[Bug 1859649] Re: networking disruption on upgrade from 14.0.0 to 14.0.3

[Slawek Kaplonski]

@Jens: You are right with version numbers. I just added short note about it to release-checklist doc in Neutron: https://review.opendev.org/702822
I hope it will help and we will remember about that in the future.

Bug description:
  Hi,

  Not entirely sure why, but if a cloud has services running these 2
  versions of neutron (2:14.0.3-0ubuntu1~cloud0 and
  2:14.0.0-0ubuntu1.1~cloud0), networking is basically broken until
  everything is running 2:14.0.3-0ubuntu1~cloud0.

  Which causes networking disruption when not all nodes are upgraded at
  the same time.

  Thanks
