Exchange 2010 - change internal address records

Hey Guys

I have an Exchange 2010 server which is using "mail.domain.com" as the internal address record for "OWA, ActiveSync default web site, OAB default web site,Pop3 & IMAP, ECP, CLIENT Receive Connector and the SSL certificate"etc.

The client would like the address changed to mail.newdomain.com.

If I change the addresses for OWA, ActiveSync default web site, OAB default web site,Pop3 & IMAP, ECP, CLIENT Receive Connector and purchase a new SSL certificate and apply it, is there anything else I need to worry about? They have a couple of LOB applications that are also linked to Exchange and a 3CX server.

Has anyone done this before?
Also if I make the changes, will it break the clients Outlook 2007/10, iPhone Activesync profiles and the LOB apps? Will I need to re-add them?

Am I best of leaving it as is and making the changes when I build them a new network next year? What do you guys think?

Kind Regards
Aaron

First of you have to find what all apps using your current name.
Do you have DAG/CAS Array configured?

You could use a trick to test it. I think but you will be safe till you make sure all users/apps using the new name.
Assign an extra IP to the exchange server NIC and add A record points to this new IP in your DNS server if not created automatic.

Hey abbasiftt

Haven't got DAG/CAS array in place.

Have you used the above method before? How did it go?

If CAS array is not configured it is easy.
I tried this for OWA not for all but it was pointing to the same IP and it was successful.
Removed the old name from cert and OWA config

That will work as it is pointing to the same server.

once everything working remove the IP added to the NIC

ahh so if I add an extra IP to the exchange nic, I can slowly migrate users to the new address and then change what IP the A record points to at a later date?
what happens with the exchange certificate. can I run 2x certs at the same time for all the services that are currently in use?

Later if all are working fine delete the old name from DNS server and keep only one IP for the new name and autodiscover.


-->what happens with the exchange certificate. can I run 2x certs at the same time for all the services that are currently in use?

yes you can but you cannot enable same services on 2 certs.
