I am planning on a major redo of the website including changes to the home page, sub pages, links, etc. Is there a way to "sandbox" my project so that over a period of time I can make changes and test before I go live? I understand that I can develop a new homepage and see it before I publish it but evidently I cannot test any links from that page. The same applies to sub pages, custom pages and stories. I am concerned that when I try to make some large changes to the site that miss something unrecoverable. Some advice please.
