The company is a leading manufacturer with more than 160 years in business and $1.3 billion in 2023 revenue. It has 19 manufacturing facilities, over 3,500 employees, and has made 11 acquisitions since 2016.

Two years after successfully implementing SAP S/4HANA, the manufacturer recognised the need to decommission its legacy SAP ERP system, aiming to streamline its complex SAP landscape. A key challenge was the need to preserve critical legacy data, including data from divested companies still under audit and HR data for retired pensioners, for long-term access. What’s more concerning is that the company is supposed to pay extra software maintenance and licensing fees if it fails to demonstrate that the systems were fully decommissioned.

To overcome this challenge, TJC Group developed a comprehensive approach based on a system decommissioning strategy centred around ELSA, a cloud-based legacy data archiving solution developed by TJC Group.

Our experts employed a perfect strategy of using the Audit Extraction Cockpit (AEC) software solution to extract all the data from the SAP ECC system. The extracted data was securely stored in Cloud BLOB storage, and the data needed for day-to-day retrieval was loaded into ELSA. ELSA allows users to access and retrieve data through SAP-like views, without the need to maintain a full SAP landscape. This project was implemented in four phases, where the team delivered a proof of concept (POC). Once the POC was approved, a pilot phase with a full dataset was initiated, followed by a full product implementation.

When the decommissioning project was completed, and the SAP ECC was shut down, end users could see all historical data within ELSA. The customer achieved significant cost savings from legacy system decommissioning with the help of TJC Group.
