The session

About this session

Data migration remains one of the highest-risk elements of any S/4HANA transformation. Even with extensive planning, gaps in testing, reconciliation, source data and cutover readiness can remain hidden until go-live, resulting in duplicate postings, incomplete data loads, incorrect organisational assignments and disruption to business operations and financial reporting.

Drawing on real examples from an ECC-to-S/4HANA implementation, this candid case study examines how limited end-to-end testing, manual file preparation, missed source tables and compressed timelines contributed to migration issues. It also shares the practical recovery strategies, governance improvements and preventive controls that can reduce risk in future programs.

What You'll Learn

  • Identify migration risks that can remain hidden until go-live.
  • Strengthen testing, reconciliation and cutover controls.
  • Turn migration issues into practical improvements for future S/4HANA programs.
