Hyper-v-server reclassified in to windows server after running integration hub ETL.

[SNOW44]

Hello Everyone, 

There was a CI called X in Hyper-V-Server with serial number 123, And another CI in windows server class having CI name X with different serial number 456.

 Now we trying to import data using Integration hub for windows class having X with serial number 456 & it is updated and another CI in same sheet with name X with different serial number 789. When it is imported, it is updated the CI(Hyper-v-server) in to windows class and changed it serial number from 123 to 789.

CI in hyper-v-server is reclassified into windows server.

Is this an issue or good behavior of tool?

Thanks in advance

That seems like an issue to me, and I'm wondering if perhaps you have modified your Hardware identifier priorities so that Name is taking precedence over Serial Number.  If so, then you should revert this back to OOB configuration, as serial number is always a more trustworthy identifier than name.

I see my hardware rule are not modified, is there any other I'm missing out?

Nothing is coming to mind.  There is no way that a Service Graph Connector should be doing this because it should be using IRE, which means that it should be identifying the Server.  Are you sure you are seeing this properly and not getting confused?  Are you sure that for a given CI of a specific sys_id value, you are seeing the Class and serial number get switched?  This could only mean that class switching is being allowed and that name is being treated as higher priority than serial number, which should not be possible for a proper service graph connector...

Are you sure that for a given CI of a specific sys_id value, you are seeing the Class and serial number get switched - 

Yes, both class and serial number is changes. In IRE logs I found one interesting thing like it is matched with serial number. To be real, it is matching with name not with serial number.

Below is the IRE logs,

Serial number what is present initial is changing into serial number given in sheet where both are different. And IRE says it is matching with serial number. But what I observe is name is matching in two class(Windows server & Hyper-V-Server).
