Upgrading from OpenVZ Based on Kernel 3.10 to Virtuozzo 7
---------------------------------------------------------

.. warning:: This procedure cannot be reverted.

.. note:: Upgrading requires an Internet connection to download Virtuozzo 7 packages.

To upgrade a server from OpenVZ based on kernel 3.10 to Virtuozzo 7:

1. Run the upgrade script:

   ::

       # do-upgrade-vz7 --key <VZ7_product_key>

   In the process, the commercial Virtuozzo 7 packages will be downloaded and installed on your server.

   .. note:: To skip license installation, use ``--skip-license`` instead of ``--key <VZ7_product_key>``. In this case, you will need to install a license later with the ``vzlicload`` tool.

2. Reboot the server.
