Hello
Thank you for your question and reaching out. I can understand you are having issues related to SCCM client upgrade.
Please try to use "Automatic Client Upgrade” option from Hierarchy Settings.
The Upgrade Client Automatically when new client updates are available is the best option I can suggest.
This process is improved a lot with the latest version of SCCM. This is a good method when you want to upgrade all the clients on a particular site.
