Drupal has been a long-term ally for those in the CMS world both on the development and consumer sides. Drupal 7 first emerged in January 2011, Drupal 8 in November 2015 and Drupal 9 in June 2020. Typically when a new major version comes out, there's a pattern of deprecation that happens in various forms for the previous versions already available. In the case of Drupal 9, this means that Drupal 7 and 8 will reach end-of-life at the same time, in November 2021. This has given cause for concern and questions for those with websites built on those older versions of Drupal.
