Migration

Maybe with a little more specifics. How many users? How many workstations and or servers? Have you considered the learning curve for your users? Do you and your users know that most of the software they may have been using will no longer be available to them? There needs to be a lot more thought and planning when doing a Migration, sorry I am really not trying to assume there is no thought or planning, but this question is so vague that it is really hard to be of much help.

In a nutshell I suppose you could just start with one client at a time, as this will keep your network up for a bit, and then start working on the servers. Maybe even to the extent of starting with fresh hardware for your servers and integrating them into ourexisting network and then pull the old servers out, sell them or install Linux on them and use them to help divide up the work load.
