Once installed open Remote Desktop Licensing Manager from Server Manager

 

Add the current server into the Terminal Server License Server group as per below,

Right click on the server name and select Activate Server

Select Next at the Connect Method screen, (Automatic connection (recommended) is the default)

Enter the relevant information (Company Information) then select Next

Proceed to the next page and fill out additional information.

Click Next and the server will activate

Select the checkbox and select the operation system the old licensing server is running.

Enter the license server ID previously copied, Select Next

Tick the checkbox to agree to manually remote the licenses from the source server then select next.

 

If the old licensing Server is running Windows Server 2008 not 2008 R2 you will need the original RDS CAL licenses (Refer to documentation) to apply to the new licensing server as a 2008 server cannot automatically migrate the RDS CAL licenses, only 2008 R2 and above.

If the old licensing Server is running 2008 R2 or above proceed through the wizard to migrate the RDS CAL licenses.

 

After you have verified the licences are activated and functional you can deactivate the old RDS licensing server.

Once deactivated uninstall the RDS licensing role via Server Manager
