SAP ECC to S/4HANA Migration

Find the Right Path from ECC to S/4HANA

There is no single approach that fits every SAP environment. Your business priorities, technical debt, custom code, data, integrations, end state (On-prem, RISE, or GROW) and appetite for process change all shape the decision.

• Brownfield conversion: Convert an existing SAP ECC system to S/4HANA while retaining much of its established configuration and processes.
• Brownfield+: Build on a system conversion with a more deliberate effort around a specific content area, rationalize custom code, reduce data volumes, simplify processes, and move toward a clean core.
• Bluefield / Selective Data Transition (SDT): Selectively move and transform relevant data and structures into a reshaped S/4HANA landscape.
• Greenfield implementation: Establish a new S/4HANA environment around redesigned or standardized processes.

Make the Decision Before Design Begins

SAP S/4HANA Decision Blueprint. A focused Phase 0 assessment that brings landscape facts and business priorities into one executive-ready roadmap. It helps leadership decide what to fund and gives the delivery team a clearer starting point for design.

The Blueprint examines your SAP business objects, organizational structures, customizations, integrations, data, and technical debt. Using AI-assisted analysis alongside System Compare, Customization Scan, and a Project Stress Curve, we evaluate fit and gap, remediation needs, simplification opportunities, effort ranges, risks, and sequencing.

The output is a recommended path with value hypotheses and design-ready work packages. Depending on complexity and the decisions required, engagements can begin with 2–4 weeks of Rapid Readiness or a 6–8 week Detailed Roadmap.

From Blueprint to Execution

Once the path is set, Consulting Solutions can support the full program or the workstreams where you need us most. Our teams help turn the roadmap into delivery plans for custom-code remediation, integration, security, data, testing, cutover, and adoption.

That may mean leading a brownfield conversion, supporting a brownfield+ simplification effort, delivering a selective data transition, or providing specialists for a defined challenge. We apply appropriate AI-enabled tools to help analyze migration backlogs, identify remediation priorities, prepare regression testing, plan cutover, and reconcile data—with practitioners accountable for the decisions and results.

Engage us through strategic advisory, project-based delivery, managed services, or specialized SAP talent.

A Greenfield Path with GROW with SAP

For organizations ready to establish a new ERP foundation, GROW with SAP S/4HANA Cloud Public Edition offers a fit-to-standard, SaaS-based path. It can suit growing businesses, subsidiaries, and divisions that want modern processes without carrying forward an extensive legacy configuration.

In one two-tier ERP engagement, we helped a B2B services business replace Microsoft Dynamics AX with S/4HANA Public Cloud while maintaining alignment with its parent company’s SAP ECC core. The program included SAP BTP Integration Suite, Vertex tax integration, SailPoint identity governance, reporting, and post-go-live support.

Put Data at the Center of the Plan

Data is often one of the most complex parts of an S/4HANA program. Selective Data Transition (SDT) gives organizations a way to choose which data moves forward and, where needed, restructure or transform it. SAP Business Transformation Center supports a Lean Selective Data Transition approach for future-relevant business data.

Consulting Solutions helps determine whether Lean SDT or a more extensive Robust SDT approach fits your objectives:

• Lean Selective Data Transition: Focus on a defined scope of relevant data and simplification.
• Robust Selective Data Transition: Address more complex data, historical, organizational, or landscape transformation requirements.

Our SAP Data Transformation Analysis provides a deeper view of business objects, customizations, dependencies, and data quality so teams can decide what to retain, migrate, harmonize, consolidate, or transform. These capabilities also support mergers, acquisitions, divestitures, carve-outs, system consolidations, and organizational restructuring.
