Hi there Mohd Atif Husain
Thats a good question and thanks for using QandA platform
Stopping or disabling SCCM services before performing an in-place OS upgrade is generally recommended to ensure a smooth and uninterrupted upgrade process. While SCCM itself is not directly impacted by the OS upgrade, stopping its services can prevent any potential conflicts or issues during the upgrade process.
After completing the OS upgrade you can start the SCCM services again to resume normal operations. Be sure to perform thorough testing to ensure that SCCM functions correctly on the upgraded OS before resuming production activities.
If this helps kindly accept the answer hanks much.
