Chapter 1: Updating the oVirt Environment

oVirt Upgrade Overview

This guide explains how to upgrade your current environment to 4.2. Two upgrade paths are documented here:

  • Local Database: Both Data Warehouse and the Manager database are installed on the Manager.

  • Remote Database: Data Warehouse is on a separate machine.

To upgrade a self-hosted engine, see “Upgrading a Self-Hosted Engine Environment” in the Self-Hosted Engine Guide.

Select the appropriate instructions for your environment from the following table. Note that the source version refers to the Engine version. If your Engine and host versions differ (if you have previously upgraded the Engine but not the hosts), follow the instructions that match the Engine’s version.
