I am working with a customer that is upgrading their entire corporation to Windows 7. There is about a 60/40 split when it comes to upgrade vs. refresh. The company is also in the process of migrating to a brand new Active Directory domain that is Server 2008 R2 native. The question I have is what is best practice, upgrading and refreshing the users to Windows 7 then migrating them to the new domain, or is it better to upgrade and refresh and at the same time migrate them to the new domain during the process. I am having trouble finding this senario in any documents. The customer is using Quest tools to handle the migration from the existing domain to the new domain and all GPO's will be setup as new in the target domain. SCCM 2007 is also deployed in the target domain.
