I find myself tasked with organizing an upgrade of our entire Active Directory from server 2003 to 2008. We run a few AD dependant services such as

Exchange 2007
SQL Server 2008
SharePoint 2007

All of which we are looking to bring up to date as well with their most recent versions. The original AD was a little bit of a mess (the exchange upgrade from 2003 left some stuff in the AD database that I make references to servers that no longer exist for example).

Here is what I want to accomplish

Migrate the domain from our 2003 to a NEW clean 2008r2 domain
Upgrade from Sharepoint 2007 to 2010
Upgrade Exchange from 2007 to 2010

My question is, in what order do we do things? Can I do a domain upgrade and simply migrate exchange after? On their own, these objectives are complicated enough, orchestrating them in our company while minimizing downtime is making my head spin. I have done a lot of the research on how to do them individually but I am having trouble figuring out how to do them all in concert.
