I assumed they couldn't run on the same host, but would work on different hosts. maybe I was wrong?
I've got a production cloud that's heavily using v1. Having a flag day where we upgrade all from v1 to v2 might be possible, but will be quite painful. If they can be made to co'exist, that would be substantially better.

Versioning an advanced service is a whole other topic and exposed many "interesting" issues with the neutron extension and service plugin framework. The reason v1 and v2 cannot be run together are mainly to get over an issue we had with the 2 different agents which woudl have caused a much larger refactor. The v1 OR v2 requirement was basically a hack to get around that. Now that Octavia is the reference implementation and the default, relaxing this restriction shouldn't cause any problems really. Although, I don't want to 100% guarantee that because it's been a while since I was in that world. If that were relaxed, the v2 agent and v1 agent could still be run at the same time which is something to think about. Come to think about it, we might want to revisit whether the v2 and v1 agent running together is something that can be easily fixed because many things have improved since then AND my knowledge has obviously improved a lot since that time. Glad yall brought this up.
