Red Hat Virtualization Upgrade Overview
This guide explains how to upgrade the following environments to Red Hat Virtualization 4.3 or 4.4 :
- Self-hosted engine, local database: Both the Data Warehouse database and the Manager database are installed on the Manager.
- 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.
For a checklist of upgrade instructions, you can use the RHV Upgrade Helper. This application asks you to fill in a checklist for your upgrade path and current environment, and presents the applicable upgrade steps.
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.
