I have been running a 2007 sccm for a while and have now set up a brand new server with sccm 2012. I've migrated the collections and created the boundaries so all machines should be found at the new site (WAL) rather than the old one (WT3) and and in assets and compliance - devices, the systems show as in the new site ("WAL") but without the client. I've set up site-wide push installation and put in the right accounts, but no systems show up as having clients.
When I try an individual install I can see ccmsetup running in the relevant machine's task manager and the assets and compliance - devices shows "Complete" for that machine.
However, even after a reboot the machine shows as being in the old site on its config manager control panel, and still shows as "No" client in the SCCM 2012 console.
I'd be very grateful for any help.
