Exporting \ Importing Active Directory

I am replacing my old mailserver (server 2003 enterprise \ exchange 2004 ) with a new computer and i am trying to figure out how to export all of the users and import them into the new mail server. Is is even possible? All i really need is just the info that makes up the email accounts. Any ideas?

Thanks

 

If these are two different servers, have the new server join your active directory and exchange organization. Then use the move mailbox wizard to move your mail over to the new server.
Unless of course these are SBS server, in which case, this is not an option. You could also perform an ldif output of the ldap directory within active directory, and import that file into your server. Microsoft has some good kb articles that describe how to do this using the resource kit.
