Sccm primary and secondary site sever inplace upgrade from 2012 R2 to 2019
What is the best practice?
We are going to plan in-place upgrade of sccm primary and secondary site servers from 2012 R2 to 2019.
Does the primary site server need to be upgraded first, or should the secondary servers
Also, do we need to stop the sms and sql services before performing inplace upgrade
