Hi Chaitanya,

You may use Update Version (sys_update_version) table for your analysis. It persists any change to existing object (table, field, script..etc) and new objects too.

For any existing object, it would have more than one record if it was customized.

New records many have only one entry too. But you may find out the new ones by checking the creation date and any reference between parent object (for example new field added in incident table).

Hope this helps. Mark the answer as correct/helpful based on impact.

Thanks

Antin

it is very difficult , but you can achive in many ways identify variables and tables wise , how much customization you have done , if created by is not system vs created by is system will give you the percentage ...

We use to have Health scan report from servicenow, which use to tell what all we customized and how much % customization done.  This report tell you how far your instance deviate from OOB..

You can Raise HI ticket to get this report.
