Prev	Chapter 4. Upgrading Oracle VM	Next

When upgrading Oracle VM, you must upgrade Oracle VM Manager first, then upgrade the Oracle VM Servers managed by Oracle VM Manager. The Oracle VM Manager upgrade is performed with the Oracle VM Manager ISO file/CD or with the patch zip file. The Oracle VM Server upgrade can be performed using either the Oracle VM Server CD, or using Oracle VM Manager from a Yum repository (which you must create) that retrieves the Oracle VM Server updates from the Unbreakable Linux Network (ULN). To access ULN, you need an Oracle Support contract.

Before you begin the Oracle VM Manager upgrade, download the Oracle VM Manager software from the Oracle Software Delivery Cloud at:

If you want to use the Oracle VM Server CD upgrade method, also download the Oracle VM Server software from the Oracle Software Delivery Cloud:

If you have an Oracle Support contract, you can also download Oracle VM Manager patch updates from the My Oracle Support web site at:

https://support.oracle.com

The process you should follow when upgrading Oracle VM is described in a high level view below. More detailed information is available in the sections that follow.

To upgrade Oracle VM:

Download the Oracle VM software.
To upgrade Oracle VM Manager:
1. If you downloaded the Oracle VM Manager ISO file from the Oracle Software Delivery Cloud, mount the Oracle VM Manager ISO file or burn and load the CD on the Oracle VM Manager host computer. If you downloaded an Oracle VM Manager patch file from My Oracle Support, extract the zip file to a directory on the Oracle VM Manager host computer.
2. On the Oracle VM Manager host computer, run the runUpgrade.sh script from the mounted Oracle VM Manager ISO file/CD or directory to upgrade Oracle VM Manager.
To upgrade Oracle VM Server, either:
- Set up a Yum repository which retrieves updates from the Oracle VM 3.x channel on ULN. Then, from Oracle VM Manager: add the Yum repository, place each Oracle VM Server into maintenance mode and update each Oracle VM Server. When the update is complete, take each Oracle VM Server out of maintenance mode. This is the preferred method of upgrading Oracle VM Servers.
- Burn the Oracle VM Server ISO file to a bootable CD. Upgrade each Oracle VM Server using the Oracle VM Server CD.

The following sections discuss these steps in more detail.

Caution

When Oracle VM Manager is upgraded, you must upgrade all the Oracle VM Servers managed by that instance of Oracle VM Manager before you can return the Oracle VM environment to normal operation. Rolling upgrades of the Oracle VM Servers is supported, but Oracle VM Manager and all Oracle VM Servers must be at the same software revision level during normal operation of the Oracle VM environment, for example, Oracle VM Manager and all Oracle VM Servers should be running Oracle VM Release 3.1.1.
