Amey, a UK-based infrastructure and engineering services company, has completed a large-scale ERP cloud migration. Under its modernization project, the company has moved from a 20-year-old SAP ECC system to SAP S/4HANA Cloud, Private Edition, hosted on Google Cloud Platform. According to a November 12 media statement from NTT DATA Business Solutions UK&I, the migration was delivered on time and on budget as part of Amey’s broader technology modernization program.
The implementation reportedly establishes a cloud-first foundation that supports Amey’s data, finance, procurement, and supply chain operations across its UK infrastructure services, which include transportation networks, utilities, and public services. The company’s goal is to better its operational agility and apply AI-enabled processes to areas such as resource planning and project execution.
Amey partnered with NTT DATA Business Solutions, which used a standardized conversion methodology through its SAP S/4HANA Technical Conversion Centre of Excellence. The approach emphasized automation, preconfigured solutions, and testing through Tricentis tools to validate core business processes and minimize disruption.
The project also delivered data quality improvements using Natuvion solutions, removing more than 100 redundant company codes to create a more efficient ERP environment and lower infrastructure costs. Additionally, Amey and NTT DATA Business Solutions conducted a pilot exploring the use of generative AI for highway safety to test how the platform’s potential can support future innovation.
Both organizations plan to continue collaboration through a long-term transformation roadmap that includes expanded SAP Fiori adoption, enhanced accounts receivable management, integration of SAP Business Data Cloud, and sustainability tools such as Green Ledger.
What This Means for ERP Insiders
Complex ERP transitions are becoming more predictable. Amey’s migration illustrates how established organizations with long-standing SAP ECC environments are completing full-scale transitions to SAP S/4HANA Cloud. It reflects a growing reliance on factory-style, automation-based conversion models to control cost and risk during complex cloud migrations.
Data readiness is emerging as a critical success factor. The project also highlights the importance of data readiness as a driver of post-migration efficiency. Streamlining company codes and removing obsolete data allowed Amey to achieve performance and cost improvements at go-live—a practice increasingly seen as essential to ERP modernization.
Automation and testing are redefining project assurance. For organizations planning similar programs, the use of automated conversion and advanced testing tools such as Tricentis may serve as reference points for balancing transformation speed with operational stability. Amey’s inclusion of a generative AI pilot further signals that companies are beginning to integrate advanced technologies into ERP initiatives early in their modernization cycles rather than as secondary projects.
