I currently manage a network with a single NT Domain with servers running a mix of NT4 & Windows 2000. Of late, I found myself spending a lot of money to keep pace with Microsoft licenses schemes and I am looking for a way to cut costs.
I would like to move my critical services (file, print, Proxy, Firewall) to Linux and ultimately, replace my entire domain with one secured and managed by Linux.
Is this possible? How would I go about even planning a major migration like this? Can Linux & Windows co-exist on the same network?
