If you need to move a page from the documentation you need to think about the people who bookmarked it and about search engines. As much as possible, make sure URLs are preserved.
You can use the following hugo configuration to create a redirection:
---
layout: redirect
redirect: https://www.newsite.org/new_location
_build:
list: never
---
See example PR
You can use Hugo aliases to preserve URLs
---
title: ...
aliases:
- /previous-url
---
