Exchange 2013 (Hyper V 2012) DAG Configuration

Exchange 2013 is not yet supported on 2012 R2.

Cliff, We have already installed it (Exchange 2013 CU3) on windows 2012 r2

Hi Vijay,
As Cliff mentioned, Windows 2012 R2 is not supported for Exchange 2013.

Apart from that, If you consider to Virtualizae Exchange - Its fully supported.
You could have all the roles even on the same server provided you have allocated enough resources for that.

There are multiple areas which need special consideration while installing Exchange on a Virtual environment.

Its worth to have a look on the technet article for the requirements

Thanks Shabarinath. We have already configured Exchange 2013 CU3 on windows 2012 R2 server (VM). It is running well.  I just want to configure one more exchange server 2013 as DAG member. Is it possible to install client access role on DAG member server (new exchange) ?

Sorry, a bit new to this bit so can someone explain if this is correct?

Is Exchange 2013 not supported if installed directly on an installation of Windows Server 2012 R2 pre SP1, but if you have Windows Server 2012 R2 using Hyper-V and setup an instance VM running Exchange 2013 it is supported?

Is that correct?

Exchange 2013 will be supported on Windows Server 2012 R2 only with Sp1.

That doesn't mean that Exchange 2013 will not work. It may or may not work - however on a support standpoint, You will not be entitled for getting a support from Microsoft if not in a supported mode.


On the DAG part, you could install a second VM and configure a DAG. However, its worth to understand the points on technet article. You could also refer the best practice guidelines for Exchange 2013 Virtualization which is a document published by Microsoft.

Thanks Shabarinath. Can i install both Client Acees role and mailbox role on it ?

Yes. Thats possible.

You can have all roles on the same server in the DAG.
However if you do that then you cannot use WNLB for the CAS role, you will need to use a third party tool.

While you are seeing no problems at the moment with Exchange 2013 on Windows 2012 R2, that isn't to say you will not have problems in the future. It is also unclear whether you will be able to upgrade to Exchange 2013 SP1 on release or not.

I would build two replacement machines on to Windows 2012 in your HyperV environment and migrate to those servers and remove the one on Windows 2012 R2.

Can i use CAS role on DAG member if primary fails ?

Thanks everyone for your contributions,
