Hey there @deanfarwood,
You have quite a few options, actually.
You can clone the installation over to the main directory (if you're on cPanel Linux, anyway.) You'd just have to uninstall the current site on that same directory. You would also probably have to do a search and replace to ensure the new site links to the domain. Here are some guides:
You could also use the plethora of backup and duplicator plugins you can find with a simple web search. Just make sure you do your research if you use this method.
You can hire someone to do it for you or contact GoDaddy, who will also do it for a charge.
So, lots of options. You just gotta decide which one is in your budget, time or money, and go for it.
