Have you checked out the SCCM 2012 Beta yet? It is a big change from the SCCM 2007 for looks and feel of the program. They have gotten away from the mmc and actually have a console for this now. They have added a Migration part to it so you can migrate from your SCCM 2007 Site to SCCM 2012 and that actually works as I migrated my SCCM 2007 trial site I had going on here at work to the SCCM 2012 Beta with no issues. I did not have much going on with that site other than to remote control to the remote locations and the computers there with issues so it was not a real complicated move. The complicated part was learning where they moved everything in the new console. More on this later as I dig deeper into this.
Til later just Roger
