This post will help you understand how to redirect WordPress pages and posts when you simply change the TLD of your site in the database without actually redirecting between two site instances with two different TLDs. There should be no reason to launch an entirely new site on a new instance at your host, when you can simply use the Page Rules setting in Cloudflare to manage one to one redirects from the old TLD extension to the new TLD extension for the same domain name.
