Hello, I just bought a mcbook pro 15 i7 2.3. It came with mountain lion. Previously, I had a crucial m4 SSD with Snow Leopard on it. I would like to install the SSD in place of the stock HD. Question : How can I transfer my Mountain lion on the SSD without loosing all my data. Can I just "upgrade" snow leopard to M-Lion from the copy installed on the stock HD ? Thanks for your help. Vincent.
