14.2.4. Upgrading to Red Hat Enterprise Virtualization Manager 3.4

Summary

The following procedure outlines the process for upgrading Red Hat Enterprise Virtualization Manager 3.3 to Red Hat Enterprise Virtualization Manager 3.4. This procedure assumes that the system on which the Manager is installed is subscribed to the channels and entitlements for receiving Red Hat Enterprise Virtualization 3.3 packages at the start of the procedure.

Important

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 3.3 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.
