About eight months ago, I took over as Network Administrator for a non-profit organization. So please bear with me. I've maintained plenty of environments, but haven't had the pleasure of doing major upgrades -- (I guess I've been lucky/cursed with well maintained environments in the past). So this is new terrain or me, and I need some help. The last thing I want to do is blow up our mail.
Putting it simply, we have Exchange Server 2007 running on a Server 2003 SP2 box.
My understanding is that you can not do an in place upgrade to the same box in this scenario, so I've built a new Server 2008 R2 SP1 VM, and intend on installing Exchange Server 2010 onto it.
Now, I've been searching for information on the web on exactly what the best practices approach would be in this case, and have even used the Exchange Server Deployment Assistant. Unfortunately, and much to my surprise, I'm not seeing a whole lot of resources on how to do what I'm trying to do. It's either upgrading Exchange 2007 to 2010 on an existing 2008 R2 Server, or building from scratch.
What I really need (for expediency and accuracy) is a step by step guide on how to drag us out of the now expired world of Server 2003, migrate our exchange, and all of this without impacting users.
