10. After you verify that the new license server is functioning correctly, deactivate the old license server. To do this, uninstall the Terminal Services Licensing component on the old server.

Backup and license information

You should regularly back up the Terminal Services license server by using Windows Backup or a similar tool. Regular backups help protect your licensing data from accidental loss if the system experiences hardware or storage failure. When you back up a Terminal Services license server, back up both the system state data and the folder in which the Terminal Services license server is installed. By doing this, you make sure that data in both the registry and the Terminal Services license server database is backed up.

If you restore the system state data and the database to the original Terminal Services license server, any unissued licenses are restored correctly, assuming you have not replaced the operating system on the computer. If you have replaced the operating system, any unissued licenses are not restored, and an event that provides the unissued license count is logged in the System log. You can still restore the unissued licenses by using the telephone activation option in the Terminal Services License Manager tool. To switch to the telephone activation option, right-click the server in Terminal Services License Manager, and then click Properties.
