Dear Experts! I have a MacBook Pro 13" Late 2013 with 512SSD. Recently, I have got a MacBook Pro 13" Early 2015 with 256SSD. I want to upgrade the "256SSD" of my new Early 2015 with the previous 512SSD i have from Late 2013 ". Here's the SSD i have, Early 2013 512SSD, S/N: MZ-JPU512T/0A6 I saw the SSDs have similar pins, also i googled about it then some pages said they are compatible, and some said they are not due to some PCIx2.0 or PCIx3.0 version. I could have just tested them, but i don't want to damage anything. So i need an expert opinion before i do so. Can i do this upgrade ?? I would appreciate any help on this. Thank you in advance.
