Munich finds Linux migration cost less than HP's analysis claims

Ja'Achan writes: Microsoft asked HP to analyse Munich's Linux migration, and HP found that the migration to Linux cost €60.6M, where if they had remained with Microsoft, it had only cost €17M. Now, Munich's City Council has objected against this analysis, which, among other assumed that Linux and Windows systems have "roughly the same hardware requirements". They found that the cost of migration was €23M, where if they had stayed with Microsoft, it would have cost them €34M.
