Hey there, alucardseres!
You have the option to clone your OS to the SSD, and there are quite a lot of software applications just like the one @qazzi suggested, that can do that for you.
I personally like Acronis True Image, you can clone automatically or manually and also select what gets cloned:

Usually, the best-case practices show that performing a clean install on the SSD is the preferred option. This way you are not getting all the junk and redundant files from your previous OS usage. IMO re-installing is much better.
However, if you don't have a factory Windows recovery disk, cloning is the way to do it.
