Managing and deploying updates via Configuration Manager
Hi,
Thank you for posting in Microsoft Q&A forum.
Yes, Configuration Manager supports the in-place upgrade of the server OS that hosts a site server and any site system role from Windows Server 2012 R2 to Windows Server 2019. As long as you follow the documentation it should go well. Please refer to:
Upgrade on-premises infrastructure that supports Configuration Manager
Thanks for your time. Have a nice day!
Best regards,
Simon
