We update websites to Drupal 9 and migrate existing content.
Upgrading to higher versions of Drupal with Migrate API
Drupal is constantly evolving and it is essential to be prepared for change. From the versions we started working with (Drupal 5) to the current ones (Drupal 9) there are numerous changes that sometimes make the updates a complex process.
In Metadrop we prepare the websites so that the update has the least impact possible and we have experience choosing the right approach and tools, such as the use of drush and plugins for multilingual sites.
