Windows to Linux Migration in the Enterprise?

youngerpants asks: "There is a lot of talk at the moment about migrating applications from WIN32 to Linux. This certainly helps move the OSS movement along, however, the true test of Linux is in the enterprise. Whereas we can move applications, how can the enterprise itself (such as Active Directory to Open LDAP, Exchange Server to Sendmail and NTFS to Samba) be moved. Have Slashdot readers used any applications or followed any strategies to migrate their enterprise? How would you tackle an obviously risky migration?"

Alot of talk, little real activity

The only places that can really migrate to Linux en-masse are places like call-centers where computers are used for specific and rigid purposes.

Larger enterprises look at and think about the "savings", but when you compare the training costs, hassle and resistance that most users will feel, you're not saving anything.

The places that have successfully transitioned to Linux (federal labs, Burlington Coat Factory, City of Largo, small companies) were either established Unix shops already or started with small or completely disorganized IT organizations.
