Hopefully this isn't a rehash of a past thread. I just ordered a 500 GB HD and I plan to use that to replace the hard drive on my new Macbook (Late 2008 model). I've backed up my data using Time Machine. From what I've gathered from various sources, this is my procedure: 1) Replace hard drive. 2) Clean install Leopard. 3) Use Migration Assistant and point it to the Time Machine backup when asked if I want to migrate anything. Am I missing any steps? The only slight confusion is when I will begin to migrate data. Currently, I believe that I do this after Leopard has installed and while I'm setting up the computer (as I did when it first came).
