I have a few questions on an upgrade I will be working on. We will be going from NT4.0 w/5.5 on a PDC to 2003. So, I have the server/AD side under control, but need a litle info on the exchange side. (I have not worked with 5.5, only 2000 and 2003 exchange servers, hence the worry). I am assuming that the 5.5 server is configured with Internet Mail Connector since the business now gets external email. They have a second 5.5 server in another city the receives email from the primary server, but is able to send on it's own. I will have the second server on site for the upgrade. My questions:
1. When I bring up the new 2003 exchange server, can I re-number the IP on the 5.5 box and use it's old IP on the new exchange server so I do not have to assign new MX records?
2. I don't think I will have to configure the virtual SMTP connector on the new server, it should send and receive on its own should it not?
3. If I have two exchange servers in different locations (2003), how would I configure the secondary server, the one in the other site, to send email if the link between the sites is down? We have a point to point between the two, but both sites have their own internet connections . Does it need its own set of MX and A records for this? I thought exchange in a multi server environment was pretty hands off. I am planning to install exchange on a DC for this site, they only have 1 server. After the install, change IPs to the orginal NT 4.0/5.5 server fo this site and ship it out. Any problems with this?
Thanks - Wayne
