I would recommend you take a look at the Software Upgrade guide available on Aruba's support website.

My only addition to that is to remember that the Aruba 200 controller has a light weight processor. Patience is a virtue when doing the upgrade and do not unplug the controller until it has completed. You could corrupt the image with a premature hard reset by unplugging the unit.

I agree with the other reply that the easiest way to upgrade is through the GUI (although I always use and teach students to use FTP from the CLI, what can I say, I'm old school).
If you're not sure what version, from the CLI "show image version" will show both OS partitions and which one you are currently booting from.
