Phase 22 — Migration & Modernization

Migration is not a copy exercise. It is the controlled redesign of data, semantics, integrations, security, operations, and consumption while protecting business continuity.

This phase teaches a repeatable modernization method for SAP Datasphere landscapes: assess the current estate, select a target pattern, migrate in waves, reconcile data and semantics, cut over safely, and retire obsolete components only when evidence supports it.

What you will learn​

  • How to distinguish lift, shift, re-platform, refactor, and retire decisions.
  • How to assess BW, BW/4HANA, S/4HANA, HANA, cloud warehouse, and non-SAP estates.
  • How SAP BW bridge and SAP Business Data Cloud fit into different modernization paths.
  • How to design coexistence instead of forcing a risky big-bang migration.
  • How to build reconciliation, cutover, rollback, and decommissioning controls.
  • How architects balance business value, technical debt, risk, performance, security, and cost.

Phase outcome​

By the end, you should be able to produce a migration strategy and defend the target architecture, migration waves, controls, risks, and retirement criteria for an enterprise Datasphere program.
