How do I replace C2 site with Wordpress site?

I've made a temporary website using C2 and I would like to change my site to a Wordpress site.

However, the site keeps loading from the user's cache.

How do I disable the cache to load the new website properly?

I need to automatically route the user to the new website and not ask users to clear their cache manually.

I've tried deleting all the old files, but I still load from my cache.

Thanks.
