Hello,

(I apologize if this gets posted to the wrong forum)

I'm doing an Exchange2007-2010 transition. I just did a typical installation of Exchange2010 (after completing all prerequisites) and I'm just starting to check/compare all configurations before installing a SAN Certificate and switching our DNS. One thing that concerns me is that I thought I would see a blank "Send Connector", but what I see is the same connector from the Exchange2007 Hub Transport (this connector routes mail through a smart host) that apparently got pulled in from the installation. When I change our DNS internally/externally to point to the Exchange2010 server, do I need to add the Exchange2010 server as the "Source Server" (From the send connector properties==>Source Server tab) and remove the Exchange2007 from the source server list?  I guess at what point will this connector know to change to the Exchange2010 server?  Or do I simply add a 2nd Send Connector and after I switch DNS I would disable the Exchange2007 connector?

- I'm a little nervous that when I change DNS this will go bad.  Any thoughts or suggestions would be appreciated.

Thanks,

Bob

Hello,

If there is a edge transport server, you will need to create a new edge subscription between the exchange 2007 edge server and the exchange 2010 hub transport server.

Later on, a new exchange 2010 edge server can be installed in the DMZ, and an edge synchronization between that exchange 2010 edge server and the exchange 2010 Hub server can be created. When this is accomplished, the mail flow from the firewall can be redirected to the new exchange 2010 edge server, and the old exchange 2007 edge server can be removed.

If there is no a edge transport server, you need to add the exchange server 2010 as the "source server" when you change the DNS record. If you can make sure all mailbox have been migrated to exchange 2010, you can delete exchange 2007 send connector.

Thanks Cara for confirming this for me. I created a send connector for the exchange 2010 server and disabled this. When I change the DNS I will disable the exchange2007 connector. The send connector will also route through our smart host (barracuda spam server). We don't have an edge transport server. So, it sounds like mail should route properly after doing the following (please confirm) (1) change DNS internally and externally (2) disable exchange2007 send connector (3) enable exchange 2010 send connector - correct? Thanks, Bob
