I have an old 15" MBP (2009) that the screen went out of and I decided, for the price, to buy a brand new (2012) 13" MBP. I want to get all of my stuff from my old computer onto my new one but can't see the screen or even get anything from the Mini DisplayPort to a TV, so can I take the old HDD out and plug it into my new computer after backing up this HDD? Then with the old one in here, back up to my external and switch everything back over to current settings?
