What is the proper method of upgrading from Server 2003 to server 2008 in a 3-AD server setup?
Posted on 2008-06-12
I have three servers, one is our File and print share DC, one is our secondary DC, and the other is our exchange server. I would like to upgrade to server 2008 from (all of them being) server 2003. What is the best way to do it?? (Especially with Active Directory!) Is it best to bring them all up to 2008 at the same time? Or is it best to bring one up, another one the next week and the third one a week after that?? What's the proper/recommended way to complete this?
