I have WSUS running on a ConfigMgr server, and ConfigMgr is currently patching clients and servers through ADR's. We're in the process of removing our servers from ConfigMgr management due to costs, clients will remain within ConfigMgr.
My question is, can I use the existing WSUS feature to patch the servers via GPO's? I ask because with ConfigMgr, you basically install WSUS and then don't touch it again. All patch management is done within ConfigMgr. I'm concerned that approving updates within WSUS might start to break things for ConfigMgr.
