How to upgrade to Drupal 8 from 7 with clean install? I currently have a Drupal 7 site that I want to install Drupal 8, but do a clean install. This means wiping away everything and starting with a new Drupal 8 instance. I have seen many articles on how to upgrade where the content types, fields, code, and other parts are migrated. However, I just want to upgrade to Drupal 8 without any migration of the content type, files, databases, and remove old directories that are not needed for Drupal 8. 

How can I upgrade to Drupal 8 without any migration for a clean instance?
If I'm understanding your situation correctly in that you just want a new Drupal 8 website without any of the content from your existing Drupal 7 website then you would just simply install Drupal 8 from scratch, as if you didn't even have an old site.

Once the new Drupal 8 website is installed you can then create/re-create any content that you'd like.
