Exchange 2010 post migration

Hello,

abc is my old 2003 exchange server

def is the new 2010 exchange server

Moving mailboxes completed but now OWA does not work. I'm assuming it's because DNS still point to abc when looking for OWA.

So I know I can change the IP of def to abc but can I rename the server also?

If you just change the port forwarding on your router to DEF's internal IP then the OWA should start working.  

However Exchange 2010 it won't be using the /Exchange virtual directory anymore but /owa so you would need to setup page redirection on DEF to ensure the /Exchange redirects to the new /owa

Thanks DLeaver,

I figured once I change the internal IP to the old abc server it should work. I guess my question should be can I change the server name from def to abc? outlook clients are setup looking for abc.domain.local.

If you have moved the mailboxes then your clients should now be pointing to def

Changing the server name and IP of def to abc on your internal network is going to cause you a number of issues.

Can you describe your setup a bit, DC's, migration plan used....

I should have said the "test" mailboxes are moved.
2 2003 dc
I used the transition guide by milind Naphade.
I am in the process of syncing the public folders before they are moved.

If I don't change the IP then I have to change the MX record to point to the new server IP. I would then have to go to every client that has outlook and change what mail server it is looking at.

If you are using Outlook 2007 onwards then the clients will auto repoint themselves to the new Exchange.

In Exchange 2003 renaming he Exchange server would break it, you have to consider all of the DS and IIS functionality and this hasn't changed much in Exchange 2010.  So in short I wouldn't try it.

Changing your external MX isn't necessary as the port forwarding explained above would change that.  Changing any internal MX would be a minor step in comparison.

Right now I'm using NAT and not port forwarding.  I figured if I change the IP then all should be ok. Am I thinking correctly?

Why spend so long doing email signature updates?

Do you spend loads of your time carrying out email signature updates? Not very interesting are they? Don’t let signature updates get you down. Let Exclaimer Cloud - Signatures for Office 365 make managing email signatures a breeze.

Same thing, at the moment do you have a rule which points external traffic on port 25 through to the abc server?  Change this to the def server on the internal network.  You will need to setup your receive connector on the Exchange 2010 if you haven't already

If you tell me what router/firewall device you are using that would be useful

We have a Sonicwall 240 NSA. But all mail is going through MXToolbox and I have the settings for that. I just can't change directories to program files in EMS.

I do a "cd  Program files " and get:

So in the SonicWALL you will have the Firewall option on the left , from here there will likely be a WAN to LAN rule that is sending SMTP traffic to the abc server -and ideally a LAN to WAN rule that only allows SMTP out from the abc server......
