Learn How to ConfigMgr SCCM Merge Obsolete Duplicate Records

Let’s learn how to ConfigMgr SCCM Merge Obsolete Duplicate Records. I have a post with a detailed solution to remove duplicate record issues in SCCM.

Records with the same name but different GUIDs and hardware IDs are called Duplicate or Conflict Records. This happens when a machine already has a record in SCCM, is modified, and generates a new GUID.

However, we can use the following method to resolve duplicate records for the latest version of the Configuration Manager (a.k.a ConfigMgr) CB.
