Hey, so I created a site using one of the awesome RT templates, but its time for an update and I want to use a different RT template. How do I go about editing a new theme, testing it, etc on the server and eventually replace the old theme? I need the old/current one to stay live while I complete the new one, but I also need to see what the new one looks like live too.
This was a very difficult topic to Google or search the archive. Maybe a link to it on one of the pages?
