We have DAG environment Exchange 2010. We have two Edge Servers. 1 is located at a DC with all of the other Exchange equipment. The other edge server is located at a remote office location that we are closing. We will be removing this edge server and relocating to the main DC. What affects will the shutdown and changing of IP address for this Edge server have on the Exchange environment? Do I need to do some sort of fail over from this Edge server to the other one currently at my DC?
