I have read about the planned release date of Drupal 9 is scheduled to be on June 3rd, 2020. I read this documentation about how to prepare a Drupal 8 site for Drupal 9:
In the document it says:
"1. Keep Drupal core up to date. Drupal 8's last minor release will become Drupal 9."
Does it mean that when we update the Drupal 8 core to the last minor release of Drupal 8, it will automatically convert our site to use Drupal 9 and we don't have to radically change, migrate or redevelop our sites again in Drupal 9?
In summary, is Drupal 8 core's last minor release = Drupal 9?
