Since Microsoft started to release cumulative updates for SCCM, we had to deploy package to Client in order to keep the clients up to date. automatic client upgrade was exclusively saved for major updates (like service packs).
Microsoft recognize the need to automatic upgrade the Clients after installing cumulative update to the site server as well.
The last cumulative update (Cumulative Update 1 for System Center 2012 R2 Configuration Manager Service Pack 1 and System Center 2012 Configuration Manager Service Pack 2) that was released earlier this month, add the ability to automatically updating the clients.
When choosing to automatically update the clients, the following will happen:
- Client package will be update.
- The update will be sent to existing clients (based on Automatic Client Upgrade settings).
- New client installations (via pushmanualOSD etc.) will include the update automatically.
