Hello, I am looking for assistance. Here are my Identification Rules, I am being told the Product Instance Identifier (which we are not using) should not be interfering with anything and it is fine being the OOB Rule and the highest priority. All my research is saying that it should be removed. Over the past few weeks I have had an increased in flip flopping serial numbers. An active CI that has been created manually through a MAC Flow is flip flopping with an already retired device in the CMDB. The only way I have found to resolve these flip flopping serial numbers is delete the both CI's and have them rediscover/recreate through SG-SCCM. I have been trying to track down the solution for this for 2 1/2 years and I just feel like I keep going in circles. Please note, we just upgraded to Yokohama in December and are priority used to be correlation ID first, which has sense been deprecated and correlation ID = serial number? Is that correct?

| 100 | Serial Number Table | serial_number, serial_number_type |
