hi ,

I have SCCM 2007 already installed in my environment , i want to install new machine with SCCM 2012 and deploy the new 2012 client to the pcs , what are the requirements of such installation:

-Do i have to uninstall old clients from the PCs ?

-Do i have to extend the active directory schema ?

-Do i have to delete the container and create new one for 2012 ?

please help

Clients will be upgraded automatically (if you push or install them using whatever method fits best). No need to extend the schema again. Container should be cleaned up only (remove CM07 objects) and add permissions for the new site.

Check these links. they are quite useful for migrating SCCM 2007 to SCCM 2012.
