  Configuration for `authorization_scopes` will no longer be supported. Use default_scopes/optional_scopes instead.
  ATTENTION: The :description option could not be migrated because doorkeeper now uses localization files.
  Place this in your config/locales/en.yml

  In order to use the Client Credentials flow, you have to migrate the oauth_access_tokens table:
