Transition from Exchange 2003 to Exchange 2010

I have just started the process of migrating from exchange 2003 to 2010. I have checked that I have met all prerequisites using the Pre-Deployment Analyzer tool and started the installation of the CAS role. Upon completion of this, the first message/error I recieve is: “Setup is going to prepare the organization for Exchange 2010 by using ‘Setup /PrepareAD’. No Exchange 2007 server roles have been detected in this topology. After this operation, you will not be able to install any Exchange 2007 server roles.”

1. What will this do to my existing mail server if anything?
2. Will this cause any problems or disruption in service?
3. Will they coexist separatly or be working together after I begin the installation?
4. Can I continue installing all roles for Exchange 2010 without loss of service to my exchange 2003 till I move the mailboxes and change my internal firewall rules?

1. No, this is just a warning that you cannot use 2007 servers, you can ignore this since you are going to 2010.
2. No disruption at all.
3. They will exist as separate servers but will work together.
4. Yes, the server will see the 2003 box and add all of the mailboxes as "legacy mailboxes" but that will not affect your current environment. No effect on mailflow until to make necessary changes.

Thanks

Can you elaborate on #3 a little more? You say they will work together. Will any mail actually be going through it before the complete transition? For example, if I enter a setting incorrectly or have to shutdown the server for maintenance for a day will it effect anything? Will the external access or OWA be affected?
