System decommissioning often sounds like shutting down and discarding – but your historical SAP data doesn’t have to be lost. With the right strategy, you can continue to access old data even after migrating to S/4HANA, without having to keep your legacy system running.
Why SAP System Decommissioning Matters
After an S/4HANA migration, the question arises: What happens to the data from the old ERP system?
Legacy systems not only generate license and operating costs but also tie up valuable IT resources. At the same time, legal requirements such as compliance, audits, or documentation obligations make access to historical data absolutely necessary.
The Challenge in Detail
A frozen legacy system can make data access difficult or even impossible. Essential data relationships between tables and business processes must be preserved so that analyses and audits remain feasible. Many solutions for system decommissioning are complex, non-transparent, or require extensive implementation effort.
The Solution: Smart System Decommissioning
itesys relies on the proven product Nearline Analytic Archive (NAA) from PBS Software GmbH for system decommissioning—a smart solution that enables historical SAP data to be efficiently transferred to an archive system that remains accessible via your S/4HANA system. The implementation is straightforward, and operation is GoBD-compliant and data protection–compliant (e.g., GDPR).
For companies that prefer a centralized and automated SAP data archiving approach, the Savento Tower Archive Manager is also available. This allows you to maintain a clear overview of archive jobs, storage locations, and data flows at all times.
