Your owa is coming in from the outside on port 80 to www.yourcompany.com/exchange<http://www.yourcompany.com/exchange>. That is mapped to a public IP address just like your MX. So same deal, you have a mapping in your pix to send that to a certain internal IP address. So when you change the IP on the exchange server that should happen the same way. Just make sure your Exchange IIS is set to answer to that URL, on the host header section of IIS.

Cool yes my exchange box sits inside my firewall and actually the nating is done on our pix so I really just have to change the ip address of the new server to match the old one after I take it offline. Is it same to change the netbios name of the new server so I don't have to mess with owa too much or should I just use a new url? Thanks! ________________________________ From: Kennedy, Jim [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 13, 2008 3:34 PM To: MS-Exchange Admin Issues Subject: RE: Just about done with migration... Just in time to migrate to Server 2008 and Exchange 2007! Just flip the IP address on the old exchange server to the new one when you are done. That is the simplest solution. I am assuming it is inside your firewall, so you have an internal IP address on them.......you could also just change the firewall/router rule that is sending port 25 to that server.....you can do this without touching your MX records or calling your ISP. It would be easier that way. From: Chyka, Robert [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 13, 2008 3:30 PM To: MS-Exchange Admin Issues Subject: Just about done with migration... Hello All, I'm just about done with a NT 4 and exchange 5.5 migration to windows server 2003 and exchange 2003. I used vmware to do the domain migration and kept the domain name the same. Exchange is still at 5.5 but is functioning under the new 2003 domain in native mode after I ran forestprep, domainprep, and configures the ADC from the exchange 2003 cd. I am bringing up a new exchange box and im going to transfer the mailboxes to the new box and decommissioning the old exchange server. It will have a new netbios name and ip address. Our external dns is hosted by our ISP and our MX record sits there. Do I need to add another mx record with a weight of 20 for the new exchange box and when the old one is ready to be removed change the new MX record to a weight of 10 with our isp pointing to the new url or am I over thinking this and no changes will have to be made?
