I just did the same thing a week ago. But, I've always believed a clean install was the best way. But, if you want to transfer the os to the new drive, the fastest and most fool proof way is to use Paragon Migrate
. It isn't free ($19.95), but it is fast and will transfer the OS, align and format the SSD for you. Transferring the OS to an SSD is what it was made for. I have used it on numerous occasions and it has never failed me. It will take like 20 minutes and you will be on your new SSD.
There is also a good tutorial
on this site about transferring the OS to an SSD
