I have plans to upgrade my SCCM 2012 R2 SP1 site server O/S from server 2008 R2 to server 2012 R2. My question is related to windows updates that have already been deployed to my workstations cache and are waiting for their installation deadline to occur before they are installed.
If my site server is not available during the installation deadline will that prevent the workstations from installing their windows updates from their cache folder?
