Let's get ready for D8 - Migrating Drupal Themes

Migrating websites to Drupal 8 is just here and everyone will need to go through the upgrade cycle which is not straight forward most of the time. Even though there are efforts underway to create a Drupal 8 theme based on one from Drupal 7, but there will still be a need for some work in converting or replacing the theme with a new design when migrating to Drupal 8. Design elements such as images, color schemes and some css may be reused in Drupal 8 in order to reduce upgrade efforts. 


Drupal 8 theme has changed to the core and uses twig template PHP engine which is used in several PHP-based CMS frameworks instead of the custom templating engine utilized by Drupal 7.
