Hi,

 

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 : 
https://docs.microsoft.com/en-us/Exchange/plan-and-deploy/supportability-matrix?view=exchserver-2019...

 

But somebody confirmed it on the last post here : 
https://techcommunity.microsoft.com/t5/windows-server-for-it-pro/exchange-server-2010-amp-windows-se...

 

I prefer to be 100% sure before remove the last Windows 2012 R2 DC :) 

 

All informations are welcome, 

Thanks!

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
