I would do a fresh install. Just my preference. You may or may not have to re activate windows. They will give you a 1-800 number to call and you just enter a key into an automated system. It only takes a few minutes super easy. My first 2 re installs and component swaps I didn't have to re activate but every time after that I have.
COngrats for making the switch :D Once you go black you never go back
and by black I mean SSD ahahahaha
