Six Compelling Reasons to Move Beyond SAP ECC
Choose Your S/4HANA Migration Path
Three proven migration approaches — SAVIC helps you select the right path based on your system landscape, business goals, timeline, budget, and risk appetite.
Brownfield — System Conversion
Convert your existing SAP ECC system to S/4HANA in-place — preserving historical data, configurations, and business processes while gaining S/4HANA innovations with minimal disruption.
- Retains full historical data and proven configurations
- Faster timeline (12–18 months) and lower initial cost
- Minimal business process disruption during transition
- Simplification item analysis and ABAP code remediation included
Greenfield — New Implementation
Implement SAP S/4HANA from the ground up — redesigning business processes using SAP best practices and industry templates for a clean, modern ERP foundation.
- Clean core architecture built on SAP best practices
- Maximum process optimization and modernization opportunity
- Future-ready platform with no legacy technical debt
- Full data migration from ECC to new S/4HANA system
Selective Data Transition (SDT)

Frequently Asked Questions
Everything you need to know about ECC to S/4HANA Migration with SAVIC Technologies.
What is the SAP ECC end-of-maintenance deadline?
SAP has confirmed that mainstream maintenance for SAP ECC (including SAP ERP 6.0 and Business Suite) ends on 31 December 2027. After this date, SAP will no longer provide standard support, legal change packages, or security patches for ECC systems under standard contracts. Extended maintenance options may be available at additional cost through 2030, but these carry premium pricing and do not provide access to new SAP innovations. SAVIC strongly recommends starting S/4HANA migration planning now — the average ECC to S/4HANA migration takes 12–24 months, making 2025 the last comfortable start point for most organizations.
What is the difference between Brownfield and Greenfield S/4HANA migration?
Brownfield migration (system conversion) upgrades your existing SAP ECC system to S/4HANA in-place — retaining all historical data, configurations, and customizations while gaining S/4HANA functionality. It offers faster timelines and lower disruption but carries existing technical debt. Greenfield migration deploys SAP S/4HANA as a completely new system — redesigning processes with SAP best practices, building a clean core, and migrating only required data from ECC. It provides maximum process optimization but requires more time and investment. Selective Data Transition (SDT) combines both — a new S/4HANA system with selective data migration from ECC. SAVIC helps organizations choose based on their timeline, budget, technical debt level, and transformation ambitions.
What happens to our custom ABAP code during ECC to S/4HANA migration?
Custom ABAP code must be analysed and remediated for S/4HANA compatibility before migration. SAVIC runs SAP's ABAP Test Cockpit (ATC) and Custom Code Migration app to identify all compatibility issues — including use of deprecated tables, APIs, and functions, compatibility scope violations, and clean core framework gaps. Our ABAP development team remediates all identified issues as part of the migration scope. In some cases, custom code can be eliminated entirely where SAP standard S/4HANA functionality now covers the requirement.
How long does an ECC to S/4HANA migration take?
Migration timelines vary by scope and approach. Brownfield conversions for mid-size ECC landscapes typically take 12–18 months from project start to go-live. Greenfield implementations generally take 18–24 months. Selective Data Transition projects run 15–24 months. Key variables include: system complexity and number of modules in scope, custom code volume, data migration complexity, number of integrations, and organizational change readiness. SAVIC provides an accurate timeline estimate following an initial readiness assessment.
What is SAP Readiness Check and should we run it before starting?
SAP Readiness Check is a free SAP tool that analyses your ECC system and generates a detailed report covering: custom code impact on S/4HANA compatibility, simplification item checklist, add-on compatibility assessment, and recommended migration approach. SAVIC runs SAP Readiness Check as the first step of every ECC to S/4HANA migration engagement — it typically takes 1–2 weeks and provides an essential baseline for migration scoping, effort estimation, and approach selection.
