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.
