I am currently working with a new implementation of Exchange 2007 that is still in the testing phase. It consists of 2 Edge Transport servers and 2 Mailbox/Hub Transport servers. We will have approx 1000 users accessing this mail system and it was suggested that we break out the Hub/Cas portion from the Mailboxes and place on separate servers, which we did. We setup the servers but have not yet installed the Hub/Cas applications. My question is, does anyone have any documentation that specifically speaks on, (and in depth), connecting the Edge Transport to the Hub Transport to the Mailboxes as well as load balancing the three. I have 2 Edge Transport, 2 Hub Transport/Cas and 2 Mailbox Servers on a Blade Center. The Edge Transport servers are in the DMZ. The Hub Transport/Cas and Mailbox servers are inside the network firewall.
Also, I have already added mailboxes to the Mailbox/Hub Transport server prior to breaking out the Hub/Cas portion to it's own server. Will uninstalling the Hub/Cas portion from the Mailbox server hinder the currently added mailboxes at all?...and if not... is there a way to copy those mailboxs that I have already added from one Mailbox server to another redundant server without recreating?
I am a Network Admin, but first time installing and implementing Exchange. (Can you tell?) Thanx in advance for any input.
