Hi, I have an old Mac Mini Server (Mid 2010) that I haven't used in years and would like to upgrade from stock Snow Leopard to at least Lion for iTunes/iPhone backup limitation. I would like to use as workstation and convert mirror drives to two separate drives so I can install Windows XP on one drive and newer OSX on the other. How do I do this? Any major limitations? This will not be used as main system, just back up to an iMac that's happily running Snow Leopard but cannot backup iPhone due to old vs of iTunes. I also plan to upgrade memory to 8/16.
