Upgrade of an Oracle VM Server using the Oracle VM Manager Web Interface directly is only supported for upgrades between Oracle VM Server Release 3.3 errata releases. If you are attempting to upgrade an Oracle VM Server from an earlier release, you must perform the necessary preparation described in Section 5.4.1, “Preparing to Upgrade Oracle VM Servers from Release 3.2 or Earlier”, then use the server upgrade script described in Section 5.4.2, “Upgrading Oracle VM Server using the UpgradeServers.py Script”. You may find it useful to use the UpgradeServers.py script to update Oracle VM Server Release 3.3 errata releases as the script contains more error handling and checking than the the method described in this section using the Oracle VM Manager Web Interface.

This section directs you to the location in the Oracle VM documentation that discusses upgrading the Oracle VM Servers in your Oracle VM Release 3.3 environment using a server update repository.

To upgrade Oracle VM Server using a server update repository, you must first set up a Yum repository based on the Oracle VM Release 3.x channel on ULN. When you have created the repository, add the repository to Oracle VM Manager as a server update repository. You then use Oracle VM Manager to perform the upgrades on the Oracle VM Servers. For information on setting up a server update repository and using Oracle VM Manager to perform the upgrade of Oracle VM Servers, see Update Server and Server Update Groups in the Oracle VM Manager User's Guide.

Make sure you do not not use the Oracle VM Server 3.3 Transitional Update Repository to upgrade between Oracle VM Server Release 3.3 errata releases.
