I am upgrading Drupal 7 to Drupal 9 and trying to copy over my CiviCRM database.
My Drupal 9 install is fresh. I used the instructions at https://docs.civicrm.org/installation/en/latest/drupal8/ to download CiviCRM with Composer.
I have upgraded the existing CiviCRM settings file to work with Drupal 9.
The problem is that I am getting the following error when trying to load Drupal."Warning: require_once(CRM/Core/ClassLoader.php): failed to open stream: No such file or directory in require_once() (line 516 of /home/user/public_html/web/sites/default/civicrm."
As expected Drupal will not load at all.
I have checked all my paths and that CiviCRM is in my vendor folder. /home/user/public_html/vendor/civicrm
Any help is greatly appreciated.
