About Aunt Millie’s

OCI Global is a leading European producer and distributor of ammonia, nitrate fertilizers, and hydrogen products and solutions. With a 30-year history of building and scaling sector-leading businesses, OCI has returned $7 billion to shareholders since 2022.

The challenge:

Following several divestments, OCI needed a dependable way to retain and access historical business data for legal, tax, audit, and ongoing business needs. The organisation had previously worked across multiple SAP ECC systems before moving to S/4HANA on SAP Private Cloud in 2021 and later transitioned to S/4HANA Public Cloud. This left records split across both their former S/4HANA Private Cloud system and their remaining ECC systems, all of which needed to be kept securely and in line with compliance obligations.

A key part of this requirement was finding a solution that would lower cost by removing the need to maintain legacy systems and their ongoing licences. SAP Netherlands recommended Proceed Cella Cloud, which aligned well with OCI’s need for long term access to their data without maintaining old systems.

The solution: Proceed Cella Cloud

Proceed Group worked closely with OCI to shape a clear and structured approach to decommissioning and data retention using Proceed Cella Cloud.

Actions taken:

  • All legacy data from the S/4HANA production system and company code specific data from the ECC systems was extracted and migrated into Proceed Cella
  • Alongside the standard reporting available, additional custom reports were defined and created to support OCI’s teams across varied geographies and culture
  • A 5 year retention model was set up within Proceed Cella to support compliance

The impact

With their legacy data now hosted and managed in Proceed Cella Cloud, OCI has a stable and compliant solution in place. The organisation no longer needs to maintain legacy SAP systems, which has removed both cost and complexity. OCI confirmed that the savings achieved were significant, making the move to Proceed Cella Cloud a straightforward business choice.

Thank you to all those involved from both Proceed and OCI. The project was delivered with precision and supported by a highly professional, well led team focused on delivery excellence and strong project controls. The savings achieved by moving to Proceed Cella were significant, which made the decision to use Proceed Cella Cloud an easy one.

System decommissioning defined

System decommissioning focuses on retaining long-term access to the data that still matters once a legacy system has been switched off. It removes the ongoing cost and effort of keeping old applications running while ensuring important information remains secure, accessible and aligned with regulatory needs. It becomes especially relevant during mergers and acquisitions, business divestments, moves to new cloud applications, or an S/4HANA greenfield migration where only current data is taken forward. In these moments, older systems continue to hold records that must be kept, so having a structured plan for managing and storing that data is key. For a deeper look at how this works in practice, see our system decommissioning guide.
