Hello!
I'm experiencing some kind of a bug, when I have a controller with
mitaka and a controller with Newton.
When I upgraded the first part of my cluster to Newton, the second part
stopped to work (nova-api).
I got this error:
oslo_service.service ServiceTooOld: This service is older (v9) than the
minimum (v15) version of the rest of the deployment. Unable to continue.
So, as we can see, all those dialogs, manuals, docs, posts which are
talking about compatibility between 2 releases are wrong, aren't they?
I will be happy to read some thoughts from you guys, thanks!
How to reproduce:
Install nova 13 on 2 nodes
Disable the first node
Upgrade the first node to nova 14
Restart nova-api on the second node (13 ver.)

Evgeniy Ivanov
