Hi @SandeepKSingh

ServiceNow’s Identification and Reconciliation Engine (IRE) uses identification rules to determine uniqueness. If the identification rule includes serial number as a unique key, the second discovery run will update the existing CI (same serial) instead of creating a duplicate. If the IP is part of the identification rule too, and both differ, IRE will create a new CI since it can’t confirm they’re the same asset.
