Adding a second Exchange server to domain

Hi ,

Currently we have one exchange server 2003 handling all of our email. I would like to create a new VM on a separate server to act as a scondary email server for the domain to provide fault tolerance if the other server goes down. I'm planning to install exchange 2010,

Being totally new to this, what would be the basic steps I follow to set this up? Is there a way of replicating or migrating exchange settings like when adding a new DC?

Adding a 2010 ex server to your existing 2003 ex server will not give you any fault tolerance, if the 2003 server fails you will just have a 2010 mail server with no mailboxes on it!

If you want fault tolerance you will need 2x EX 2010 servers.
Yes you can do that, also this is called co-existance.

correct - it will co-exist, but it will not give you real fault tolerance. Big diffrence between the two.
I recommend to migrate from 2003 to 2010 and then add additional 2010 and configure DAG.

Upgrade to 2010 first and then add the new server for fault tolerance. Configure DAG between them. Coexsitence will not provide you any fault tolerance.
