Why a German State Is Ditching Microsoft

Hamzah·24 October 2025

A Bold Move

In a bold move challenging the dominance of proprietary software in the public sector, the German state of Schleswig-Holstein has announced plans to migrate its 30,000 computers away from Microsoft Windows and Office. In their place, the state plans to adopt open-source alternatives: the Linux operating system and the LibreOffice suite.

This isn't just a software swap - it's a strategic shift grounded in sovereignty, security, and cost-efficiency.

The Motives: More Than Just Saving Money

Led by Minister-President Daniel Günther, the decision is driven by several key priorities:

Digital Sovereignty and Independence: Relying on a single foreign company for critical infrastructure creates dependency. Open-source software gives the state more control: it can audit code, customise systems, and avoid vendor lock-in.

Data Protection and Security: Open-source transparency allows security vulnerabilities to be identified and addressed by a global community. While this does not automatically make systems completely secure, it provides opportunities for better auditing compared with proprietary software.

Cost Efficiency: Migration requires investment in training, support, and possible compatibility fixes. However, eliminating recurring licensing fees for Microsoft products could result in long-term savings, as LibreOffice and Linux have no licensing costs.

Interoperability and Open Standards: By adopting open file formats like ODF (OpenDocument Format), government documents remain accessible and readable long-term, reducing vendor lock-in and preserving access to public records.

What Are They Switching To?

The transition is planned as follows:

  • Windows → Linux: Microsoft's Windows OS will be replaced by a Linux distribution. The specific version has not been officially confirmed.
  • Microsoft Office → LibreOffice: Word, Excel, and PowerPoint will be replaced by LibreOffice's Writer, Calc, and Impress, providing functional equivalents for civil servants.

A Pioneering Step

Schleswig-Holstein is not the first German government to attempt this shift - Munich's LiMux project attempted a similar migration years ago. Its comprehensive, top-down approach is ambitious, but its success will determine whether it can serve as a model for other governments.
