Copy Exchange 5.5 configuration and mailboxes to a new server.


We have an old PC running Window NT 4.0 Server (SP6) with MS Exchange 5.5 (SP1). We want to replace this machine with a new one and keep using Windows NT 4.0 Server + Exchange 5.5. There is no problem for us to reinstall Windows NT 4.0 Server + Exchange 5.5 on the new PC, but I would like to know how if there is a simple way (or an utility) to copy Exchange configurations AND mailboxes from the old server to the new server. We don't want to reconfigure everything manually...if possible.

Shut down the Exchange services.
-Copy the dir, priv and pub.edb files to a network location. Nothing else
-Build the new server with same name, and EXACT SAME ORG AND SITE NAME. THIS WON'T WORK UNLESS YOU DO.
-Create the same drives as the old server, the directory service and the information store won't start when you're finished if you don't put them in the same path as they are now.
-Keep same level service packs on both OS and Exchange for the new server. YOU MUST use the same exchange service account as the other server, or this won't work.
-If you have the Internet mail connector installed on this server, install it on the new server with default setting. you'll see why when we're done.
-Once you are installed cleanly, stop the services.
-Rename the mdbdata and dsadata folders, to like "dsadata.old" Just something.
-Create new blank folders to replace them.
-Copy the the database files into their respective folders.
Start the services in this order:

The IS will fail with a 1011 error. Normal. Go to the command prompt, switch to the \exchsrvr\bin dir, and type "isinteg -patch", without the quotes.
Start the IS again, it should work. Start the rest of your services, and go eat :).

On a different note, you REALLY NEED to move to service pack 4 for Exchange afterwards, you're running on code that is about 7 years old, and has a lot of holes.

I forgot to mention that the old server is also a PDC. Will it work if, before I install Exchange:

- I promote the new PC to PDC
- Demote the old PC to BDC
- than follow the steps you mentionned above.

David WilhoitSenior Consultant, ExchangeCommented:
Nope. Essentially, you're rebuilding everything from scratch. If you have good backups, you can backup the current environment and restore it to the new server, if you want to do it that way. Otherwise, you're looking at a fresh install of NT4, making it a BDC, then promoting the new one and demoting the other server. Install Exchange into the current site you have, apply the service pack for exchange, then follow the articles on removing the first exchange server in the site from MS.
