Spiegel has a piece about a department manager’s view of the migration. The guy is 60+ and worked 20 years with computers before migrating to GNU/Linux. Some details:
- The major problem he encountered were some duplicated records in a database. These were eventually fixed.
- 22 CMS (Content Management Systems) were rolled into one.
- Cost was not so much a priority as efficiency.
- 300 applications had to be replaced.
- 50 people did the migrating work.
- Only 10% of machines needed to keep that other OS as no simple replacement could be found for some applications on GNU/Linux.
- To date 6900 PCs have been migrated.
- By 2013 it is expected that 12000 of 15000 PCs will be GNU/Linux-only.
- Heavy use will be made of web-applications to facilitate future changes to the system.
On a lighter note, a councillor asked hard questions about going back to that other OS but the mayor promised to stay the course.
So the FUD about the Munich Migration being a disaster of some kind is not real. They are doing much more than migrating to another OS at the same time by rationalizing IT in other ways (CMS and web-applications) and they are not in any hurry crunching 50-100 per week and likely doing some hand-holding at the same time. It works for them.
