Eli - just saw this. I'm pretty sure it would be *bad* to downgrade a DC
version if it has storage domains as well. not sure if this is checked
already or not.
may also be an issue with some logical network features.
Most of the network features are driven from cluster level, we enable
using the features on all DC level (actually >=3.1) but actually enable
/disable the feature when attaching the network to a cluster.
So from network perspective I think it should be fine to downgrade the
DC level even if there are networks in the DC (at least now this could
change in future versions).
In general I believe the use case for this patch is mostly for empty DCs
so for simplicity we should block it if there are networks or SD in the
DC when downgrading.
