The city of Munich has switched its administration and day to day businesses to use open source software. The transition process has lasted for ten years and is a complete success. The city migrated from Windows NT to LiMux, its own Linux distribution. The city also decided to use the Open Document Format (ODF) as a standard, instead of proprietary options.

According to last year's results, the switch has saved more than 11.7 million euros for the city. This project is proof that the use of open-source software is possible in highly complex business environments. More information is available onCIO.
