Fidelity Investments successfully migrated over 50,000 state files from Terraform to OpenTofu, demonstrating that such a transition, with the right planning and strategy, is more of an organizational challenge than a technical one. The migration was driven by HashiCorp's shift to BSL licensing, prompting Fidelity, committed to open-source principles, to align with the community-driven OpenTofu under the Linux Foundation. Fidelity's approach involved a six-phase strategy focusing on rigorous proof of concept, lighthouse projects, consensus building, developer enablement, progress tracking, and a default switch, without requiring extensive code rewrites due to OpenTofu's compatibility with Terraform. This process emphasized the importance of organizational factors such as stakeholder engagement and infrastructure adaptation over technical challenges, with Fidelity actively contributing to the OpenTofu community to shape the future of infrastructure automation.
