Hey y'all, Recently made the decision and took the plunge on upgrading my MBP with an SSD. I've seen plenty of resources on the Hardware Installation process and I am not worried about properly installing the hardware, I've seen a bunch of exhaustive guides out there. I am more concerned about the software side of things and making sure my data is migrated properly. I've done a few hours research already and can't seem to find answers to my exact situation so I thought I would turn to you folks. Already have my 120GB 840 EVO ready and now just awaiting for my Data Doubler to arrive. Will be installing it in the main bay and moving my stock 500GB HHD to the optical bay. I plan to have just OS and my apps on the SSD and keep my other documents and media on the HDD. After I complete the hardware installation, is there anyway to just transfer the OS and apps from the HDD onto the SSD and how would I go about that? It that a bad idea, will it mess up the directories on the OS? As much as possible I would really want to avoid reinstalling the OS and all my apps onto the SSD to save the time and hassle. If it makes a difference, I also have a 500GB external HD if it'll be of use. Is there anything I am missing or are there gaps in my understanding on how to create this setup?
