Hi All,

For on-premises (self-hosted) ServiceNow environments, the standard "System Clone" automation found in cloud-hosted instances is typically unavailable because these instances lack direct connectivity to ServiceNow's automated data center tools. 

Instead, you must rely on manual database-level operations managed by your internal database team. Here is a refined version of your guidance: 

  • Database Team Involvement: Since there is no automated "direct way" to trigger a clone from within the platform, you must coordinate with your database administrators to manually replicate the database from the source to the target instance.

  • Table Exclusion Best Practices: It is essential to identify and provide your database team with a list of tables to exclude or preserve before the migration starts. This prevents environment-specific settings (like dev-only configurations) from being overwritten.

  • Common Tables to Exclude:
    • User & Security: sys_user, sys_user_group, and sys_user_role.
    • System Configuration: sys_properties and sys_choice.
    • Logs: Audit, event, and system logs.

  • Estimated Duration: In a typical on-premises environment, the process of backing up, transferring, and restoring the database generally takes approximately 5 to 6 hours, depending on database size and network speeds.

Hi @glideFather ,

The Question was posted by me and the solution that worked out for me that I mentioned above.
I implemented it in my project recently that's why I mentioned the process above.

Because if you check the other solutions it's mentioned that It was not possible OOB. But the solution that worked out for me I mentioned that only ..

and Community give me the option to accept the solution that I mentioned above. So did so .

Regards,

Sagnic
