Hi,
Would the use of VMWare vSphere fault tolerance be an option for ensuring your OCUM instance is highly available between sites in your environment? I'd assume you require a single instance of OCUM that is highly available between sites\datacenters without having to resort to backup\restore downtime? If so then in theory this might be an option for you depending on your vSphere\Network infrastructure and vSphere licensing as fault tolerance requires enterprise plus licensing.
