Removing data from OOTB classes

[Asmita7]

Hi friends,

1. I need to reclassify the records from Desktop (CI class) to it's parent Computer class without loosing it's asset side data and attributes?

Please help.

Thank you in advance.

Hi @Asmita7 ,

It sounds like the custom Desktop model category is still driving the synchronization between alm_hardware and your custom CI class. That's likely why the Hardware Model keeps reverting back to Desktop whenever a related record is updated.

For point #1, I'd recommend checking the Model Category mappings and any custom Business Rules, Flows, Script Includes, or Fix Scripts that reference the custom Desktop class/model category. In many implementations, the model category is automatically recalculated based on the CI class, so unless that mapping/custom logic is removed, the value may continue to revert.

For point #2, since your custom Desktop class is a child of cmdb_ci_computer, the safest approach is to use the CI Reclassification process to move records from the custom class to cmdb_ci_computer rather than directly updating sys_class_name. Reclassification typically preserves the CI record, relationships, asset association, and inherited attributes while changing the class.

My suggested approach would be:

• Stop creating new records in the custom Desktop class.
• Identify and remove the logic that is forcing the Desktop model category.
• Test reclassification on a small set of CIs from the custom Desktop class to cmdb_ci_computer.
• Validate that the linked Asset records, relationships, and discovery updates remain intact.
• Perform the bulk reclassification.
• Update the Hardware Models to use the OOB Computer model category and retire the custom Desktop model category once everything is validated.

Also, make sure to take a backup/export of the impacted CI, Asset, and relationship tables before performing the bulk migration.
