I am about to finish the process of moving to exchange 2010 from 2003.

I have 2003 up and running with the rest of the users mailbox. I have 2010 up with a few test mailbox and mine as well.

I'm ready for switch over, I have these steps left:
It is going to take the old public ip address. I made these changes one night, but it did not take affect. Is there something I might be missing?

7.      Change watchguard policy: SMTP-PROXY incoming to reflect new server 1.1.1.1
Was 1.1.1.5
8.      Change internal dns records
a.      Mail cname record, change target host to newexchange.com, previously oldexchange.com
b.      Webmail cname record, change target host to newexchange.com, previously oldexchange.com
Change watchguard policy: http-proxy-inbound incoming to reflect new server 66.66.66.66
9.      > 1.1.1.1
Change watchguard policy: terminal services- incoming to reflect new server 66.66.66.66
10.      > 1.1.1.1
Change watchguard policy: https-inbound incoming to reflect new server 66.66.66.66
11.      > 1.1.1.1
Change watchguard policy: pop3-proxy incoming to reflect new server 66.66.66.66
12.      > 1.1.1.1

i did follow that guide, but that part about switching the feed over was vague.

I'm not sure if I'm missing something.

The guide is very clear but if you have problems here it is using other words:


Go to your DNS and change anything that is pointing to old.exchange.server (192.168.1.20) to new.exchange.server (192.168.122)... CNAME, MX, Host, etc...

Then, go to your router/firewall and for every rule (NAT/Port forwarding/policy) pointing to 192.168.1.20 replace it with 192.168.1.22.

If mail doesn't flow as expected go back to the guide and follow Step 4.6 to fix it.
