In one of the most consequential shifts in public sector IT policy of recent years, the German state of Schleswig-Holstein has initiated an unprecedented government-wide migration away from Microsoft software, targeting every desktop and digital process used by civil servants, police, and the judiciary. By September 2025, these public sector workers will have fully transitioned from Microsoft Teams, Outlook, Word, Excel, and the Windows operating system to open-source software, marking the largest such public initiative in Germany to date.
The scope and ambition of Schleswig-Holstein’s move is difficult to overstate. The first phase impacts 30,000 public workers across the state, while an additional 30,000 teachers are to follow in subsequent years. This is not a mere technology refresh but a decisive pivot away from reliance on US-based technology giants, underscored by rising geopolitical tensions and mounting EU concerns about strategic digital dependencies.
At the center of this transformation are robust, open-source alternatives: LibreOffice replaces Word and Excel, Open-Xchange takes over from Outlook, and the Linux operating system supplants Windows. The entire data infrastructure is similarly set for overhaul, with sensitive state information migrating from Microsoft Azure and other American-based cloud providers to a German-run public cloud managed within national borders.
This move is not occurring in isolation. The EU’s growing unease over digital dependencies has accelerated in recent years, particularly with the return of Donald Trump to the U.S. presidency and renewed transatlantic tensions. Concerns about vendor lock-in, data access, and surprise costs associated with proprietary software contracts have become ever more acute. In 2023, the European Commission launched an antitrust investigation into Microsoft over bundling practices, reinforcing a regulatory drive towards open standards and interoperability.
Schroedter likened the shift to lessons learned in energy security following the war in Ukraine: “The war in Ukraine revealed our energy dependencies. Now, we are confronting our digital ones.” This recognition of digital infrastructure as a strategic asset mirrors broader European trends emphasizing technological autonomy.
Schleswig-Holstein anticipates saving tens of millions of euros over the next several years, a projection supported by experience elsewhere—though it depends critically on implementation rigor and user support. Open-source advocates point to the inherent flexibility of non-proprietary software, which can be adapted to local needs without licensing constraints, supporting both operational resilience and budgetary predictability.
Successful migrations hinge on intensive training, clear communication, and robust technical support. Without these, resistance can harden among users who are understandably wary of any disruption to workflows and productivity. Change management becomes as crucial as the technology itself.
Elsewhere, local governments in Copenhagen and Aarhus, Denmark, are actively exploring alternatives to the Microsoft suite, while the movement to open-source digital infrastructure has found enthusiastic advocates in Spain, Italy, and South America. This transnational ripple is guided in part by the new Interoperable Europe Act, which came into force in 2024, compelling EU governments to prioritize open-source technologies for public administration. Benjamin Jean is optimistic: “We’ll start seeing real case studies that inspire wider adoption.”
The Act’s enforcement in 2024 has already catalyzed interest in policy circles and among IT leaders across the continent, spurring pilot programs and analytical studies to support member states during implementation phases.
Security is another major motivator. Proprietary software from foreign vendors exposes organizations to risks stemming from lack of transparency, foreign jurisdiction, and potential access by non-EU actors. Open-source platforms, in contrast, are subject to continuous scrutiny by a global pool of developers, narrowing the window for undiscovered vulnerabilities.
Cost savings, while attractive, are but one piece of a broader value proposition centering on flexibility, agility, and local control. Open-source adopters gain the ability to adapt, extend, and optimize systems based on real needs, without facing prohibitive relicensing fees or restrictive terms.
Finally, the shift signals adherence to fundamental EU values: openness, interoperability, and strategic technological self-determination.
Community-driven development is at the heart of open-source philosophy. The success of similar transitions—France’s gendarmerie, various municipalities in Spain and Italy, and myriad education and healthcare institutions—demonstrates that when governments actively contribute to upstream projects, they not only reap technical benefits but also influence feature sets and roadmaps to better align with public needs.
Critical analysis points to both significant potential benefits in cost, control, and compliance, and substantial risks involving user adaptation, technical integration, and political resolve. A successful implementation would undoubtedly bolster the argument for open-source in public administration, providing a ready-made blueprint for governments across Europe striving to reconcile efficiency with autonomy.
Whether Schleswig-Holstein’s bold new direction becomes a model for wider European adoption or an object lesson in the limitations of top-down digital transformation will ultimately hinge on careful execution, cultural buy-in, and the ability to evolve in the face of inevitable challenges. As the world watches, this German state is set to become the EU’s most ambitious laboratory for open-source government—and a crucible for the next phase of digital independence.

