Unfortunately that is not an option. This was originally deployed by (a reputable VMWare Partner) and they were supposed to deliver a full HA (similar to I described but without the vIDM cluster).
However, the bean counters signed off before we could evaluate and review the delivered deployment/product and we discovered that they actually gave us a POC Minimal deployment.
I understand VRA and have done minimal deployments myself (without Load balancers, both in my personal lab and in another datacenter).
My quandary is the vIDM cluster.
You are correct that I am in over my head, but that is how the cookie crumbles... Learn and get it done. Hence why I am posting here.
