Challenges You May Face When Migrating from ECC to SAP S/4HANA Cloud Private Edition and How VC ERP Consulting can Help?
Unclear Migration Strategy
VC ERP Consulting provides assessment workshops and uses tools like SAP Readiness Check and SAP Transformation Navigator to recommend the optimal migration strategy.
Complex Custom Code and Enhancements
ECC systems often contain decades’ worth of custom code that may not be compatible with S/4HANA. VC ERP Consulting conducts custom code analysis, identifies obsolete or incompatible code, and helps optimize or rewrites custom logic using tools like ABAP Test Cockpit (ATC) and SAP Fiori UX guidelines.
Data Quality and Data Migration
Poor data quality, redundant master data, and inconsistencies make migration risky and time-consuming. VC ERP Consulting performs data profiling, cleansing, and implementing data governance processes. We also use SAP Data Services and SAP Migration Cockpit for a smoother migration.
Integration with Legacy and Third-party Systems
S/4HANA PCE might require reengineering integrations with external apps, middleware, or legacy systems. With expertise in SAP BTP, Cloud Connector, and integration suites, we rebuild or refactor integrations to maintain business continuity.
Change Management and End-User Adoption
New processes, interfaces, and roles create steep learning curves for users. VC ERP Consulting offers training, enablement programs, and organizational change management (OCM) support to increase adoption, leveraging SAP Enable Now and Fiori Launchpad training.
Downtime and Business Continuity Risks
Businesses worry about system outages and operational disruptions during migration. By using Near-Zero Downtime and SUM-DMO tools, we design phased cutovers or parallel landscapes to minimize downtime.
Cloud Infrastructure and Operations
Managing private cloud infrastructure introduces new concepts, and that can be very overwhelming. VC ERP Consulting can handle technical architecture, infrastructure readiness, cloud provisioning, and ongoing managed services, often collaborating with your choice of Hyperscalers.

Frequently Asked Questions
What are the changes from SAP ECC to S4 HANA?
Thinking about migrating from ECC to SAP S/4HANA? It is essential to know about the changes from SAP ECC to SAP S/4HANA:
SAP ECC runs on multiple traditional databases and relies on a complex, table-heavy structure, with slower batch-based processing and a legacy GUI interface. In contrast, SAP S/4HANA is built for speed and simplicity, powered by the in-memory SAP HANA database, it offers real-time data access, a streamlined data model with the Universal Journal, and the modern, user-friendly SAP Fiori interface.
S/4HANA enables instant MRP, faster financial close, and efficient reporting, thanks to its simplified architecture and real-time capabilities. It also unifies customer and vendor data through the Business Partner model, mandates the Material Ledger for enhanced global inventory valuation, and revamps credit management with automated, intelligent FSCM tools.
In essence, S/4HANA offers a faster, cleaner, and more integrated ERP experience, positioning businesses for agility, insight, and growth.
What are the ECC to S/4HANA conversion steps?
Here are the ECC to S/4HANA migration steps from beginning to the end:
When is the end of support for SAP S/4HANA on-premise, and what are the implications for businesses still using it?
01 Assess & Plan
- Review current ECC landscape, business processes, customizations, and integrations
- Run SAP Readiness Check for simplification items, custom code, sizing, and compatibility
- Create a detailed migration plan using tools like Roadmap Viewer
02 Ensure System Readiness
- Confirm Unicode system; plan conversion if not
- Split dual-stack systems (ABAP + Java)
- Check minimum release level (see SAP Notes 3230844, 3145277)
- Remove obsolete Java components from LMDB
- Validate OS support for relevant Java instances (e.g., Adobe Document Services)
03 Reduce Data Volume
- Clean up obsolete/redundant data to shorten conversion time
- Use DVM Work Center for pre/post-conversion cleanup and size simulation
04 Run Compatibility & Software Checks
- Use Maintenance Planner to validate components, add-ons, and generate stack.xml
- Ensure SPAM/SAINT ≥ 71 and SAP Note 2186164 is applied
- Establish RFC connection to SAP Solution Manager
05 Perform Simplification Item Check
- Run report /SDF/RC_START_CHECK for system consistency
- Resolve red/yellow return codes before SUM process (Notes: 2399707, 2502552)
06 Analyze Custom Code
- Use Custom Code Migration tool to check compatibility
- Clean up unused custom code and adapt relevant CDS views
07 Validate Data Transition
- Use Data Transition Validation (DTV) to compare data pre- and post-conversion
08 Prepare Cross-Application Components
- Remove client 066
- Uninstall unsupported SAP Fiori apps
- Map roles to new authorizations and Fiori catalogs if adopting SAP Fiori UX
09 Prepare Application-Specific Tasks
