i have just one exchange server on premise; an exchange 2010 server. I want to replicate this server for redundancy. Please how can i go about it. I have a Hyper V with Virtual machines sitting in my domain as well. How can i replicate it on the virtual machine and load balance between them. Is that possible. Can i move it to another branch office location that i have a VPN site-to-site connection for disaster recovery? I would appreciate any good documentation on this . How does DAG play here?
