How to get user table records in customer_contact table

[Shruti Chennuri]

I have a requirement to get sys_user table records to customer_contact table. All the records from user table should be present in customer_contact table as well. Please help me understand how this can be achieved. 

Thank you

This is a strange requirement. Could you validate the use case of why this requirement has been placed? sys_user table contains both requestors and fulfillers, so I would suggest to talk to your ServiceNow admin and solution architect to validate this requirement and ensure that there is no licensing infringement by doing this.

customer_contact and sys_user are two different tables. customer_contact is extend from the sys_user table and should only contain external users. So all your customer_contact records will be available in the sys_user table. Although, vice-versa is not the case. This is to distinguish between internal and external users. It is a bad practice to give a user both internal and external roles. If an internal user is also a contact, then in that case there should be a separate customer_contact record for that user.

That being said and advising to proceed with caution:

These are two different tables and you can write a script to copy over the records from one table to the other. All user records have the sys class name sys_user and all the contacts have the sys class name customer_contact. If you have a lot of records then I would recommend to execute them in batches and in the after work hours to ensure that the instance is not slowed down due to processing.
