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 Omnissa App Volumes installer.

EnforceSSLCertificateValidation parameter allows App Volumes agent to validate the App Volumes Manager certificate. This parameter has two values: 0 indicates that certificate validation is deactivated and 1 indicates that certificate validation is activated. By default, the value of this parameter is 1.

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

• If you use an unsupported version of App Volumes, ensure that you are aware of this upgrade requirement.

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

• Upgrade App Volumes Manager

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

  If you are upgrading to a persistent pool deployment, then you need not unassign the application packages. Upgrade occurs even when the application packages are attached to the target computer.

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
   App Volumes 4 Update 1	msiexec.exe /i "App Volumes Agent.msi" /qn MANAGER_ADDR=<Manager_FQDN/IP> MANAGER_PORT=<port> EnforceSSLCertificateValidation=<0or1> Note: The following parameters are optional: MANAGER_ADDR, MANAGER_PORT, and EnforceSSLCertificateValidation. When upgrading from versions earlier than App Volumes 4, version 2406, you cannot set the NONPERSISTENT parameter to 0. For information about this parameter, see [Install App Volumes Agent Silently](InstallAppVolumesAgentSilently.md). When upgrading from App Volumes 4, version 2406 to App Volumes 4, version 2410 and later versions, using this parameter is optional because the parameter value set for upgrade is the same value which is set during installing App Volumes 4, version 2406. If you choose to use this parameter, ensure that the value of this parameter matches with the value used during installation. If you use the `/norestart` flag in the command, ensure that you restart the virtual machine after the command runs. This restart is necessary for the upgrade to complete.
   App Volumes 4	msiexec.exe /i "App Volumes Agent.msi" /qn MANAGER_ADDR=<Manager_FQDN/IP> MANAGER_PORT=<port> EnforceSSLCertificateValidation=<0or1> Note: All parameters are mandatory.
