I'm not sure, but I think that you can using the hard drive transfer kit, which u plug one end into your hardrive, and the other end into another xbox 360. It has a link to how to do hard drive transfers on the page for the new xbox 360 "slim"http://www.xbox.com/en-US/hardware/x/xbox360250GBconsole/ slim product pagehttp://www.xbox.com/en-US/live/transfer/default.htm transfer info

You are right, the harddrives are not compatible and neither are the memory cards.You can use the HD transfer kit OR a USB drive to move all your info from your old 360 to the Slim.update: http://kotaku.com/5563448/how-to-transfe…
