Switch the IP address in DNS - not on the servers. And only for the CAS functions; everything else is handled by Exchange automagically.

You need DAG for MB role, HT automatically does failover HA/FT, and a RPC Client Access Array on the CAS. The only challenge is that for true HA/FT, you'd need to load balance the CAS. If you don't load-balance CAS then you'll need to have a DNS entry for the FQDN of the RPC CAA with a low TTL and in the case of an extended failure, switch the IP address. (I teach a full day class on this, and that's not long enough to cover all of the various details, but those are the basics of the class in 3 sentences.) Regards, Michael B.

One of the features that excited me about Exchange 2010 was the ability to have database replication between two servers. My question - is it possible to have database replication and failover between the two servers if all the roles are on the two individual servers? I am not talking about high availability. I understood that there could be replication between two servers and if one of the two failed the other would take over. The difference is that with high availability the change would take minutes and with the other it could take 20-30 minutes.
