Hello friends,

 

I come across one question in one of the meeting.

 

If there are large amount of duplicates in CI class (>25000). What will be my approach to remove / remediate these duplicates ?

 

Please suggest a best approach for this.

 

Thanks,

Asmi

Hi @Asmita7  please use the de - duplication task method   navigate to Configuration > Identification/Reconciliation > De-duplication Tasks.

 

Please accept my solution if it is helpful.

Hi @sanketmohit 

Thank you.

Will de-dup task approach good for 25000 CI's?

hi @Asmita7 
You have two options for deleting CIs from the CMDB:
1. Direct Deletion:
Confirm the CIs to be deleted and create a backup of these records.
Proceed with deletion using a background script or the de-duplication task remediator.
2. Archival Before Deletion:
Archive the CIs using CI Archive Rules, retaining them in the archive tables for 30 days or longer.
Delete the CIs from the archive once the retention period has passed.
