Most SSD's include Acronis , I cloned my RAID 0 array to my Intel SSD using it without a problem. If your Windows install is old, as in it has alot of installs and uninstalls with unused apps, It wouldn't hurt to reinstall freash.
Cloning is fast and your computer will be just as it was before, a freash install might free up some valuable SSD space by getting rid of unused stuff cluttering up your system, and fix Registry errors windows might have from several updates, It's really up to you.
