For the record, I want to basically start from scratch with my SCCM hierarchy. Quite possibly I might be overthinking it, but if the existing 2007 SCCM clients are associated with the 2007 site they wont talk to the 2012 Primary site...right? The boundaries are going to be the same between 2007 and 2012 (via IP subnet). So as far as the client upgrade method, I'm not sure what will be the best method. Maybe via Group Policy or login script since I dont want to keep the 2007 server online longer than I need to.
Opinions???
