I currently prepare some compatibility and migration guides for a customer who wants to upgrade his infrastructur to Windows Server 2012 R2.
I was a bit depressed when I saw that there is a very raw support for Microsoft Exchange with Windows Server 2012 R2. The means Windows Server 2012 R2 as host, as well as Active Directory Version.
Currently only Exchange Server 2013 supports Windows Server 2012 R2 as host and with Windows Server 2012 R2 Shema (Shema Version 69).

This reference architecture is intended for customers interested in deploying a virtualized Unified Communication and Collaboration (UC&C) solution on Dell PowerEdge VRTX with Microsoft Windows Server 2012 Hyper-V. This reference architecture provides a high level design and implementation scenario for 500 users with Microsoft Exchange, Lync and SharePoint Server 2013 in a single VRTX chassis.
The Dell PowerEdge VRTX shared infrastructure platform resolves the complexities managing IT infrastructure due to hardware sprawl and proliferation of various system management tools by combining servers, storage and networking into an easy-to-deploy chassis.
A Microsoft Unified Communication and Collaboration (UC&C) solution enabled by Microsoft Exchange, Lync and SharePoint Servers provides organizations with mission-critical productivity tools—such as email, instant messaging, document sharing and web conferencing—to accomplish daily tasks. It is important to configure, deploy and maintain the applications for daily functioning. Architectural changes and feature enhancements in Exchange Server 2013, Lync Server 2013 and SharePoint Server 2013 enable better integration between the three applications and further improve end-user productivity.
Implementing the three applications together on a shared virtualized infrastructure results in greater consolidation and efficiency than implementing each application on dedicated hardware. The study in this technical guide describes the reference architecture for Microsoft UC&C solution leveraging the pre-engineered PowerEdge VRTX with Hyper-V reference architecture. This reference architecture has been used as the underlying platform to build a virtualized Microsoft UC&C solution. Certain percentages of PowerEdge VRTX resources are reserved for the solution while the remaining resources can be leveraged for running additional applications that are at the administrator’s discretion.
This reference architecture provides the design considerations for implementing the three applications on Dell PowerEdge VRTX and describes the observations from the verification of infrastructure and application performance.
