This blog post covers how to automatically update sccm client versions using the Automatic Client Upgrade feature in the SCCM hierarchy settings.
How to automatically update clients using automatic client upgrade
This is how you enable Automatic Client Upgrade:
1. Select your Site and select Hierarchy Settings in the top ribbon.
2. Go to the Automatic Client Upgrade tab
3. Check Upgrade client automatically when new client updates are available and press OK in the window that pop-ups
When enabling the Automatic Client Upgrade, SCCM will create a Scheduled Task for each client machine that has a version number lower than the Latest Version property. The Scheduled Task will be created with a random run interval, which means that all of the clients will not be updated at the same time, which could cause performance issues. Define during which interval the clients will be upgraded.
7 days is the default, which is usually fine, but change it according to your requirements.
If you go to the tab Automatic Client Upgrade you see what version all clients will upgrade to.
I always recommend using the Automatic Client Upgrade feature.
