Returning License Rights to the Server
You might need to return license rights when you add a license server or want to move licenses from one license server to another. The return process is identical to the activation process, the only difference being that the license count is reduced instead of increased. For more information about the activation process, see Activating License Rights on the Server.
The FlexNet License Server Administrator command-line tool supports both an online and an offline return process.
If administrative security is enabled on the license server, you might need to provide authorization credentials to perform operations described in this section. For more information, see Use Credentials to Access Operations.
