jkirshy Posted April 10, 2013 Report post Posted April 10, 2013 (edited) I have a Sccm 2007 server running live and doing a side by side install of Sccm 2012 Sp1. I have stopped the sms_executive service on sccm 2007. The only ad entries are from sccm 2012 live server. I have some automatic install of the sccm 2012 client, but most clients just wont install, the ccmsetup.exe does not even start on the client machine? This is driving me nuts! Ok months later sccm 2012 is running fine. On sccm 2007 migrate over as many clients as possible. Re-create your software packages. Uninstall sccm 2007, delete ad info on sccm 2007. .
