Chapter 1. Red Hat Virtualization Upgrade Overview
This guide explains how to upgrade the following environments to Red Hat Virtualization 4.3:
- Standalone manager, local database: Both the Data Warehouse database and the Manager database are installed on the Manager.
- Standalone manager, remote database: Either the Data Warehouse database or the Manager database, or both, are on a separate machine.
- Self-hosted engine, local database: Both the Data Warehouse database and the Manager database are installed on the Manager.
To save time when upgrading a Manager with local databases, use the
ovirt-fast-forward-upgrade supports local database environments only.
Alternatively, you can manually upgrade the Manager. For remote database environments, this path is required.
Plan any necessary downtime in advance. After you update the clusters' compatibility versions during the upgrade, a new hardware configuration is automatically applied to each virtual machine once it reboots. You must reboot any running or suspended VMs as soon as possible to apply the configuration changes.
Select the appropriate instructions for your environment from the following table. If your Manager and host versions differ (if you have previously upgraded the Manager but not the hosts), follow the instructions that match the Manager’s version.
Table 1.1. Supported Upgrade Paths
For interactive upgrade instructions, you can also use the RHV Upgrade Helper available at https://access.redhat.com/labs/rhvupgradehelper/. This application asks you to provide information about your upgrade path and your current environment, and presents the relevant steps for upgrade as well as steps to prevent known issues specific to your upgrade scenario.
