Embracing Digital Sovereignty: The Shift from Windows to Linux in Government Ministries
The recent directive from France’s Interministerial Digital Directorate (DINUM) to migrate government workstations from Windows to Linux has sent shockwaves across the digital landscape. This move is part of France’s efforts to assert its digital sovereignty, reducing its reliance on foreign technology and promoting the use of domestic solutions. As a result, government ministries are now scrambling to develop plans to eliminate extra-European digital dependencies by autumn 2026. In this article, we will delve into the reasons behind this shift, the challenges that come with it, and provide practical advice on how to successfully migrate from Windows to Linux.
Understanding the Need for Digital Sovereignty
Fears of foreign interference and the potential risks associated with relying on foreign technology have led many governments to reevaluate their digital strategies. France, in particular, has been at the forefront of this movement, recognizing the need to develop a robust digital ecosystem that is controlled and secured by its own citizens. The country’s January 2026 mandate to replace Microsoft Teams and Zoom with its domestic Visio platform across 2.5 million civil servants is a testament to its commitment to digital sovereignty.
The Benefits of Migrating to Linux
Linux, an open-source operating system, offers numerous benefits that make it an attractive choice for government ministries. For one, it is highly customizable, allowing users to tailor the system to their specific needs. This flexibility is particularly valuable in a government setting, where different departments may require different software configurations. Additionally, Linux is more secure than Windows, with a lower risk of malware and viruses. This is especially important for government agencies, where sensitive information is often handled.
Another significant advantage of Linux is its cost-effectiveness. By abandoning Microsoft licensing fees, government ministries can save millions of euros annually. In fact, the Gendarmerie nationale, France’s national police force, has estimated that its switch to Linux has saved around two million euros per year in licensing costs and reduced the total cost of ownership by an estimated 40%.
Phased Migration: The Key to Success
While the benefits of migrating to Linux are clear, the process itself can be complex and daunting. To ensure a smooth transition, government ministries must adopt a phased approach. This involves breaking down the migration into smaller, manageable tasks, such as:
- Assessing current software and infrastructure
- Developing a customized Linux distribution
- Training staff on Linux operations
- Migrating data and applications
- Implementing security measures
By taking a phased approach, ministries can avoid overwhelming their IT teams and minimize the risk of disruptions to critical services. This strategy also allows for the gradual development of internal competencies and governance structures, ensuring that the transition is sustainable and long-term.
Lessons from the Gendarmerie Nationale
The Gendarmerie nationale’s experience with Linux provides valuable lessons for government ministries embarking on a similar journey. By launching GendBuntu, its customized Ubuntu-based deployment, in 2008, the Gendarmerie was able to build the internal competencies and governance structures required for a full operating system switch. Today, GendBuntu runs on 103,164 workstations, representing 97% of the force’s computing estate.
The financial outcome of this shift has been impressive, with the Gendarmerie saving approximately two million euros per year in licensing costs and reducing the total cost of ownership by an estimated 40%. This success story serves as a testament to the feasibility and benefits of migrating to Linux, even for large-scale government agencies.
International Context: Germany’s State of Schleswig-Holstein
The German state of Schleswig-Holstein provides another compelling example of the benefits of migrating to Linux. In 2024, the state began its own Microsoft-to-Linux transition, which has yielded impressive results. By early 2026, nearly 80% of the state’s 30,000-workstation migration was complete, with recorded savings of €15 million in licensing costs in 2026 alone.

These examples demonstrate that a phased migration approach, combined with coherent governance and internal competencies, can lead to significant cost savings and improved security. As more governments explore the possibility of migrating to Linux, these case studies will serve as valuable guides and inspirations.
Practical Advice for a Smooth Transition
So, how can government ministries ensure a smooth transition to Linux? Here are some practical tips to keep in mind:
- Establish a dedicated project team to oversee the migration
- Develop a detailed project plan and timeline
- Choose a suitable Linux distribution and customize it to meet your needs
- Provide comprehensive training for staff on Linux operations
- Implement robust security measures to protect sensitive information
By following these tips and adopting a phased approach, government ministries can successfully migrate from Windows to Linux, reducing their reliance on foreign technology and promoting digital sovereignty.
Conclusion
The shift from Windows to Linux in government ministries is a significant step towards digital sovereignty. By embracing open-source technology, governments can reduce their reliance on foreign technology, improve security, and save millions of euros in licensing costs. The examples of the Gendarmerie nationale and the German state of Schleswig-Holstein demonstrate that a phased migration approach can lead to remarkable success. As more governments explore the possibility of migrating to Linux, it is essential to remember the importance of internal competencies, governance structures, and robust security measures.
With careful planning, execution, and a commitment to digital sovereignty, government ministries can successfully transition to Linux, paving the way for a more secure, cost-effective, and sustainable digital future.
