Appendix D. Upgrading to Red Hat Virtualization Manager 4.2 with ovirt-fast-forward-upgrade
If you have Red Hat Virtualization 4.0 or later installed, you can upgrade the Manager to the latest version with the ovirt-fast-forward-upgrade tool. ovirt-fast-forward-upgrade detects the current version of the Manager and checks for available upgrades. If an upgrade is available, the tool upgrades the Manager to the next major version, and continues to upgrade the Manager until the latest version is installed.
ovirt-fast-forward-upgrade upgrades the Manager. See Section A.4, “Manually Updating Hosts” to upgrade the hosts.
Upgrading with ovirt-fast-forward-upgrade
Install the
ovirt-fast-forward-upgradetool:# yum install ovirt-fast-forward-upgrade
Run the following command to upgrade the Manager, while creating a backup of the current version:
# ovirt-fast-forward-upgrade --backup --backup-dir=/backupNoteRed Hat recommends using the
--backupand--backup-diroptions to create a backup of the current Manager. If a backup directory is not specified, the backup is saved in/tmp.The
--backupoption is a wrapper for theengine-backuptool 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-backupinrestoremode:# 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

If there are errors, check the log:
