SBS2003 -> SBS 2011 migration: Exchange 2003 uninstall fails


Working my way through the Microsoft steps to migrate from SBS2003 to SBS2011. Everything has gone smoothly up to the point of removing Exchange 2003 before demoting the server. When I ran through the first time, it failed due to a service not responding in a timely fashion. Now when I go back through to try again I get constant pop-ups that the NNTP component of IIS is not installed. I've seen the next step is manual removal and have that article.

My question: If this server is being retired immediately and will not be used for anything further, is it possible to just continue on without fully uninstalling the old Exchange?

You probably should decommission it. Check out this Petri arcicle.

Anytime i migrate, i leave Exchange 2003 installed, but shut down the server or services for a week or so to make sure i didnt miss anything. Then after i am confident that it can be removed, i get rid of it.
