In the 'Displays' System Preferences panel you can drag the menu bar to the other screen. I believe this makes it your main monitor, but my external display is in my office so I can't test it at the moment.

In the display arrangement window, you need to drag the menu bar looking white box across to the other display. Hope that helps!
