This is a notification that the Drupal community will stop releasing updates for Drupal 6 sites about three months after the release of Drupal 8, which is likely to be released in the next year. University IT will continue to test and provide updates to Drupal 6 sites through the upgrade tool as long as the Drupal community releases them. While University IT will not support any new Drupal 6 installs through the Collaboration Tools Installer, University IT will not take down any existing Drupal 6 sites.
University IT strongly recommends upgrading to Drupal 7 soon and not waiting until after Drupal 8 is released. Stanford faculty, staff, and students who are interested in starting a Drupal site are encouraged to use Stanford Sites, a self-service tool for building Drupal 7 websites.
