Two Exchange servers, one domain
Posted on 2013-05-16
We have used a single Exchange 2010 server on our hosting domain for some years. Now we like to add a new Exchange server to the same domain. The reasons for this is that the existing server is installed on a domain controller and got limited amount of disk space.
The second reason is that we want to use a new server certificate and IP address for internet access when we create new mailboxes for new customers.
If it’s possible, we want to use both Exchange servers at the same time with different stores and gateway and move all stores to the new server later. In the end the existing server only will be a domain server. Is there any issues with this setup? I suppose this is the same scenario as when you migrate from 2003 to 2010. The different is that both servers will communicate out on the internet and not only forward mail from one server to the other.
