Hi. Going from a Late 08 Unibody MBP 15 2.53 w/ Snow Leopard to a June 09 Unibody MBP 15 2.8. I'm planning to literally just put my old hard drive (SSD) into the new laptop. Will that cause any problems does anyone know? Other than the processor and some motherboard changes, the computers are basically the same, so it would seem to be a non-issue other than the extra difficulty of opening up the newer cases. Thoughts? Thanks!
