Update Site

I have designed new pages for our current site in Dreamweaver. I want to remove the pages we have live currently and put up the new pages. The file is currently on my FTP. How do I go about uploading and switching out the old pages for the new in Dream Host?

If you want to totally replace your site, FTP in and rename your example.com domain folder to example.old and make a new example.com folder so it’s empty. Then upload your new content.
