Failover in such a scenario is likely a bit more complicated than simply tossing out a new host entry or two. What are you using now to specify the target server in your x.400 connections? Are users going to be testing this failover too by connecting to the alternate Exchange server? The failover steps required could be further complicated by your underlying network routing topology. Your IMC represents a critical SPOF, what's the plan for providing redundancy there? With a single hub, what happens when the hub site is the one effected by a disaster? All 16 sites now become islands until the restoration SLA is met for that hub site. The best way to find out what is going to be required to really pull this off is to test it (lots)... Either in a lab or with a non production organization on your production network.

We want to propose a solution to have replace any of the sites in case of disaster in the area where the site is (consider that the server is lost). We should use just the tape backups from the site, we can build a similar server in a remote location, same name and in same domain. Our question is how can we do rehearsal of this proposal? Should we remove the existent and operational site and replace it with our restored-server (send receive some messages)? Are we going to introduce host entries at that moment? Then we need to switch back to the original server..does anybody have this reharse before?
