>                 Key: MINIFI-129
>                 URL: https://issues.apache.org/jira/browse/MINIFI-129
>             Project: Apache NiFi MiNiFi
>          Issue Type: Improvement
>          Components: Core Framework
>    Affects Versions: 0.1.0
>            Reporter: Andrew Grande
>
> Consider the following snippet below. My understanding, based on prior discussions, was that MiNiFi uses component and connection IDs only internally to wire everything together. My logic then was to rename the RPG connection ID and update relevant config sections.
> The problem is that MiNiFi properly instantiates the flow, but fails to find the RPG port: *failed to communicate with http://example.com/nifi because the remote instance indicates that the port no longer exists*. This is not true (port is there and the name is valid). However, as soon as I copy/pasted the incoming port ID from the cluster into minifi flow and updated it, things starting flow correctly.
> It will be a problem when minfii configs are moved from env to env or promoted within SDLC, as RPG ports will have different UUIDs every time.
> Proposal: have MiNiFi negotiate based on the port name only, and use connection id internally only.
