While your organisation races forward with cutting-edge SAP solutions, legal requirements, business continuity, and operational needs still demand access to historical data. Yet maintaining legacy systems post-migration creates a critical financial drain and security vulnerability that a few transformation plans adequately address.

The true cost of keeping legacy systems alive:

    • Mounting licensing fees for diminishing returns

    • Infrastructure expenses that drain innovation budgets

    • Security vulnerabilities that grow more dangerous by the day

    • Compliance risks that increase with every passing month

    • Technical debt that undermines your transformation investment

    • The blind spot in transformation planning: Why 83% of organisations underestimate legacy data access requirements until it’s too late

    • ELSA revealed: How our modern historical data hub eliminates legacy system costs while preserving critical information access

    • Real-world success stories: Essential ELSA use cases during and after S/4HANA transformations

    • Beyond ERP: How ELSA solves complex data challenges in M&A transactions, divestitures, and HCM transformations
