The Ultimate SAP S/4HANA Migration Playbook: Choosing the Right Path (Brownfield vs. Greenfield vs. Selective Data Transition)

Moving from SAP ECC to S/4HANA is the most important technological decision your organization will make, but choosing the correct migration path is complex. The wrong choice, Brownfield, Greenfield, or Selective Data Transition (SDT), can lead to costly delays, unnecessary data clutter, and major business disruption.

This transformation requires an expert-guided strategy to maintain data integrity and business continuity during structural change.

ERPfixers, founded by an SAP expert who noticed a significant disparity in SAP knowledge accessibility, is dedicated to empowering clients with reliable, accurate SAP solutions. We bridge the gap by providing independent, practical advice that bridges the gap between IT and Finance.

We designed this Playbook to give business leaders the framework needed to confidently select the optimal path and execute a flawless transition.

Inside Your Strategic Migration Playbook, You Will Master:

This expert guide equips you with the framework to navigate the three paths and evaluate the critical factors defining your success:

  • Path Definitions: Understand the precise Definition and Scope for Brownfield (System Conversion, retaining data), Greenfield (New Implementation, a fresh start), and Selective Data Transition (a hybrid approach utilizing Central Finance principles).

  • Risk vs. Reward: Evaluate the strategic pros and cons of each path, including the risk of carrying forward historical complexity and custom code (Brownfield) versus the high organizational change management effort required for Greenfield.

  • Critical Evaluation: Utilize our framework to map your needs to a path by assessing Data Quality, Custom Code volume, and Process Efficiency (leveraging findings from an SAP Optimization Assessment).

  • FI/CO as the Epicenter: Recognize that the S/4HANA transformation is fundamentally a financial evolution. We analyze the impact of the Universal Journal (ACDOCA) and the mandatory Material Ledger (ML) on your chosen path, an area where ERPfixers provides primary expertise.
