End-of-life means that those who created the software (the Drupal community) will shift focus to newer versions of Drupal, so it will no longer be maintained and supported. There are various risks involved with staying on any platform which has reached end-of-life. Sooner or later, the risks of staying on Drupal 7 will far outweigh the costs of upgrading to a newer version of Drupal. This is the main reason why its end of life has been postponed, and although it currently has been set for 1 November 2023, it won’t be postponed indefinitely.
More than half of all websites on Drupal (900,861) were still on Drupal 7 (458,726 of them) at the beginning of October 2022.
