  • Hi,

    >>1. Can DAG contain different version of Exchange? Like A dag with 3 exchange 2013 and 4 exchange 2016?

    No. DAG can only have exchange servers of the same version.

    >>2. Can DAG contain mix of virtual and Physical servers?

    Yes. As long as the servers meet the the Exchange Server system requirements and Requirements for hardware virtualization.

    >>3. Can DAG contain mix of different os platform?

    No. Servers in DAG must run the same os.

    For more information,please refer to the following documents:

    In addition,please note that previous Exchange forums on TechNet have been migrated to a new home on Microsoft Q&A and this forum is for Exchange Server Development only.

    It is highly recommended to ask your question there so that there is more chance to get helpful suggestions or answers.
