I currently have a Macbook Pro (early 2011) with a Kingston 256GB SSD and 2011 Mac Mini with the original 320GB HDD. Now I want to move the Kingston SSD to the Mini and put in a 512GB SSD (Crucial MX100) in the Macbook Pro. How do I go about the easiest way to switch these disks. I want to use time machine since I've setup both systems with a lot of settings I don't want to re-do. I've also only got one external HDD at the moment so I would like to have both time machine copys on the same disk if thats possible. The Macbook runs Yosemite while the Mini runs Mavericks. Any advice?
