I have a late-2006 C2D MacBook with a 500GB internal drive (running the latest version of 10.6). I'm looking at replacing it with a 13" MB Pro, which comes with a 250GB HD. I want to put my 500GB drive in the Pro while keeping all its contents. Is it possible to just pop the 500GB drive into the new machine? Will there be issues given the differences between the machines?
