Upgrading a 5.5 to 2003 exchange server.

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

    Accepted Solution

    Exchange 5.5 use IMC to send and receive mails to internet. For mail between exchange servers MTA is used. In any Exchange 5.5 server environment only one IMC is used. If multiple then costing is enabled.

    1. Yes

    2. Yes

    Thanks for the info.  
    1. On the second server that I am shipping out, will be running on a DC, I should configure different port for the ADC when I connect it to the 5.5 for mailbox transfer?
    2.  What is the default port 5.5 uses?

    The default port used is 389
    change it to 390 as the dc will use 389 and block it for its LDAP operations.
