Hi @Sainath N, 

It doesn't seem ServiceNow has any public documentation available for this migration. Migrating from one system to another can be a complex process that requires careful planning. To ensure smooth migration, consider factors such as thorough planning, phased migration, risk mitigation plan, etc. You may refer to this blog for complete insight into the factors that must be considered. 

Once the pre-steps are finalized, selecting the right migration tool is the next crucial step. Considerations include no data loss, system downtime, and a highly secured and reliable approach.     

 OpsHub, a ServiceNow partner, has extensive expertise in undertaking complex migration projects, ensuring zero downtime, preserving data integrity, executing systematic cutovers, and employing a factory-style approach.  

Feel free to contact us for an initial free consultation on migration planning with our solutions architects.       

Thanks,

Vishal
