The state of Schleswig-Holstein in Germany has successfully migrated to open-source software, saving 15 million euros in license costs. The state administration has switched to LibreOffice, an open-source office software, and plans to convert the remaining 20% of workplaces that still use Microsoft programs. The migration is seen as a significant step towards digital sovereignty and independence from proprietary software vendors. The state expects to save millions of euros in the coming years.
