Replacing old SSD Boot drive with better one. Help

Hi guys, 

Last Septemember I built my computer, and the only thing I would have done differently is gotten a bigger SSD! At the last second I switched from a 120 gig to a 60 gig to save money. That was a big mistake.

 

Anyway, I currently have pretty much just my OS on it, some programs and other random things. How do I install the new one without losing everything on the current one? My plan was to replace the current 60 gig (Drive C:) With the new one, and then just using the 60 gig as a back up drive or for throwing my files onto it when I render. 

 

So how do I go about this? Thanks guys.

I've never done this but I think http://www.clonezilla.org/ is a good place to start? 

Maybe someone else with more expertise can help!
