2 different versions of KIC deployed in one cluster for upgrade and rollback

Hi, we’d like to deploy two different versions of KIC connected to separate Postgres DBs on a single GKE cluster as part of the KIC/Kong upgrade process.

The one roadblock to implementing this is that typically CRDs need to be updated for every upgrade, and CRDs are cluster-scoped.

Is there a way for a version of KIC to use a specific version of CRDs, and have different versions of CRDs available?
