How to publish a new site in place of existing site?
I have an existing published site (site-A), but I wasn't satisfied with the design. So I duplicated it (which created site-B) to edit it to my liking, because I didn't want to loose the data from site-A yet until I was finished with the new design.
Now I have finished the work on site-B. I want to unpublish site-A and publish site-B on the same domain and subscription. But it appears my subscription is linked to site-A and not to my account as a whole… so how do I publish site-B?