Unpacking the Schleswig-Holstein Migration: A Digital Sovereignty Milestone
The scope and ambition of Schleswig-Holstein’s move is difficult to overstate. The first phase impacts 30,000 public workers across the state, while an additional 30,000 teachers are to follow in subsequent years. This is not a mere technology refresh but a decisive pivot away from reliance on US-based technology giants, underscored by rising geopolitical tensions and mounting EU concerns about strategic digital dependencies.At the center of this transformation are robust, open-source alternatives: LibreOffice replaces Word and Excel, Open-Xchange takes over from Outlook, and the Linux operating system supplants Windows. The entire data infrastructure is similarly set for overhaul, with sensitive state information migrating from Microsoft Azure and other American-based cloud providers to a German-run public cloud managed within national borders.
The Political and Technical Imperative
Schleswig-Holstein’s motives are multifaceted. The state’s Digitalization Minister, Dirk Schroedter, has been unequivocal in framing the migration as both an assertion of data sovereignty and an economically prudent choice. Speaking in a video call—deliberately conducted over a German-built open-source platform—Schroedter declared, “We’re done with Teams,” encapsulating a sense of finality and resolve.This move is not occurring in isolation. The EU’s growing unease over digital dependencies has accelerated in recent years, particularly with the return of Donald Trump to the U.S. presidency and renewed transatlantic tensions. Concerns about vendor lock-in, data access, and surprise costs associated with proprietary software contracts have become ever more acute. In 2023, the European Commission launched an antitrust investigation into Microsoft over bundling practices, reinforcing a regulatory drive towards open standards and interoperability.
Schroedter likened the shift to lessons learned in energy security following the war in Ukraine: “The war in Ukraine revealed our energy dependencies. Now, we are confronting our digital ones.” This recognition of digital infrastructure as a strategic asset mirrors broader European trends emphasizing technological autonomy.
Economic Rationale: Projected Savings and Enhanced Flexibility
Beyond sovereignty, the economics of the migration offer compelling incentives. Microsoft’s enterprise contracts, which often feature opaque fee structures and compulsory periodic upgrades, can lead to unexpected spikes in IT expenditure. Benjamin Jean, founder of the consultancy Inno3, summarizes the peril succinctly: “When hit with surprise costs for updates, organizations feel cornered.” As organizations embrace open-source platforms, they eliminate the looming threat of vendor lock-in and unpredictable price escalations.Schleswig-Holstein anticipates saving tens of millions of euros over the next several years, a projection supported by experience elsewhere—though it depends critically on implementation rigor and user support. Open-source advocates point to the inherent flexibility of non-proprietary software, which can be adapted to local needs without licensing constraints, supporting both operational resilience and budgetary predictability.
Technical Architecture: What Replaces Microsoft’s Suite?
The technological backbone of the transition is anchored by several proven open-source solutions:- LibreOffice: A feature-rich office suite encompassing word processing, spreadsheets, and presentations, extensively adopted by educational and government bodies worldwide.
- Open-Xchange: A European-developed platform providing email, calendar, and collaboration tools as a direct replacement for Outlook.
- Linux: As the operating system of choice, Linux offers both stability and security, with a global developer community continuously auditing and enhancing the platform.
- German Public Cloud: Data migration to local cloud infrastructure ensures compliance with EU and federal data privacy regulations, a move expected to bolster trust among both citizens and officials.
Migration in Practice: The Roadblocks and Risks
However, history tempers enthusiasm. Earlier German initiatives, most notably in Munich, serve as cautionary tales about the complexity and risks inherent in large-scale IT transitions. Munich originally blazed a trail for open-source adoption, only to return to Microsoft in 2017 after enduring years of political shifts, inconsistent organizational support, and staff discontent. François Pellegrini, IT professor at Bordeaux University, underscores the core challenge: “If staff aren’t properly supported, they’ll want to go back to the old systems.”Successful migrations hinge on intensive training, clear communication, and robust technical support. Without these, resistance can harden among users who are understandably wary of any disruption to workflows and productivity. Change management becomes as crucial as the technology itself.
A Growing Movement: Continental and Global Ripples
Despite Munich’s setback, Schleswig-Holstein’s project is not an isolated gamble. Across Europe and beyond, momentum for open-source adoption in the public sector is gathering pace. France’s national police force, the gendarmerie, has used Linux for over two decades, reaping sustained cost savings and digital resilience. In 2023, India’s Ministry of Defence unveiled Maya OS, its own secure operating system designed to replace Microsoft Windows on thousands of government workstations.Elsewhere, local governments in Copenhagen and Aarhus, Denmark, are actively exploring alternatives to the Microsoft suite, while the movement to open-source digital infrastructure has found enthusiastic advocates in Spain, Italy, and South America. This transnational ripple is guided in part by the new Interoperable Europe Act, which came into force in 2024, compelling EU governments to prioritize open-source technologies for public administration. Benjamin Jean is optimistic: “We’ll start seeing real case studies that inspire wider adoption.”
