A QE review should be performed on the new updated guide to make sure that it meets the necessary requirements:

• The steps have been tested and are confirmed to work.
• The guide does not contain steps that are unnecessary or obsolete in the latest version.
• The guide documents a recommended, user-friendly path. 

One of the things we need to resolve is whether the step to delete discovered hosts is still required or is now obsolete, see also https://github.com/theforeman/foreman-documentation/pull/3867#discussion_r2099689161 Resolved now, more details in the thread on github.
