What happens if I don’t migrate from SAP ECC by 2027? What support options exist after the end of mainstream maintenance?
After 2027, mainstream maintenance for SAP ECC will end for most customers. Organisations can choose extended maintenance from SAP until 2030 for an additional cost, transition to third-party support providers, or continue using ECC without comprehensive support. Delaying migration increases security, compliance, integration, and operational risks, and limits access to new AI and cloud innovations. 
What is the SAP ECC to S/4HANA migration cost UK 2026?
The cost of migrating from SAP ECC to S/4HANA in the UK depends on business size, customisations, data complexity, deployment model, and migration strategy. Typical expenses include licensing, infrastructure or cloud services, implementation, testing, data migration, integrations, training, and ongoing support. An in-depth SAP assessment is required to provide an accurate estimate.

Explain the technical differences between SAP ECC 6.0 and SAP S/4HANA in simple terms
 SAP ECC 6.0 is a traditional ERP system based on older database architectures. In contrast, SAP S/4HANA is a modern ERP platform designed to run on the high-speed SAP HANA in-memory database. In simple terms:
  • ECC stores and processes data using traditional methods, often relying on batch processing and separate reporting systems.
  • S/4HANA enables real-time processing, faster analytics, simplified data structures, and embedded AI capabilities.
  • S/4HANA also provides a modern user experience through SAP Fiori apps and improved integration with cloud technologies and automation tools.
