3.2. Data Migration and Integration (Exam Domain 6: 15%)

💡 First Principle: Efficiently and accurately transferring data from external sources into ServiceNow ensures that the platform remains a comprehensive single system of record, without compromising data integrity or introducing duplicates.

Scenario: You need to integrate ServiceNow with an external HR system to import employee data. This requires understanding how data is structured in ServiceNow, how to map external data to it, and how to ensure only authorized personnel can access sensitive employee information.

This section focuses on the tools and techniques used to manage data behavior, migrate configurations, and extend platform functionality through scripting. You will learn about UI Policies for client-side logic, Business Rules for server-side automation, Update Sets for moving configurations, and the role of scripting in ServiceNow. These concepts are fundamental to ensuring data integrity and enabling controlled, scalable platform development.

⚠️ Common Pitfall: Not testing data migrations or integrations thoroughly in a non-production environment. This can lead to data corruption or unexpected behavior in production.

Key Trade-Offs:

• Automation vs. Manual Control: Automated integrations ensure continuous data synchronization but require careful setup and monitoring. Manual processes offer more control for one-off tasks.

Reflection Question: How do UI Policies, Business Rules, and Update Sets collectively contribute to maintaining data integrity and enabling controlled development and deployment in ServiceNow?
