Recently went through the process of migrating all our desktop clients to 2012. Curious if anyone has had any experience properly shutting off 2007. From my research, I was planning on uninstalling Config. Mgr. 2007 on the old server, and putting in a ticket to the server team remove the old 2007 containers in the Systems Management OU from ADSI edit (see image). Is this required or needed? Or can I just nuke the server?
