Exchange 2003 to 2010

Hello,

I am currently in the process of moving to Exchange 2010 from 2003. I have a single server and a single domain. My question is, I would like to install the  Exchange 2010 software and then in a couple of days actually cut over to have mail flowing though the 2010 server. I have quite of bit of mailbox data to move and will actually be doing that overnight over some time.

But I just wanted to be sure that I can install the software on the new Exchange box and not have it disrupt email flow to the 2003 server until I start to configure the 2010 roles (they would however be installed)

Thank you,

Sean

You can install the Exchange server, Mail Flow will still flow via 2003 server. When you install first 2010 server in 2003 env, it creates one default RG connector. so no need to worry, installing exchange 2010 won't cause any issue.

Thank you for your answer. I have read that guide, but my question is can I go through the install part and then stop for a few days without disrupting service? The guide goes from installing right to configuration do I have to do this all at once? Will email still flow to the exchange 2003 server unimpeded until I change the firewall to point to the 2010 server?

Thank you
