Retail 360 Legacy Modernisation and Migration

A major differentiator for retailers is the ability to orchestrate high-quality, personalised, omnichannel customer experiences. This requires accurate, timely, connected data supported by a modern, composable technology stack—none of this is possible with a siloed, legacy technology and data estate.

Addressing legacy technology represents retail's most significant transformation opportunity since the Internet. This is especially true for large, multichannel heritage brands.

However, too often, retail transformations to modernise and migrate legacy technology have treated technology, data, and customer experience (CX) as separate entities. This has reduced speed to value and limited effectiveness, ultimately leading to failure.

At Zühlke, we believe that breaking silos unlocks value, accelerates progress, and enhances innovation. That is why we developed our** 360 Modernisation and Migration for Retail** offering: to deliver a vertically sliced Proof of Value for a modern, cloud-based application. By uniting the proven methods of AWS Data-Driven Customer Experience (DDCX) and the Migration Acceleration Program (MAP), we multiply and accelerate the value of retail transformation.

• Go broader - address legacy holistically impacting touchpoints for internal and external customers and users, incorporating people, process, and technology elements to deliver rapid, incremental value aligned with business objectives and technology capabilities.
• Go deeper - unify data across systems, including OMS, WMS, ERP, CDP, and more, to reduce friction in customer journeys, surface deeper real-time insights, support predictive analytics, and unlock value from automation.
• Go faster – prioritise based on customer experience and ensure a seamless transition from prototype to Proof of Value. This will ensure initial concepts can be quickly validated and scaled to deliver tangible business value.
• Go further – establish a flywheel of opportunities where initial data insights into customers, stock & inventory, and supply chain create momentum, leading to continuous improvement and value creation, establishing a scalable technology foundation for ongoing innovation.

• Production-ready Proof of Value for an initial use case
• First vertical slice to establish a flywheel of opportunities and inform your migration strategy
• Feature roadmap for continuous innovation
• An architecture vision with a practical roadmap, including recommended AWS tools and services necessary for legacy modernisation and migration. This might include services such as AWS Database Migration Service, AWS Data Sync, Amazon RDS/Aurora, Amazon ECS, AWS Lambda, and the AWS Well-Architected Framework, with practical insights on how each will enable your business objectives.
