Small Business Website Design

I decided to move my website to a wordpress template. I designed the template and it's ready to go. My website was originally made with dreamweaver, and having little knowledge of web design, I created all 200+ pages using only one template on dreamweaver. So my question is, if I install wordpress on the server where my website is hosted, will all my content get deleted and overridden by wordpress? Or what would be the easiest and most...
