Choosing which method to upgrade the client software
You can upgrade the client using multiple ways. The method you should use depends on your environment and goals. For example, you might have a large number of clients or groups, or computers that run different versions of the client.
Some methods can take up to 30 minutes. Therefore, you may want to upgrade client software when most users are not logged on to their computers.
When to use
When not to use

If you upgrade the client on computers with existing managed clients, the clients stay managed. However, if you deploy to new computers without an existing client, this method installs an unmanaged client only. You must convert the client to a managed client later to connect to the management server.
