Key Takeaways
- 51 Overnight conversions and 27 warehouse migrations in one year
Large-scale modernisation can be delivered through disciplined, repeatable execution, even across a highly diverse warehouse network.
- Stability through massive business and technology change
Successful transformation depends as much on operational resilience and people-led change as it does on technology.
- A platform for what comes next
The real value of modernisation is not just reaching go-live, it is creating the flexibility to keep improving afterwards.
When Asda separated from Walmart, it faced a highly complex technology transformation. Around 75% to 80% of its systems needed to change within three years, including warehouse management across 27 sites.
Together, Asda and Manhattan delivered a rapid programme of overnight conversions across a diverse estate. The work required multiple solution variants, careful change management and close collaboration between the two teams, but the goal remained simple: modernise the technology without destabilising the operation.
The result is a more configurable warehouse platform supporting Asda’s ongoing move from migration to optimisation. With the foundation in place, the focus is now on improving depot productivity, evolving replenishment and reducing cost to serve across the business.
Asda’s experience shows that warehouse modernisation is not only about replacing legacy systems. It is about building the resilience, flexibility and partnership needed to support the next stage of growth.
