Moving from Exchange 2000 to 2003

We are looking to setup a new exchange server.  I'm currently running a DC/Exchange 2000/Windows 2000 server.  What i would like to do is keep the DC on the older server and move exchange to a Windows Server 2003/Exchange 2003 machine.

Can anybody give me instructions on the proper way to do this?  I've moved exchange mailboxes before, but i'm not sure how to separate the DC and exchange and still allow them to talk to each other.  Thanks for the help.

Hi sbock,

You can setup exchange on another server and it will use LDAP to talk to the DC. As long as your DNS, WINS and GC are setup correctly everythign should just work.

Good Luck,


One thing to note. Please ensure that you patch your AD2000 directory to fix the incorrect LDAP field to prevent ending up with duplicate entries in AD. Read the MS migration documents before you attempt anything.
you need to install the windows 2003 server and join it to the domain
install exchange 2003 on that server
replicate public and system folders
move mailboxes to the new server
stop the exchange services on the old exchange server
check mail flow and everything
once confirmed that exchange is working fine, uninstall the exchange from the old box
