I just recently installed a SSD into my 13" Early 2011 MBP. I have upgraded to the 15" Late 2011 MBP and I wanted to know if I could take out my SSD from my 13" into my 15". Is it that simple to just do that? Would it work? I read a few articles stating if it has been the new MBP 2012, the drivers and graphics wouldn't be compatible. Theoretically, I think it would work but I don't want to try and mess anything up. Also, would my old HDD from my 13" (320GB Transcend) work in my 15" MBP if I was to just plug it in? Thanks for any info in advance.
