So, as far a I understand for resolving this bug the following is OK :
Block downgrading if there are Hosts or Networks (other than the
default management network) or SD in the DC when downgrading.
Why does having hosts should prevent us from downgrading the DC level?
tomorrow you may have hosts which won't support an older cluster.
Host are associated with a cluster, how can downgrading of DC level
impact the existing hosts? DC downgrade does not downgrade the clusters
level.
well, you are kind of explaining why this can't happen...
a DC can only be upgraded if all Clusters have already been upgraded.
hence a DC can only be downgraded if it has no clusters, hence no hosts.
(because to downgrade the DC, the clusters would have to be downgraded
first, and you can't have a cluster lower than the DC...)
