One of our customer need to migrate all these DC Windows 2012 R2 to Windows 2019.
Somebody have experience with Exchange 2010 CU30 (multiple DAG servers) during a migration of Windows 2012 R2 DC to Windows 2019 DC on the same domain ? It is working ?
I know for the forest level 2016 but for the DC?
It's not supported on the current Microsoft Matrix :
But somebody confirmed it on the last post here :
I prefer to be 100% sure before remove the last Windows 2012 R2 DC :)
All informations are welcome,
