Who it's for: Technical consultants, Basis administrators, and system specialists — and experienced SAP professionals moving into an S/4HANA transition role — who want a recognized specialist credential proving they can plan and carry out a technical SAP S/4HANA conversion and a full system upgrade end to end, from readiness analysis and tooling through data migration, custom-code adaptation, and post-change validation.

The SAP® E_S4CON certification confirms that a technical consultant can carry an existing SAP landscape onto SAP S/4HANA and manage a full release upgrade from an administrator's standpoint. Rather than testing terminology alone, it examines whether you can plan and run the transition end to end — assessing the source system, driving the maintenance and update tooling, migrating data, adapting custom developments that no longer fit the changed data model, monitoring the system through each phase, and validating the result afterward. Because it is delivered as a Scenario-Based Assessment built around a single realistic activity, the credential rewards applied technical execution over recall, and it also addresses cloud-oriented deployment considerations alongside the classic on-stack conversion path.
The blueprint areas to focus your preparation on.
Planning and running the technical conversion of an existing ERP system onto SAP S/4HANA — pre-checks and readiness analysis, the maintenance planner, the Software Update Manager phases, and the sequence that moves the source database and application stack onto the new platform.
Executing a release upgrade of an SAP system from the administrator's perspective — preparing the landscape, applying support packages and stack updates, and using the maintenance and update tooling to keep downtime controlled and the outcome consistent.
Handling the data-migration work a conversion requires — adapting to the simplified S/4HANA tables and structures, running the migration steps, and validating that business data lands correctly in the new data model.
Analyzing existing custom developments against S/4HANA requirements, identifying code that no longer fits the changed data model, and adapting or remediating it so custom programs continue to run after conversion.
Monitoring the system throughout the conversion or upgrade, tracking each phase for errors, and validating technical health afterward so issues surface before users are affected.
Weighing cloud-oriented migration and deployment options for the target S/4HANA landscape, including how infrastructure choices shape the conversion approach and ongoing operation.
