6.3. Transferring the License to Another Server¶

In case you need to transfer a license installed on one server to another server, you can do so as described below.

If you have a Virtuozzo Hybrid Server product key:

1. Remove the installed license from the source server with the vzlicload -r <serial> command (the serial is shown in vzlicview output).

2. Install the product key on the destination server:

   # vzlicload -p <product_key>
   

   A new license file will be generated and installed in the /etc/vz/license/ directory on the server.

If you have a Virtuozzo Hybrid Server activation code:

1. Shut down the source server or remove the installed license from it with the vzlicload -r <serial> command (the serial is shown in vzlicview output).

2. Make sure that the destination server is up, connected to the Internet, and has at least one public IPv4 address.

3. On the destination server, run

   # vzlicupdate -t -a <activation_code>
   

   When executed, vzlicupdate sends the activation code to the KA server. The KA server verifies the code, generates a new license file, sends it back, and the license file is installed on the server automatically.

4. To check that the license transfer has been successful, run vzlicview. The information about the newly installed license should be displayed.
