SEPM update 11.6->12.1 caused managed clients to remove all components in 11.6

This issue has been solved. See solution.

Yesterday i initiated the upgrade of my SEPM to 12.1, i planned to update just the manager and my server-group and wait with the clients until i was certain everything worked fine.

However somewhere along the way all clients removed their components (antivirus, network protection etc). SEP 11.6 was still installed and showing a systray icon on all of them, there just weren't any active components inside SEP.

Does anyone know what might have happened and how i can make sure it doesn't happen again?

My SEPM is on a Server 2008 x64, clients were running XP, Vista and Win7 (both 32 and 64bit).

I have two groups, Servers and Clients, with separate policys in each. Since i didn't add any 12.1 packages to the client-group i didn't think anything were going to be changed there.

(also a rather disturbing thing is that windows 7 claim that there is no antivirus or firewall installed on the machines after an upgrade)

Hello,

Could you upload some screenshots on what happened??

When you say, "there just weren't any active components inside SEP", what does that mean??
