Quoting Simone Dal Maso simone.dalmaso@juvox.it:
Hi, I have drupal 5.6. Should I upgrade before to drupal 5.7, 5.8 and so on or can I upgrade directly to the last drupal 5 version?
This is asked so often it isn't funny. The real answer is "maybe". You'll have to try 5.6 -> 5.11 and see what breaks for you. Should be a "good to go". However, don't do D5 -> D6 without doing 5.6 -> 5.11 first.
