Software Deployment

Currently running KACE SMA (Version: 13.2.182) - having some issues using WFU to push Windows 11 onto machines running Windows 10 22H2. These computers are capable of being updated, and have been updated individually through Windows Updates. They meet all the requirements set by Microsoft, and are updated to very current cumulative updates. They are also all the same model: Dell OptiPlex 3070. I have run tests with up to 41 devices, and tests with as few as three. 

The tests have been somewhat successful, but my failure rate is around 70%.

• I am running a Detect/Stage schedule, followed by a Detect/Deploy afterwards. It is not on a schedule, I am doing this as "Run Now"
• The settings of these deployments include Timeout after 8 hours (detect and deploy), run on next connection if offline, maximum deploy attempts = 10. 
• I am using both "Upgrade to Windows 11 Version 22H2 x64 Business Editions" and "Upgrade to Windows 11 Version 22H2 x64 Consumer Editions."
• The staging seems to work ok every time.
• Some of the detect/deploy results were "Completed", "Error", "Error (Agent Disconnected)", "Error (Failure to upload a results log)."
• The computers are on the domain, and were not asleep or turned off.
• Most of the computers which successfully update do it within around 3 hours. Most of the computers which fail take anywhere from 3-5 hours before failing (short of the 8 hour timeout). 

I am wondering if anyone has any large scale success with this process, and if there were any issues, how were they resolved. Also, did updating the appliance to 14.1 resolve those issues? We are planning on updating to 14.1, however we are about a month or two out from being able to implement it.
