Beyond go-live: Why legacy system decommissioning is critical to long-term SAP S/4HANA success
Most SAP S/4HANA programs treat go-live as the finish line. In reality, it’s just the beginning - when the biggest risks and opportunities start to emerge.
After migration, many organisations keep legacy SAP systems running “just in case” - for audits, reporting, or regulatory needs. What feels like a safe fallback often leads to rising costs, increased cybersecurity exposure and unnecessary complexity. Just as importantly, fragmented and duplicated historical data undermines the ability to build a strong data foundation for analytics, AI and intelligent automation, eroding the long-term value of the S/4HANA investment.
In this webinar, we’ll explore why legacy system decommissioning is not just a technical clean-up, but a strategic decision that impacts cost, compliance and future insight. You’ll hear how leading organisations are responding to growing regulatory pressure, data volumes, and cloud transformation – and how simplifying the SAP landscape helps create a single, trusted data foundation for advanced analytics and AI-driven initiatives.
Through a real-world enterprise case study, we’ll show how decommissioning done right can reduce risk, lower total cost of ownership and create a cleaner, future-ready SAP landscape beyond go-live.
