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 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 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.
