An environment Serial Number is based on the hardware of the server with the controller role for that environment. Changing the hardware of that server, changes the environment Serial Number, making your license invalid. Changing the server with the controller role, can also make your license invalid.
If this happens, you'll need to obtain a new license from the Licensing portal by following these steps:
- find and release the previous environment in licensing; and
- register the environment using the new serial number
If you need any assistance with this process, contact support. To speed up the process specify both your Activation code, the new Serial Number of the environment, and the Service Center version. When you receive a confirmation from the support team, you can download the new licenses for each environment on the Licensing portal.
