The Woes of Munich's Linux Migration

mikrorechner writes "The H Online has a writeup of the problems encountered by LiMux (Wikipedia entry), one of the most prominent Linux migration projects in the world, trying to introduce free software into the highly heterogenous IT infrastructure of the City of Munich. Quoting: 'Florian Schiessl, deputy head of Munich's LiMux project for migrating the city's public administration to Linux, has, for the first time, explained why migrating the city's computing landscape to open source software has taken longer than originally planned.'" Here is Shiessl's blog, in which he details some of the transition problems.

Re:Because every project is late

[WrongSizeGlass]

Indeed.

Every major project always takes longer than expected because so many small details are exposed as you uproot any existing system or workflow process. Instead of looking at this as something that may have been "more trouble than they bargained for" we should learn from it and understand that migrating to Linux won't be any easier than migrating to or from any other platform. I think there are two things to take away from Munich's Linux migration:
* It can be done.
* Being on the leading edge carries with it a lot of responsibility to those who will follow you.

Wrong approach

[Sub Zero 992]

Well, they tried a horizontal migration strategy, moving from location to location and department to department. That meant the problems never stopped.

A better approach might have been to do a vertical top-down migration: Servers: first roll out a directory server infrastructure, then a CIFS strategy etc.; Clients: migrate away from MSIE / Active X, then to CUPS, then away from MS Office etc.. And then, finally, to change the desktop OS out from underneath.

A suggested strategy for those planning something similar: 1: migrate the server services (and create a shiny new unified and consistent infrastructure); 2: migrate the desktop apps to FOSS alternatives (chose apps which will work under your target desktop OS); 3: switch out the desktop OS for linux (the users retain the apps they have become used to).

And then, finally, to change the desktop OS out from underneath.

They seem to have taken a more blended approach. A separate project was revamping many of the servers at the same time. They did immediately move away from MS Office to OpenOffice and ODF because they could do so without having to worry about the servers and they laud it as one of the biggest benefits so far. I don't know of any good reason why they should have held off on that. The problem with a top down migration is that many times you don't know what all the services inside your organization and out are actually used. So rolling out a series of Linux clients in every department allows you to discover what your platform specific dependencies are. In some cases they changed the Linux client to work with those services and in some they changed the services to work with Linux.

A suggested strategy for those planning something similar: 1: migrate the server services (and create a shiny new unified and consistent infrastructure);

The problem here is in your first step you may have broken a bunch of things and users will have to start changing the way they work. From their perspective you've downgraded the system. That's because they're using a client that does not work as well with your new servers as your Linux clients will. So you've just given the majority of your users a bad taste for the whole thing and generated tons of pushback that can kill your whole migration.

I think it would make more sense to switch to as many platform agnostic applications as possible, first. Then implement the servers and desktops simultaneously in one part of the company, while letting the users have access to their old desktop via a remote session. Fix the compatibility problems and move on to the next chunk of the company until you can start repurposing the old servers and getting rid of the remote desktop sessions altogether.

Re:Bad title is bad.

Very true, by the sound of the blog most of their problems stem from how poorly the systems were managed before. Different versions of Windows running different levels of updates; hundreds of authorized apps, many with overlapping or duplicate functionality; unauthorized applications that had made their way into the work-flows without being documented; proprietary software that didn't follow open standards. I wonder how much of their effort has gone into just getting their infrastructure should have been before the transition even started.

Why so prominent?

[Mark_in_Brazil]

Why is the Linux migration project in Munich so prominent, as mentioned in TFS? I know of much larger migrations, both in terms of the number of computers and the geographic area covered. The Brazilian government has been migrating to Free Software in mass. The Bank of Brazil, for example, has over 100,000 computers running Firefox and BrOffice. As of last June, the estimate was right at 100,000, with 65,000 of those machines running Linux and 35,000 running other operating systems. The Bank of Brazil has branches and offices all over Brazil, which is a very large country. The mass migration happened in 2006, before the migration really began in Munich. The number of machines involved (counting the Linux boxes only) is about 5 times as large as the number of machines to be involved in Munich, and instead of being located in a single city, they are spread out all over a country that's larger than the US would be if it didn't have Alaska, but smaller than the US with Alaska (i.e., larger in area than the "lower 48" plus DC plus Hawaii). In the year 2006 alone, the Bank of Brazil estimated that it saved R$20MM by using Free Software.

FWIW, I've also seen Linux desktops at the ITI (Brazil's IT Institute). Even totally non-nerdy ITI employees seemed perfectly at home on Linux desktops when I was there as long ago as early-to-mid 2005. The Bank of Brazil branch where my company has its account has all Linux desktops. The managers who take care of my account think it's funny when I crane my neck to look at their monitors and geek out on the software their 'puters are running. They are total non-nerds and not only appear to be happy with the Linux desktops, but told me they are. It took them a minute to figure out what I was asking - they didn't think of using Linux desktops as anything all that unusual.
