Hey guys, quick and easy question for one of you I hope. I just got an Install DVD for 10.4 Tiger (I know I know, Leopard in four days, blah blah...) and I want to upgrade to it from 10.3.9. Problem is I just don't know which install option to select -- Should I do 'Upgrade' or 'Archive and Install'? I want to save my two user accounts, network settings, and particularly all my files and documents -- And I know that Archive and Install will do this if I select the preserve option. So what's the difference between this and 'Upgrade'? What am I missing by picking one over the other? I'm just confused is all. Thanks, much love!
