Migrating to SAP S/4HANA offers significant opportunities for businesses to streamline processes, gain real-time insights, and drive innovation. However, choosing the optimal migration path requires careful consideration of various factors. This article explores critical decision-making points and offers guidance for a successful SAP S/4HANA transition.
New Implementation vs. System Conversion
The most fundamental decision is whether to opt for a new SAP S/4HANA implementation or convert your existing SAP ERP system. Key factors influencing this choice include:
Initial Situation: If your current system is not SAP ERP 6.0 or higher, a new implementation is necessary.
Custom Code: Extensive custom code in your existing system may make a new implementation more practical if you're open to rethinking your business processes.
Data Quality: For complex or poor-quality data, a new implementation with selective data transfer might offer advantages.
Planning Tools for Guidance
SAP offers several tools to assist with individual planning and help you make informed migration decisions:

Defining Your Target Landscape
Alongside migration approaches, defining your future system landscape is crucial. Consider;
Consolidation: If you have a decentralized system landscape, migrating to SAP S/4HANA presents an opportunity to consolidate systems, streamline processes, and reduce operational costs.
Global Views: Centralize systems that require global visibility (e.g., SAP BW or SAP BPC) to gain real-time insights across your organization.
Mission-Critical Systems: Retain essential systems like SAP EWM as single systems, but consider co-deployment where processes can be tightly integrated with SAP S/4HANA for greater efficiency.
Scenario Selection and Sequencing
Once your target landscape is defined, determine the most suitable migration scenario and the appropriate sequence of steps. Think about;
System Conversion: May be suitable if your current system provides a good basis for your target landscape.
New Implementation: Consider if significant changes to processes or extensive custom code exist.
Sequencing: Carefully plan migration steps, particularly if you're consolidating multiple SAP ERP systems.
Additional Considerations
Thorough Evaluation: Assess all relevant factors from technical checks, custom code, business processes, and more to make a well-informed decision.
SAP Services: If needed, utilize SAP's various services for a customized recommendation.
Your Roadmap: While this article provides examples, your company's specific situation will likely require a unique roadmap for a smooth SAP S/4HANA migration.
In Conclusion
Migrating to SAP S/4HANA requires thoughtful planning and careful assessment of your company-specific needs. By leveraging the tools and considerations provided, you can confidently determine the most effective path and ensure a successful transition to this powerful next-generation business suite.
