Why upgrade to Drupal 8?

  • Drupal 9 is scheduled to be released in June 2020. However, upgrading from Drupal 8 will not be complex as the last version Drupal 8 will be the same as the first version of Drupal 9, the difference being all deprecated codes will be removed. Migration from Drupal 8 to Drupal 9 will be easier than all previous migration.
  • Drupal 6 is no longer supported. i.e. there will be no further official release.
