Our Exchange setup - we have an Exchange 2003 partially migrated over to Exchange 2010. The 2003 Exchange / server is and our 2010 Exchange is

We have various in house websites that has contact forms also emails out reply's etc.


In the coding of the websites in many many places the SMTP is pointing to and using our old Exchange Server but we will need to complete the migration and shutdown Exchange 2003. I believe this will stop many websites from emailing out. Is there a way of adding the to the new Exchange or a way so when Exchange 2003 gets shutdown the websites will still be able to SMTP to

Why not just change the website code to use and use that for anything which needs an email server? I set that up to point to before I left :-) When you move to the next version of Exchange, just change that CNAME to the new Exchange server and you'll not have to change the website code (or anything else) again. – Ben Pilbrow Oct 16 '12 at 12:45
Hiya, I did try to explain to the programmers that they should have used a generic name that could be used, but a certain somebody would have to modify lots of code as the is hard coded everywhere. – Matt Oct 16 '12 at 16:26

When you're ready to turn off the Exchange 2003 server create a CNAME record in your DNS zone for "exchange" that points to the A record for "SVER03".
