I'm in the process of migrating our exchange server to new hardware.
We currently have Exchange server 2003 on a Win2k Domain Controller.

Does anyone have detailed steps on how I could bring up a new server
with the same name as the old one and then restore all the mail boxes and public folders.

I've since found out that this is not recommended by MS, and that it will be harder to restore the data.

I thank you in advance.

Hello Jay,
 
Here is what you are looking for.
How to move Exchange 2003 to new hardware and keep the same server name
http://support.microsoft.com/kb/822945
The only difference between your requirement and this MS article is that you have Exchange installed on Domain controller
 
Exchange is NOT recommended to be on DC so the best way is to add another DC in your domain and then follow the steps mentioned in article (822945)
 
Feel free to reply back if you have more questions, I know exactly what you are looking for!
 
Good Luck,
Sanjay.

I thank you Sanjay for your quick reply.
 
I think you're right about not putting the New Exchange server on a Domain Controller again.
What steps would I have to take then ?
 
1. Create a new member server = called server2
 
2. Install exchange / hotfixes
 
how do I mover/replicate all of the mailboxes and public folders
What about the external connectors that were setup
At what point do I take the original exchange server down ? (server1 - which is also a DC)
How do I then point the clients to the new server (server2)
Can I keep the old server around and not make any changes as a fall back position.
 
I can't seem to find this in techcnet, can anyone point me to the right article.
Any help would be appreciated.
Jay

When a mailbox is moved from server1 to server2, you will need both servers still online so that users can log on. When a user logs on, his outlook profile will automatically be pointed to the new server.

Is there any specific reason of keeping the same name?
 
Alternate available to your problem.
If you add additional server in same Administrative group and move all resources to new server, your outlook clients will be automatically redirected to use new server.
 
In this situation although your server name will change but you can easily move all resources with zero% downtime.
 
Use this article to move resources
How to remove the first Exchange Server 2003 computer from the administrative group
http://support.microsoft.com/default.aspx?scid=kb;en-us;822931
 
 
If you still think you need same server name then you might have to add another DC in same domain so that config information is shared and you can demote DC having Exchange server and then bring another member server and run disaster recovery switch to install exchange with same server name.
 
Hope I am not confusing you. J
Sanjay

I thank you all for your help.

We initially thought it would be easier to use the same name, but based on your recommendations:
It looks like we should be setting up a member server migrating away from the DC.

I think I'll try this in a test environment to see how this is going to pan out.

Have a great day.
Jay

Thats is correct Jay, swaping hardware and keeping same server for Exchange on DC is really a royal pain but trust me adding another server is very simple with zero downtime.

Please feel free to reply if you have any questions, if you want we can fix some time and try this in lab using virtual machines.

Good Luck!
Sanjay.

Im on the same path. added additional exchange to the same organisation and I'm able to move data over to the new exchange without any problem. But once mailbox is moved over, user is unable to send or receive the email - Outlook did pickup the new server.
Original server is running on the 2k3 DC, both servers are on the same SP level (1), able to see one another - located on the same subnet.
The old exchange has email filter (mailmarshall) on the same box, as well as ISA in caching mode only.

Thanks for any suggestions.

Regards,
Trbonja

Are users able to send/receive email between each other on the new server?
Are users able to send/receive email between the 2 servers?

Ok we have narrowed it down a bit. Do the users get NDR when they send emails between servers?

OLDSERVER 2 NEWSERVER --> yes/no
NEWSERVER 2 OLDSERVER --> yes/no

I assume mail from oldserver 2 new server may work but not the otherway, but please confirm for me. Any AV on the new server?

Thanks for reply
OLDSERVER 2 NEWSERVER --> NO
NEWSERVER 2 OLDSERVER --> NO
User's on each server get NDR and there is no AV on the new server. On the old one AV doesn't scan the exchange folders.


Thank you again,
trbonja

from oldserver, telnet to the newserver to port 25. type EHLO.
Do the same the other way round and see what happens. What is the NDR users get on both sides?

I've been down this road :). Old server 25 calls are intercepted by the email filter software (mail marshall) and the new server has an reply from exchange.
NDR received by the test user is "timed out"

Thank you for your assistance.
