Tesco accelerates VMware exit amid Broadcom licensing dispute

UK supermarket chain Tesco is executing an aggressive migration away from VMware products following a licensing dispute with Broadcom, the company that acquired VMware in 2023. The retailer has filed a lawsuit alleging breach of contract and anti-competitive behavior, with proceedings scheduled to begin in the UK High Court in November 2027.

The conflict stems from a 2021 agreement in which Tesco purchased perpetual licenses for VMware’s vSphere Foundation and Cloud Foundation, along with subscriptions to Tanzu products. The deal included support and upgrades until 2026, with an option to extend for four additional years. Computacenter served as the reseller, and Dell acted as the distributor. At the time, Tesco also used Broadcom’s mainframe software and sought to extend support for those systems.

After Broadcom’s acquisition of VMware, the company shifted its licensing model, discontinuing standalone services for customers who did not adopt subscriptions for its bundled software. Broadcom refused to extend support for Tesco’s existing VMware estate, leading the retailer to file suit in mid-2025. Tesco claims Broadcom’s actions forced it to seek third-party support for its VMware infrastructure and accelerate a costly migration to alternative solutions.

Legal battle escalates

Tesco’s legal filings describe Broadcom’s conduct as abusive, arguing that the company leveraged its market position to impose unreasonable terms. The retailer states that it has incurred "material costs" to procure and migrate to alternative software, which it claims offers reduced functionality compared to VMware’s products. The migration timeline has introduced operational risks, including potential disruptions to store product ordering and payroll processing, which rely on Broadcom’s mainframe software.

Broadcom has made multiple offers to Tesco since the dispute began, including a "Strategic proposal" in July 2024 and separate terms for VMware and mainframe products in January 2026. Tesco rejected these proposals, with one April 2026 offer demanding $23.5 million (£17.4 million) for a year of VMware Cloud Foundation 9.0 and mainframe support—a 175% increase for VMware services and a 350% hike for mainframe products compared to Tesco’s 2021 contract. The retailer described the price increases as "manifestly unfair and excessive."

Broadcom’s defense argues that Tesco’s claims of damages are unfounded, as the retailer has since secured alternative suppliers. The company has previously stated its preference for shifting customers to its subscription-based Cloud Foundation (VCF) model, contending that perpetual licenses are outdated and less efficient. However, Tesco’s filings suggest skepticism toward this argument, framing Broadcom’s refusal to honor past agreements as the core issue.

Migration risks and industry trends

Tesco aims to complete its VMware migration by the end of 2027 but acknowledges the timeline is ambitious and fraught with risk. The retailer highlights compatibility issues with its existing backup and disaster recovery tools, Veeam and Zerto, which are not fully supported by the replacement virtualization platform. Data security and protection concerns have also been raised, given the critical role of virtualization in Tesco’s operations.

The case reflects broader industry unease with Broadcom’s post-acquisition licensing changes. Other enterprises, including Western Union, GEICO, and Computershare, have also reduced or eliminated their reliance on VMware products. Some VMware partners, such as Rackspace, have similarly scaled back their use of the platform. In Europe, Belgian school Scheppers Instituut Wetteren migrated to local provider Whitesky.Cloud to avoid a reported 400% price increase, completing the transition without new hardware.

What to watch

The UK High Court’s ruling, expected between November 2027 and February 2028, could set a precedent for how Broadcom’s licensing practices are scrutinized under competition law. Tesco’s case may influence other ongoing disputes, such as Siemens’ litigation against Broadcom, and shape enterprise strategies for managing vendor transitions. Meanwhile, the outcome of Tesco’s migration will serve as a test case for the feasibility of rapid VMware exits in large-scale environments.
