2.1. Upgrading with Spare Virtuozzo 6 Servers

To upgrade by using a spare Virtuozzo 6 server, do the following:

  1. Update both the Virtuozzo 6 server to be upgraded and the spare server to the latest version. You can do this by running yum update on each server.
  2. Back up all VMs and containers on the Virtuozzo 6 server to be upgraded. You can do this with the pbackup tool as described in the Virtuozzo 6 User’s Guide.
  3. Temporarily migrate VMs and containers from the Virtuozzo 6 server to be upgraded to the spare Virtuozzo 6 server. You can do this with the pmigrate tool as described in the Virtuozzo 6 User’s Guide.
  4. Perform a fresh install of Virtuozzo 7 on the Virtuozzo 6 server to be upgraded. For instructions, see the Virtuozzo 7 Installation Guide.
  5. Migrate VMs and containers back to the upgraded server from the spare server. For more details, see Chapter 4, Migrating VMs and Containers from Virtuozzo 6 to Virtuozzo 7.
  6. If you store VM and container backups on a Virtuozzo 6 server, move them to a Virtuozzo 7 server as described in Chapter 5, Restoring Virtuozzo 6 Backups to Virtuozzo 7 Servers.
