I'd like to upgrade my "C" system drive -148GB SSD- to a 256GB SSD, seamlessly if possible. The C drive is for Win7-64bit, and many installed programs. I have Acronis, but the instructions are a bit obscure and don't answer several questions. Would Paragon work?? Any other ideas? A clean install is out of the question, I've moved several times and don't have all the discs.
