Migration of Windows 2012 R2 DC to Windows 2019 with Exchange 2010 CU 30

Occasional Contributor



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,

I will advise you to stick to Microsoft recommendation, maybe something after running it for a while will misbehave and you will send days troubleshooting it.

or at least if you can convince you the customer to upgrade to exchange 2016 will be better
