I have an interesting situation now. I completed an installation of a Drupal 7.90 website complete with a theme and was in the process of customization when I was persuaded to ditch it and go with Drupal 9. Now I have uploaded via FTP an unzipped distribution of Drupal 9.4.1 thinking I could just over-write the existing code and folder content. But, no. When I load the new index.php in my browser expecting to go through the new steps of installing the new Drupal, it says, "The website encountered an unexpected error. Please try again later.". So what files and folders do I need to delete and what steps do I need to do to essentially uninstall the previous version of Drupal?
