Overview: Understanding SAP S/4HANA Conversion & Migration

What Is SAP S/4HANA Conversion & Migration?

SAP S/4HANA conversion and migration refers to the structured transformation of an organization’s existing SAP environment (typically ECC) into SAP’s next-generation ERP system—SAP S/4HANA.

It involves:

• Technical system transformation
• Business process redesign
• Data restructuring
• Custom code adaptation
• Integration realignment
• Change management and user enablement

Unlike traditional upgrades, S/4HANA migration impacts every layer of the enterprise, from database architecture to user experience.

Conversion vs Migration vs Implementation

To understand the landscape clearly, professionals must distinguish between three common approaches:

1. System Conversion (Brownfield)

• Existing ECC system converted to S/4HANA
• Retains historical data and configurations
• Faster but complex due to legacy constraints

2. System Landscape Transformation

• Selective carve-outs or consolidation
• Ideal for mergers, acquisitions, or multi-system landscapes
• Requires advanced data governance

3. New Implementation (Greenfield)

• Fresh S/4HANA system with redesigned processes
• Clean slate approach
• High business transformation value

SAP S/4HANA Conversion & Migration equips learners to evaluate and execute all three approaches professionally.
