Risks of change to a physical configuration are minimized. A request for a change to the physical system included in the physical configuration is detected, and all applications the physical systems that would be affected by the requested change are identified. All the applications and physical systems that would be affected by the requested change are replicated on a virtual system, including applications and the physical system to which the requested change is targeted and applications and physical systems that are dependent on the applications and the physical system to which the requested change is targeted. The requested change is applied to the virtual system. The virtual system is tested to determine whether the applied change produces desired results. If the applied change products the desired results, the requested change is applied to the physical system.
