An upgrade remediation of a virtual appliance upgrades the entire software stack in the virtual appliance, including the operating system and applications. To upgrade the virtual appliance to the latest released or latest critical version, you can use one of the Update Manager predefined upgrade baselines or create your own.
This workflow describes how to upgrade the virtual appliances in your vSphere inventory. You can upgrade virtual appliances at the folder or datacenter level. You can also upgrade a single virtual appliance. This workflow describes the process to upgrade multiple virtual appliances in a container object.
- (Optional) Create a virtual appliance upgrade baseline.
You create virtual appliance baselines from the Baselines and Groups tab in the Update Manager Administration view. For a detailed description of the procedure, see Create and Edit a Virtual Appliance Upgrade Baseline.
- Attach virtual appliance upgrade baselines to an object containing the virtual appliances that you want to upgrade.
To scan and upgrade virtual appliances, attach your virtual appliance upgrade baselines to a container object containing the virtual appliances that you want to upgrade. The container object can be a folder, vApp, or datacenter. For a detailed description of the procedure, see Attach Baselines and Baseline Groups to Objects.
- Scan the container object.
After you attach the virtual appliance upgrade baselines to the selected container object, you must scan it to view the compliance state of the virtual appliances in the container. You can scan selected objects manually to start the scanning immediately. For detailed instructions on how to scan your virtual appliances manually, see Manually Initiate a Scan of Virtual Machines and Virtual Appliances.
You can also scan the virtual appliances in the container object at a time convenient for you by scheduling a scan task. For more information and detailed instructions about scheduling a scan, see Schedule a Scan.
- Review the scan results displayed in the Update Manager Client Compliance view.
For a detailed procedure about viewing scan results and for more information about compliance states, see Viewing Scan Results and Compliance States for vSphere Objects.
- Remediate the virtual appliances in the container object against the attached virtual appliance upgrade baselines.
If virtual appliances are in a Non-Compliant state, remediate the container object of the virtual appliances to make it compliant with the attached baselines. You can start the remediation process manually or schedule a remediation task. For a detailed description of the procedure, see Remediate Virtual Machines and Virtual Appliances.
Update Manager directs the virtual appliances to download the missing updates and controls the remediation process of when and how to remediate, but the virtual appliance downloads and installs the updates itself.
The remediated virtual appliances become compliant with the attached baselines.
