3.2. Upgrading by Migrating to a New Virtuozzo Storage Cluster

To upgrade by migrating VMs and containers from an old Virtuozzo Storage cluster based on Virtuozzo 6 to a new Virtuozzo Storage cluster based on Virtuozzo 7, do the following:

  1. Update all servers in the cluster based on Virtuozzo 6 to the latest version. You can do this by running yum update on each server.
  2. On a different set of servers, create a new Virtuozzo Storage cluster based on Virtuozzo 7. For instructions, see the Virtuozzo 7 Installation Guide.
  3. Migrate VMs and containers from the old cluster to the new cluster. For more details, see Chapter 4, Migrating VMs and Containers from Virtuozzo 6 to Virtuozzo 7.
  4. 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.
