HA250 – Database Migration Using DMO – SAP HANA 2.0 SPS07 — Lesson 4: Post-Migration Validation, Reconciliation, and Cutover Closure

Learning Objectives

• Explain how Post-Migration Validation, Reconciliation, and Cutover Closure supports controlled DMO migration.
• Complete the workflow and produce a reviewable DMO cutover assurance and closure plan.
• Evaluate the condition where the system starts successfully but a critical application total differs from the source and select a supported response.

Detailed Topics

• Technical consistency checks: monitoring views, reports, and indicators used to evaluate the completed process result.
• Application smoke testing: reconciliation tests that connect source data, documents, balances, and operational outcomes.
• Performance and data reconciliation: root-cause methods for separating data, configuration, access, timing, and execution issues.
• Operational handover and lessons learned: ownership, review frequency, escalation, and improvement controls required after handover.

Instructor Demonstration

Using the stated scenario, the instructor demonstrates Technical consistency checks, Application smoke testing, Performance and data reconciliation, Operational handover and lessons learned. Particular attention is given to object relationships, field or status behavior, integration effects, and how DMO cutover assurance and closure plan supports review. The demonstration deliberately introduces the exception where the system starts successfully but a critical application total differs from the source.

Hands-On Exercise

Complete a controlled activity covering Technical consistency checks, Application smoke testing, Performance and data reconciliation, Operational handover and lessons learned and preserve the final result in DMO cutover assurance and closure plan.

1. Define the expected business result and the SAP objects that should produce it.
2. Perform the lesson scenario, capturing before-and-after evidence for every material decision.
3. Test the exception without changing unrelated settings or data, then explain the first divergence.
4. Apply proportionate remediation and complete a focused regression test before handover.

Scenario Analysis

• Which SAP object, rule, master record, or process step most strongly influences the observed result?
• What evidence distinguishes a configuration problem from data, authorization, integration, or timing causes?
• How should the DMO cutover assurance and closure plan be approved, retained, monitored, and updated after handover?

Troubleshooting Guidance

Start at the earliest point where expected SAP behavior differs from the observed result. Review process sequence, master data, organizational assignments, configuration, authorization, integration, and timing separately. Treat “the system starts successfully but a critical application total differs from the source” as a testable hypothesis until settings, documents, logs, reports, and retest outcomes confirm the cause.

Validation Checklist

• Required structures, master data, roles, settings, and dependencies for Post-Migration Validation, Reconciliation, and Cutover Closure are present.
• The DMO cutover assurance and closure plan connects each conclusion to objective, reviewable SAP evidence.
• Normal processing, the stated exception, integration behavior, and access boundaries were tested.
• Corrections, retest criteria, ownership, documentation, monitoring, and operational handover are complete.

Lesson Outcome

Learners can apply Post-Migration Validation, Reconciliation, and Cutover Closure, explain the resulting SAP behavior, and defend the outcome through DMO cutover assurance and closure plan.
