What kind of issue do you have?

Do you need to manage database availability group membership? Here is link https://technet.microsoft.com/en-us/library/Dd351278(v=exchg.141).aspx

This forum is for Exchange development questions. Your question seems more like an administration question, so I will move it to the Exchange administration forum on TechNet.

Hi biplob9s,

Thank you for your question. 

It's supported to create a DAG that contains a combination of physical Mailbox servers and virtualized Mailbox servers, we could refer to the following link:

If there are any questions regarding this issue, please be free to let me know.

Best Regard,
