license users for your account’s license will be able to view, download, and edit the MAC Address for any active licenses. The MAC Address is visible to them on the Company Overview screen.
It is important to note that the MAC Address can be changed up to 12 times within a 12-month period. If you need to change it more often than that, you’ll need to contact the AppDynamics Licensing Team by emailing licensing-help@appdynamics.com.
