Production Environment: Exchange 2013, Windows Server 2012; 400 users.
Our original mailbox configuration is proving problematic. We are spinning up a replacement mailbox server to replace it entirely with.
What is the best option to do this and where can I find step-by-step instructions? Is creating a DAG with new mailbox server, creating a database copy on new mailbox server, then removing old mailbox server and removing DAG the way? Or just moving mailboxes? If this is the case, do we have to re-link mailboxes? I've looked for some time before asking this question. I couldn't find anything that gave me the confidence to pull the trigger yet. This is a new Exchange setup and I don't quite trust it or myself to make the decision on my own.
