Tesco has launched one of the largest known migrations away from VMware, revealing plans to move around 40,000 server workloads off the virtualisation platform as its legal battle with Broadcom intensifies.
The UK supermarket giant is seeking more than £100 million in damages from Broadcom, accusing the technology company of unfair business practices following its acquisition of VMware. Court filings claim Tesco has been forced to accelerate its departure from the platform after facing steep increases in software costs and significant changes to licensing arrangements.
According to reports, Tesco purchased perpetual VMware licences in 2021 that included support and updates through 2026, with an option to extend support for several more years. However, after Broadcom completed its takeover of VMware, the retailer alleges that support options changed and that it was pushed toward a subscription-based model at substantially higher prices. Tesco claims the changes resulted in cost increases of roughly 175 per cent.
The retailer argues that virtualisation technology is critical to its operations, supporting thousands of workloads across stores, logistics networks, and other business systems. In legal filings, Tesco said it had been forced to invest in alternative solutions and third-party support services while planning a large-scale migration away from VMware. The company also warned that moving such a vast infrastructure on an accelerated timetable carries operational risks.
Industry analysts have noted that VMware customers across multiple sectors have been reassessing their technology strategies since Broadcom’s acquisition. Concerns over pricing, licensing changes, and long-term vendor dependence have prompted some organisations to explore alternative virtualisation platforms. Research cited by industry observers has suggested that a significant number of customers are actively reducing their reliance on VMware technologies.
Despite those concerns, experts say large-scale migrations remain complex and expensive undertakings. Gartner estimates that major enterprise moves involving thousands of virtual machines can take several years to complete, highlighting the scale of Tesco’s project.
Tesco aims to complete its migration by the end of 2027, making the initiative a closely watched test case for other enterprises weighing the costs of staying with VMware against the challenges of moving elsewhere. The outcome of its lawsuit could also have broader implications for customers affected by Broadcom’s post-acquisition licensing strategy.
