Can anyone please explain in detail how to Configure automatic CI reclassification in input payloads?

Aditi Sharan · ‎08-11-2022

I'm completely new to this and having a hard time to understand all the things written here https://docs.servicenow.com/bundle/quebec-servicenow-platform/page/product/configuration-management/concept/c_CIReclassification.html#c_CIReclassification

So can anyone please guide me in a step by step manner. I'd really like to understand how this works practically!

Thanks

Hi,

in input payloads, you can just enable or disable specific types of reclassification for each payload independently, or provide additional rules restricting when this behaviour can occur.

Normally they are controlled by 3 global system properties, as mentioned in that article.

How this works, is let's say for some reason a server was initially classified as Server "cmdb_ci_server". When running another update of this CI (e.g. after the Identification Rules have been changed), reclassification automatically changes the CI class to Windows Server "cmdb_ci_win_server". This would be an example of an Upgrade (moving from less specific to more specific CI class).

A Downgrade would be the opposite (moving down in the CMDB hierarchy from more specific to more generic).

a Switch is moving to a sibling Class - e.g. from Linux Server to Windows Server.

If you disable any of those properties globally or temporarily, Reclassification tasks will be created which you can review and manually handle.

Thanks a lot Tomasz,

So how do we define these re-classification types in the input payload? How will the system know that we want to upgrade/downgrade a CI class in the first place?

Is there any article or video that i can follow to learn about the process from start? Please let me know if you are aware!
