I'm looking to replace the 500gb in my MBP 15 with a 1TB soon and I'm wondering what is the best way to migrate? 1. connect and format the new drive with external adapter, then use CarbonCopyCloner (or similar software) to clone the original drive on to the new drive, proceed to install new drive into MBP. 2. install new drive, reinstall OSX, then plug in old drive into an adapter and use Migration assistant to migrate to sort out the rest. which is the most fail safe way to migrate? I dont mind how long it takes, just want a perfect migration.
