say cinder, where doing a list volumes would show up in both api's, so upgrading is smooth.<br>

<div>However, I'd like to raise same question on our Heat IRC meeting.</div>
<div>Probably we should define some common concepts, because I think, that lbaas is not single example of service with</div>
<div>several APIs.</div>

<div>As I understand it, loadbalancer in v2 is more like pool was in v1. Can we make it such that if you are using the loadbalancer resource and have the mandatory v2 properties that it tries to use v2 api, otherwise its a v1 resource? PoolMember should be
ok being the same. It just needs to call v1 or v2 depending on if the lb its pointing at is v1 or v2. Is monitor's api different between them? Can it be like pool member?<br>

<div>So for the API v1s api is of the structure:<br>
<br>
<neutron-endpoint>/lb/(vip|pool|member|health_monitor)<br>
<br>
V2s is:<br>
<neutron-endpoint>/lbaas/(loadbalancer|listener|pool|healthmonitor)<br>
<br>
member is a child of pool, so it would go down one level.<br>

The only difference is the lb for v1 and lbaas for v2. Not sure if that<br>
