 **Fail-safe upgrade procedure**
-The ansible playbook does **NOT** encode the fail-safe procedure in such a way that it prevents us from skipping versions. It is **mandatory** that we ourselves correctly decide the version to upgrade to.
+Pins ovn-controller version. Then upgrades databases followed by ovn controllers.
+Used to upgrade between non LTS version or from LTS to non LTS etc.
 
-**Is the issue resolved with group.one- prefixes on unit files and /etc/default?**

+**Rolling-upgrade**
+From LTS to the next LTS.
+Upgrades ovn controllers first, then upgrade databases.
 
-It seems to have been fixed using overrides in debian/rules that move stuff to the expected places after building.

-*After testing it looks like this is all done correctly now*
