Upgrade App Volumes Agent Silently

You can also upgrade the App Volumes agent silently using the Microsoft Windows Installer (MSI).

You perform a silent upgrade using the command line and you need not use the App Volumes installer.

For App Volumes agent to validate the App Volumes Manager certificate, you can use the EnforceSSLCertificateValidation parameter.

EnforceSSLCertificateValidation has two values: 0 and 1. By default, the value of this parameter is 1.

• 1 - Certificate validation is activated
• 0 - Certificate validation is deactivated

Note: During the upgrade, if a failure occurs or the upgrade is canceled, the installer for App Volumes agent rolls back to the previously installed version of the agent. After the rollback, the agent virtual machine must be restarted.

Prerequisites

• To ensure that there is no service degradation during the uninstall and subsequent upgrade process, schedule a maintenance window.

• Upgrade the App Volumes Manager.

  See Upgrade App Volumes Manager.

• Unassign all AppStacks from the target computer where you plan to upgrade the agent.

Procedure

1. Open a Windows command prompt on your machine.

2. In the command prompt, access the App Volumes Agent.msi file location.

3. To upgrade the agent, use the following command:

   Option	Description
