Switching Ipods?

Im thinking about getting an Ipod Nano Video(the thrid genreation ones). I currently hold an Ipod nano first generation. Would I own to switch everything. Is there any mode to just put my current songs onto the trial one? How would this effect my Ipod? Please anything will help. Thanks

Answers: Everything contained by your iTunes library will sync to your new iPod. && your done.
