How to Upgrade the Servers and System Components
Use the following procedure to upgrade software components installed on all Application Virtualization System computers. Application Virtualization System services will be restarted automatically on each computer after it has been upgraded.
Note
The upgrade process stops all Application Virtualization System services, thereby taking the system out of service. User sessions should be shut down before you begin the upgrade process, and you should stop all Application Virtualization Server services in your environment.
If you have more than one server that is sharing access to the Application Virtualization database, all those servers must be taken offline while the database is being upgraded. You should follow your normal business practices for the database upgrade, but it is highly advisable that you test the database upgrade by using a backup copy of the database first on a test server. Then, you should select one of the servers for the first upgrade, which will upgrade the database schema. After the production database has been successfully upgraded, you can upgrade the other servers.
You can upgrade to Microsoft Application Virtualization (App-V) 4.5 only from Microsoft Application Virtualization (App-V) 4.1 or 4.1 SP1. App-V 4.0 and earlier must be uninstalled or upgraded to 4.1 or 4.1 SP1 before upgrading to App-V 4.5.
