Data Migration of Domain Seperated Data from one instance to another instance.

There are questions on Data migrating (specific data - Domain Separated) from one instance to another instance.

1. Is there any process or tool which can move the Domain Separated data

- Please review the below documentation on Domain Migration Tool

https://docs.servicenow.com/bundle/rome-platform-administration/page/administer/company-and-domain-separation/concept/tenant-domain-migration-tool.html

2. Can we move the complete data of one instance to another instance without changing the data on the target instance?

- This can be achieved by Clone, Where clone will copy the data of Source instance and at the same time preserves the target instance data when added in preservers.
- Support will not have scope for the identification of the tables as they cannot determine how many tables are affected as a whole.
