> If I try to change the version of a dataflow from Version 1 to Version 2, and
> the changes result in a connection being removed or its destination changing,
> all is OK If the destination is not an Output Port. However if the
> destination of the connection in the current version is an Output Port, and
> the Output Port is running, the connection will not be updated. The logs will
> show no errors, and the UI will either indicate that the connection couldn't
> be updated because the destination is running, or it will claim that the
> update was successful (depending on the situation). But in either case, the
> flow will not have been updated properly.
