SAP Upgrade & Migration
Move from SAP ECC to S/4HANA with confidence — choosing the greenfield, brownfield, or selective data transition approach that best fits your organization's needs.
Mainstream maintenance for SAP ECC ends in 2027, with extended maintenance available to 2030. Every organization running ECC needs a migration plan — and choosing the wrong approach can cost years and significant capital. Spirit's migration practice has delivered ECC-to-S/4HANA programs across multiple industries, using structured methodology to manage complexity and reduce risk.
Migration Approaches
- Greenfield — start fresh with a clean S/4HANA implementation; the required path for SAP S/4HANA Public Cloud, and the choice for organizations seeking full transformation
- Brownfield — system conversion retaining existing data, customizations, and processes (Private Cloud or on-premise)
- Selective Data Transition — a hybrid approach combining elements of both; ideal for complex legacy environments (Private Cloud or on-premise)
- Cloud migration — move to SAP S/4HANA Public or Private Cloud with managed infrastructure and bundled services
What Spirit Delivers
- Migration readiness assessment and approach recommendation
- Data cleansing, archiving, and selective migration planning
- Custom code remediation and simplification
- Parallel testing, cutover planning, and go-live support
Common Questions About SAP Upgrade & Migration
What's the difference between greenfield and brownfield migration?+
Greenfield migration is a new SAP S/4HANA implementation that starts from scratch, enabling organizations to redesign business processes, adopt SAP best practices, and build a modern, scalable ERP system. Brownfield migration is a SAP S/4HANA system conversion that upgrades an existing SAP ERP system while preserving current processes, configurations, customizations, and historical data. The right approach depends on your business goals. Organizations seeking full digital transformation and process optimization often choose Greenfield, while those looking for a faster, lower-risk migration with minimal business disruption typically choose Brownfield.
What's the deadline for moving off SAP ECC?+
SAP will end mainstream maintenance for SAP ECC 6.0 on December 31, 2027, with extended maintenance available until December 31, 2030 for eligible customers. Organizations still running SAP ECC should begin planning their migration to SAP S/4HANA to ensure continued support, access to the latest innovations, enhanced security, and long-term business continuity.
