This is not necessarily a deal-breaker, but just something to call out.
We don't have backwards compatibility with this change. It would be nice
to maintain backwards compatibility in this case because we don't quite yet
have feature parity. We are missing pcap search and comparable out-of-the-box
histograms in Kibana 4.
It would be achievable by renaming the existing roles to
`elasticsearch1`/`kibana3` and add the new functionality as
`elasticsearch2`/`kibana4`. I haven't looked yet, but we might have to
untangle some of the platform code too. The effort on the platform side may
not be worth it.
