T-Mobile is migrating its extensive VMware infrastructure to an alternative platform while simultaneously pursuing legal action against Broadcom regarding the terms of its software support rights. According to reports from Slashdot and Ars Technica, the migration involves a significant portion of T-Mobile's internal network, which currently utilizes approximately 303,000 cores.
The legal dispute centers on whether Broadcom is obligated to provide "extended support" for existing perpetual licenses. The Register reports that this conflict follows Broadcom’s acquisition of VMware, and it reflects a struggle over how the company manages legacy contracts. T-Mobile claims its current agreements guarantee these rights, which it seeks to maintain as it transitions its systems off the platform.
Ars Technica reports that tens of thousands of virtual machines are being moved during this process. The scale of the migration highlights the size of T-Mobile's infrastructure and its effort to secure operations while the legal proceedings regarding its contract with Broadcom continue. By relocating these assets, T-Mobile aims to establish a more stable environment for its network while the litigation over its rights under original license agreements remains in court.
Why this matters
This case highlights the friction between large enterprise customers and new owners of legacy software systems following major corporate acquisitions. It illustrates how contract disputes regarding support terms can drive significant infrastructure decisions for critical telecommunications providers.
