⁠6.2.3. Upgrading to Red Hat Enterprise Virtualization Manager 3.3

Prerequisites:

Section 6.3.1, “Upgrading to Red Hat Enterprise Virtualization Manager 3.2”

Summary

The following procedure outlines the process for upgrading Red Hat Enterprise Virtualization Manager 3.2 to Red Hat Enterprise Virtualization Manager 3.3. This procedure assumes that the system on which the Manager is hosted is subscribed to the channels and entitlements for receiving Red Hat Enterprise Virtualization 3.2 packages.

If the upgrade fails, the engine-setup command will attempt to roll your Red Hat Enterprise Virtualization Manager installation back to its previous state. For this reason, the channels required by Red Hat Enterprise Virtualization 3.2 must not be removed until after the upgrade is complete as outlined below. If the upgrade fails, detailed instructions display that explain how to restore your installation.

Procedure 6.7. Upgrading to Red Hat Enterprise Virtualization Manager 3.3

Subscribe the system to the required channels and entitlements for receiving Red Hat Enterprise Virtualization Manager 3.3 packages.
Subscription Manager
Red Hat Enterprise Virtualization 3.3 packages are provided by the rhel-6-server-rhevm-3.3-rpms repository associated with the Red Hat Enterprise Virtualization entitlement. Use the yum-config-manager command to enable the repository in your yum configuration.
```
# yum-config-manager --enable rhel-6-server-rhevm-3.3-rpms
```
Red Hat Network Classic
The Red Hat Enterprise Virtualization 3.3 packages are provided by the Red Hat Enterprise Virtualization Manager (v.3.3 x86_64) channel, also referred to as rhel-x86_64-server-6-rhevm-3.3 in Red Hat Network Classic. Use the rhn-channel command or the Red Hat Network web interface to subscribe to the Red Hat Enterprise Virtualization Manager (v.3.3 x86_64) channel:
```
# rhn-channel --add --channel=rhel-x86_64-server-6-rhevm-3.3
```
Update the rhevm-setup package to ensure you have the most recent version of engine-setup.
