How We Implement ECC → S/4HANA Migration

At Radiansys, our migration methodology is designed to minimize risk while maximizing long-term value. We combine SAP best practices with deep functional and technical expertise to deliver controlled, predictable migrations.

Readiness Assessment & Roadmap

We perform a detailed analysis of your existing SAP ECC landscape, including custom objects, interfaces, data volumes, and end-to-end business processes. This assessment highlights simplification opportunities, technical dependencies, potential risks, and functional impacts, resulting in a clear and actionable migration roadmap with defined phases, timelines, and effort estimates.

01

Migration Strategy Selection

Based on your business objectives, system complexity, and operational constraints, we recommend the most suitable migration approach, Greenfield, Brownfield, or Selective Data Transition. Each option is evaluated against factors such as risk exposure, downtime tolerance, data retention requirements, and long-term system maintainability.

02

Custom Code & Data Simplification

End-to-end testing and disciplined cutover planning to minimize business disruption and ensure a smooth go-live.

03

Clean Core Alignment

We assess existing custom code using SAP-recommended analysis and remediation tools to identify obsolete, redundant, or high-impact developments. Non-essential customizations are retired, while critical enhancements are redesigned in alignment with clean-core principles. Data models and structures are simplified to meet SAP S/4HANA standards and performance expectations.

04

Data Migration Execution

We execute structured data migration for master, transactional, and historical data through controlled and repeatable migration cycles. Data is cleansed, validated, and reconciled across systems to ensure financial accuracy, reporting consistency, and audit compliance prior to final cutover.

05

Go-Live & Post-Migration Stabilization

Following go-live, we provide focused hypercare support to stabilize operations, resolve issues, and optimize system performance. Our team monitors system usage, business processes, and reporting outcomes to ensure a smooth transition and sustained adoption of SAP S/4HANA capabilities.