Regulatory Backdrop: The Interoperable Europe Act and EU Priorities
A defining component of the EU’s digital strategy, the Interoperable Europe Act, constitutes a legal and policy bedrock for the Schleswig-Holstein transition. The Act mandates that public sector bodies embrace open standards and seek out open-source alternatives whenever feasible. Its goal is twofold: to ensure interoperability between digital services across member states and to reduce structural reliance on any single vendor. By prioritizing collaborative, open standards, the Act augments both cross-border cooperation and cyber resilience.The Act’s enforcement in 2024 has already catalyzed interest in policy circles and among IT leaders across the continent, spurring pilot programs and analytical studies to support member states during implementation phases.
Strengths: Autonomy, Security, and Adherence to EU Values
Several strengths underpin Schleswig-Holstein’s strategy. First and foremost is the reclamation of digital autonomy. By deploying open-source code and retaining data on German soil, the government directly addresses data privacy, security, and compliance requirements set forth by the EU General Data Protection Regulation (GDPR) and further echoed in German federal guidelines.Security is another major motivator. Proprietary software from foreign vendors exposes organizations to risks stemming from lack of transparency, foreign jurisdiction, and potential access by non-EU actors. Open-source platforms, in contrast, are subject to continuous scrutiny by a global pool of developers, narrowing the window for undiscovered vulnerabilities.
Cost savings, while attractive, are but one piece of a broader value proposition centering on flexibility, agility, and local control. Open-source adopters gain the ability to adapt, extend, and optimize systems based on real needs, without facing prohibitive relicensing fees or restrictive terms.
Finally, the shift signals adherence to fundamental EU values: openness, interoperability, and strategic technological self-determination.
Challenges: Managing Complexity and Maintaining Momentum
Nonetheless, formidable risks accompany such ambition.- User acceptance: As Munich’s experience confirms, resistance among staff can derail even the best-intentioned plans. Usability, training, and clear demonstration of open-source tools’ advantages are non-negotiable.
- Technical integration: Many legacy systems and specialized applications are tightly interwoven with Microsoft platforms. Ensuring that open-source software interfaces smoothly with business-critical workflows entails significant development and troubleshooting resources.
- Support and maintenance: Proprietary vendors typically offer extensive, integrated support. By transitioning to open-source, organizations either develop internal capacity or contract third-party providers, both of which require upfront investment and strategic foresight.
- Upgrades and compatibility: While open-source software is renowned for flexibility, lack of uniformity across versions and distributions can introduce complications, particularly in large, complex environments.
Lessons from Precedent and the Role of Community
The success or failure of Schleswig-Holstein’s endeavor will resonate far beyond its borders, shaping policy discourse and technical roadmaps throughout the EU and beyond. The project’s visibility ensures a wealth of real-world data on user satisfaction, total costs of ownership, and security outcomes.Community-driven development is at the heart of open-source philosophy. The success of similar transitions—France’s gendarmerie, various municipalities in Spain and Italy, and myriad education and healthcare institutions—demonstrates that when governments actively contribute to upstream projects, they not only reap technical benefits but also influence feature sets and roadmaps to better align with public needs.
A Watershed for European Digital Sovereignty
The strategic pivot in Schleswig-Holstein is more than an IT overhaul—it is a deliberate affirmation of European digital sovereignty and policy innovation. As EU member states reckon with new regulatory imperatives and a volatile geopolitical landscape, the appetite for open-source alternatives is only expected to grow.Critical analysis points to both significant potential benefits in cost, control, and compliance, and substantial risks involving user adaptation, technical integration, and political resolve. A successful implementation would undoubtedly bolster the argument for open-source in public administration, providing a ready-made blueprint for governments across Europe striving to reconcile efficiency with autonomy.
Whether Schleswig-Holstein’s bold new direction becomes a model for wider European adoption or an object lesson in the limitations of top-down digital transformation will ultimately hinge on careful execution, cultural buy-in, and the ability to evolve in the face of inevitable challenges. As the world watches, this German state is set to become the EU’s most ambitious laboratory for open-source government—and a crucible for the next phase of digital independence.
