3.2. Upgrading to Red Hat Virtualization Manager 4.3 with ovirt-fast-forward-upgrade


  1. Log in to the Manager machine and install the ovirt-fast-forward-upgrade tool:

    # yum install ovirt-fast-forward-upgrade
  2. Run the following command to upgrade the Manager, while creating a backup of the current version:

    # ovirt-fast-forward-upgrade --backup --backup-dir=/backup

    Red Hat recommends using the --backup and --backup-dir options to create a backup of the current Manager. If a backup directory is not specified, the backup is saved in /tmp.

    The --backup option is a wrapper for the engine-backup tool and is equivalent to running the following command:

    # engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name

    To restore your backup, run engine-backup in restore mode:

    # engine-backup --mode=restore

    See Backing Up and Restoring the Red Hat Virtualization Manager in the Administration Guide for details.

    Alternatively, to upgrade without creating a backup, run the following command:

    # ovirt-fast-forward-upgrade
  3. If there are errors, check the log: /var/log/ovirt-engine/ovirt-fast-forward-upgrade.log.

The tool enables the proper repositories and upgrades the Manager to 4.2.

If the tool detects that the cluster compatibility version is set to 3.6 or 4.0, the tool pauses and prompts you to manually upgrade the cluster compatibility version to at least 4.1.


If you try to continue without upgrading the cluster compatibility version to at least 4.1, ovirt-fast-forward-upgrade aborts.

You must now update the hosts before you can update the cluster and data center compatibility versions.
