Issue automating multiple tenants in vRO

Hi,

I'm struggling with the fact to manage multiple tenants with vRO and vRA.

Right now there are a couple of tenants hooked up to a single vRO appliance, but I'm looking to fully automatize everything (Fabric/Business groups, Reservations, Build Profiles, Blueprints, etc.)

In vRO we only have the default tenant configured (under vCAC Infrastructure Administration) because I cant seem to add more. From the default tenant I can't manage some of the above.

Is it best practice to deploy a seperate vRO instance for every tenant?

Running vRO version 6.0.1 and vRA version 6.2.1

Thanks in advance.
