Currently using the stock HDD in my new MBP, running Lion - set up with my apps etc exactly how I want it. Only set up a week ago. My Samsung 830 256GB is on order, but hasn't arrived yet. I'm in no hurry etc to upgrade to ML, and am still waiting for my download code anyways. Ultimately I want to be running ML on my SSD with all my current apps and settings etc. I'm good with several backups etc so will ignore that for now as I'll be creating plenty at each step. How does this sound: 1. Update my current HDD to ML. Check everything works. 2. Create a fresh Time Machine backup. 3. Install the SSD. 4. Install Lion (since that's what the MBP originally came with) 5. Upgrade the fresh Lion install to ML. 6. Now that the OS version etc is the same as my Time Machine backup, use Migration Assistant to restore all my settings and applications. Can anyone foresee any issues with this?
