Use an Active/Passive Strategy

When designing an HA configuration, the biggest problem is downtime. You can minimize downtime by having a warm standby/passive server ready for action. If a disaster or a failover event occurs, a warm standby/passive server minimizes the downtime.
You can clone the Enforce Server (with all services stopped and disabled) for use in the warm standby/passive instance. Keep the services stopped and disabled until the server activates.
