How to make a change that affect several site at once? We have two Drupal 7 and two Drupal 8 website for an airline company. We want the staff at the airport to upload a flight schedule in such a way that it will get displayed in all the four sites at once. How can I achieve this?
You should be able to do this by uploading the schedule to one site and then exposing an RSS feed for the other sites to pull it down.
