You can also upgrade the App Volumes agent silently using the Microsoft Windows Installer (MSI). If your current installed version is App Volumes 2.12, you do not need to uninstall it before upgrading.
You perform a silent upgrade using the command line and you do not need to use the App Volumes installer.
Prerequisites
Schedule a maintenance window to ensure that there is no service degradation during the uninstall and subsequent upgrade process.
Upgrade the App Volumes Manager. See Upgrade App Volumes Manager.
Unassign all AppStacks from the target computer where you plan to upgrade the agent.
