The result establishes what requires action, what belongs in migration scope, and what should be removed before it reaches the SAP S/4HANA core.
Determine Your Path to SAP S/4HANA
SAP supports different transition approaches depending on the existing landscape, data requirements, process design, organizational change, and modernization goals. Current SAP guidance includes System Conversion, Selective Data Transition, and New Implementation for SAP ERP transition scenarios.
System Conversion
Convert the existing SAP ECC environment to SAP S/4HANA while retaining relevant configuration, processes, custom developments, and historical data.
Consider when
- Existing processes remain relevant
- Historical data needs to stay in-system
- Organizational structures remain stable
- Major process redesign is limited
Selective Data Transition
Move selected configuration, organizational structures, master data, transactional data, and history into the target SAP S/4HANA landscape.
Consider when
- Systems require consolidation
- Selected history needs to move
- Organizational structures are changing
- A phased transition is required
New Implementation
Establish a new SAP S/4HANA environment using standardized processes and migrate the business data required for future operations.
Consider when
- Legacy complexity is extensive
- Processes require major redesign
- Customization has accumulated
- A cleaner ERP foundation is required
Address Conversion Risk Early
Business Partner and CVI
Validate customer and supplier synchronization, mappings, number ranges, relationships, duplicates, and conversion readiness.
Finance
Assess Universal Journal implications, ledgers, currencies, Asset Accounting, controlling, reconciliation, period close, and inventory valuation requirements.
Custom Code
Identify which developments remain business-relevant and where standard SAP capabilities or modern extensibility can replace legacy customizations.
Data
Determine what needs to migrate, what can be archived, where quality issues exist, and how data volumes affect conversion and cutover.
Integrations
Map SAP and non-SAP dependencies, then identify interfaces that can remain, require remediation, or should move to current integration patterns.
Clean Core
Evaluate the target landscape across SAP's clean core dimensions, including
- Business processes
- Extensibility
- Data
- Integration
- Operations
Modernize Without Carrying ECC Complexity Forward
Fit-to-standard processes
Reduced core modifications
Released SAP APIs
Governed extensibility
SAP BTP where appropriate
Controlled data growth
Standard integration patterns
Clean core governance
Our SAP S/4HANA Modernization Approach
Discover
Assess the ECC landscape, business priorities, migration options, and modernization scope.
Prepare
Confirm the roadmap, governance, prerequisites, technical environment, and project readiness.
Explore
Run fit-to-standard workshops, validate requirements, and define the target SAP S/4HANA design.
Realize
Configure, remediate, migrate, integrate, test, and validate the SAP S/4HANA environment.
Deploy
Complete production cutover, reconciliation, business readiness, and go-live.
Run
Stabilize operations, monitor performance, manage clean core practices, and support continuous improvement.
Build an SAP S/4HANA Core Ready for What Comes Next
SAP S/4HANA modernization should establish a foundation that can continue evolving after migration.
SAP’s current technical documentation continues to use SAP S/4HANA as the umbrella term in contexts that can apply to both SAP S/4HANA and SAP S/4HANA Cloud Private Edition, unless a distinction is specifically required.
