Moving WordPress Dev Site to go Live

I am ready to make my WordPress website live. Thank you wpmu! Now that everything is set up, I can do the things that I am best at and that is drawing my cartoons.

I am currently working on the new dev site: and want it to “go live” going directly to .

As you can see: by clicking on it currently goes to an .html site. I want to move the new WordPress site which is now in the directory “root/minihahas/wordpress” on my server; so it directly links to that url. The new path should be: “root/minihahas”. What do I do with all the existing .html files within that directory now associated with the .html site?
