> We've been bitten a few times by downgrade incompatibilities. It should be straightforward to adapt our current upgrade system tests to support downgrades as well. The basic procedure should be: 
>  # Roll the cluster with the updated binary, keep IBP on old version
>  # Verify produce/consume
>  # Roll the cluster with the old binary, keep IBP the same.
>  # Verify produce/consume
