Hi PG2,

If you are licensed for ITOM Service Mapping, one of the population methods for your Application Service should be used to maintain the dependency(stored as Service Configuration Item Associations) between the Application Service and the infrastructure CIs. 

If you used a pattern based population method (Mapped Application Service), when the original version of the Application Service is retired, the Load Balancer VIP used as your entry point for the Application Service should have been removed from the LB or the LB service should be modified to no longer reference the infrastructure CI. There is a daily scan of Load Balancer Services that will catch the update to the LB service.
