Exchange 5.5 to 2003 Mailbox migration problem

Posted on 2007-07-31
Last Modified: 2010-03-06
I am installing Exchange Server 2003 on a new Windows 2000 server. The idea is to migrate my Exchange 5.5 mailboxes from the old mail server, which is also a Windows 2000 server,  to the new server. When I try to do this using the Migration wizard, I get a message that the server, password or port is wrong. When I use the active directory tool in the deployment tools, it says the source server is not an Exchange 5.5 server. I have tried everything I have read on this site, including changing the LDAP port the 5.5 server uses. Any help or suggestions would be greatly appreciated.

    Exmerge the old mailboxes from 5.5 and exmerge them into 2003. if the alias name is unchanged this works great. If not, you need to modify the name of the PST files. if the legacyexchangeDN is changing, you need to copy it from the 5.5 accounts, then add it to the 2003 accounts as an X.500 address.

    This is a lot of work!

    It is a lot of work, but proved to be an effective workaround.

    Blame it on Bill! I just finished a 5900 user migration from 5.5 to 2k3. Due to policies at company, thats how I had to do it. Copious amounts of scripting helped, but it was still a ton of work.
