Apigee Private Cloud Blue & Green Deployment

Hi Everyone

We are looking for a solution to have Apigee blue / green deployment on our Private cloud platform.

I know that this is implemented for public cloud, but I wanted to know if there is any plan for doing this in private cloud?

From what I can see in DevOps document there two choices either taking backup and restore on new release, which I believe will fail at the end of the day and doesn't worth it, or snapshotting the data volumes and restore them in our new release - which can be tricky with new apigee patches coming along in case they modify cassandra (version / schema) and zookeepr data structure.

If someone can shed some light on what apigee gurus doing at the moment for this type of problem, highly appreciate it.

Thanks.
