Hi again @SarahOps, I believe there is no “one button” way to clone the whole site, you would need to do it page by page.
Maybe it’s worth to set up a Sandbox account to test everything before release it to production. Here you have more info about it: Create a sandbox and deploy changes to production
Regarding the follow-up question, noindex - nofollow just avoids this page to be indexed, but it won’t prevent any functionality to work. So if you have a form in the page, it will work as it works in the “main” page.
