Well, AFAIK, we require config compatibility between subsequent<br>
versions, so there really shouldn't be anything to report. It might be<br>
useful to report, when running the havana tool against an<br>
upgraded-from-grizzly config which things are deprecated though.<br>
<br>
We already test that the config upgrade works in the grenade test in the<br>
gate, so there really shouldn't be any degredation experienced by the<br>
user after an upgrade...<br>
