In a plan to migrate our network to AD I need to migrate user mail data on an Exchange box in Domain1 to Domain2 which will be W2K AD. Is it possible to bring up a seperate Exchange server in the new domain, recreate users with the same usernames (passwords are not important) and then copy the user mail from the Domain1 Exchange server to the second Domain2 Exchange server? If not, how would you suggest I move mail data from the original domain to the new domain? The only restrictions are that usernames have to be the same but passwords don't. All client workstations will be manually added to the new domain. I know I can use addusers.exe to bulk migrate the use accounts but I'm not sure about exchange mail.

This one is pretty easy, install M$ exchange 5.5 on your new server in domain2. when installing make the new server be part of your existing exchange organization. Then in excahneg adminisrator choose the server in domain1, select all the mailboxes (except servrice account mailboxes) then choose move mailboxes from the middle menu (sorry im at home w/o an exchange server to chek exactly which menu it is)and choose the server you want it to move to. This will take awhile. Then you will have to go through and setup the primary account for each user to mathc the users in domain2. Unless of course you have already migrated the user accounts. ope this helps! ---jas

There are basically three methods: move users via Exchange Administrator, use the Move Server Wizard or do a "forklift migration".

Personally, I like the forklift migration because you can keep the original server up and running until you get everything tested on the new server - then just swap network cables and it's a done deal with the added security of the old server still intact if anything goes haywire.

Details on the forklift procedure can be found on TechNet at Q199954.

Incidentally, all these procedures are based on the servers being in the same Organization and Site.

In order to do that we created a site connector, the administrator from both domains has to be added to the other org,site and server. (Make sure administrator for the new site has rights permissions before you disconnect). Move the mailboxes fromone server to the other. Disconnect site connector when done.

Forgot to add that you'll need to create a two way trust relationship between the two domains also. Good Luck.
