You have to load the application files onto your BES and index them so you can see them in BB Manager - which can be installed on a different computer.
Check out this article on how to load applications from the BES - the same procedure applies to OS upgrades. You will need to create a software configuration for the OS. BlackBerry Search Results
Then, using the USB cable, plug the device you want to upgrade into the computer running BB Manager. Go into BB Manager and click on Local Ports. You should see the device. Right click on the device and you will get a menu of what you can do. Caution: I'm not sure if you can do a straight upgrade or if you will need to do a fresh install of the OS on the handheld - which would require reactivation. You will definitely want to test with a spare device and not your users' devices.
