Windows to Linux migration guide
George Ou points out this excellent crash course guide by Chris Walden of IBM for any Windows administrator that’s either migrating to Linux or would like to learn more about working with Linux. If you’re a Windows administrator it doesn’t matter if you’re actually migrating or not because at some point you’re going to have work with Linux on some device or other so this is a great way to get your feet wet. It tries to take what you already know and apply it to Linux.
