Executive Summary

The state of Berlin plans a gradual transition of its administration from Windows and Microsoft Office to Linux and open-source software by the end of 2025. The project includes training, workshops, and consultation hours to prepare government agencies. To date, implementation has been limited to a few pilot projects within individual administrative units, and a complete transition is not foreseeable. In parallel, the federal government and states are supporting the Center for Digital Sovereignty of Public Administration (Zendis), which is intended to develop open-source solutions for the state. Implementation is progressing slowly: Zendis was equipped with only nine employees in 2024 and was not promised a fixed budget.

The debate over technological independence from US corporations is gaining momentum under the Trump administration – yet Germany's response remains fragmented and underfunded. While France and Schleswig-Holstein are implementing concrete migration projects, Germany lacks a federal overall strategy with binding objectives. With potential annual savings of nearly 500 million euros through abandoning Microsoft licenses, the economic viability is obvious, yet the federal government and states are acting in isolation rather than in coordination – a pattern that systematically undermines central IT sovereignty.

Detailed Summary

Berlin's approach to open-source migration focuses on capacity building: training and workshops are intended to facilitate the switch to various open-source programs for government employees. Cultural change plays a subordinate role – the goal is for government agencies not only to use open-source software but to actively participate in its further development. However, the project remains vague: concrete pilot projects are in planning, and full implementation by the administration is far in the future.

The Center for Digital Sovereignty (Zendis) is intended to serve as an overarching coordination body. The Opendesk project aims to replace multiple proprietary solutions from Microsoft, Google, and Apple with a single sovereign platform – with email client, word processing, conference software, and cloud file management. However, reality shows massive resource bottlenecks: a parliamentary inquiry by politician Anke Domscheit-Berg (Left Party) revealed that Zendis operated with just nine employees in early 2024 and received only a single contract for the Opencode project. Even before its establishment, the center was not promised a fixed budget. First tests by the German Pension Insurance and Employment Agency will follow in 2026, but funding ends on April 30 – without a clear evaluation perspective.

Schleswig-Holstein proved that larger migrations are feasible. Nevertheless, there is no federal deadline or coordination obligation. States develop in isolation, which is expensive and inefficient. An alternative would be targeted support for German software companies to develop data protection-compliant open-source solutions – this would reduce government spending and strengthen domestic tech ecosystems.

Key Statements

  • Berlin is planning an open-source migration in administration but to date is only implementing test pilots without a binding roadmap.
  • The federal system leads to redundancies and inefficiency; there is a lack of a nationwide overall strategy with a deadline.
  • Zendis is chronically underfunded (9 employees in 2024, no fixed budget) and cannot fulfill its bridge-building role.
  • Estimated 500 million euros in annual savings through license cost reduction justify significantly higher investments in sovereignty.
  • Parallel development by states is more expensive than a central program with technology transfer to SMEs.

Critical Questions

  1. Evidence/Data Quality: How was the estimate of 500 million euros in savings calculated, and what specific license agreements and terms does it refer to?

  2. Evidence/Data Quality: What technical and security requirements did Opendesk meet during tests by the German Pension Insurance, and what are the test results to date?

  3. Conflicts of Interest/Incentives: What incentives do federal states currently have to stop expensive individual development and invest in a central Zendis budget?

  4. Conflicts of Interest/Incentives: To what extent did Microsoft or other software companies have influence on the delayed budgeting and lean staffing of Zendis?

  5. Causality/Alternatives: Could Schleswig-Holstein have implemented its migration plan faster without federal isolation, or were local factors decisive?

  6. Causality/Alternatives: What scenarios were examined to weigh the costs of the status quo (Microsoft dependency + data security risks) against migration?

  7. Feasibility/Risks: What organizational and technical hurdles emerged in previous pilot projects, and how do training concepts address employee resistance?

  8. Feasibility/Risks: How will it be prevented that the April 30, 2026 funding for Opendesk tests expires without further follow-up obligation and the project fails again?
