Migrating from Exchange 5.5 to Exchange 2000

I am doing a migration this weekend. (I'm being forced into completing it by June 30, otherwise I'd take more time to read and prepare.)

Current setup:

4x Win2k DCs running Active Directory
1x WinNT4 running Exchange 5.5 SP4

I have only one Exchange server in one Exchange organization (thus only one site), and one AD domain (%company%.com). All users have accounts in AD which are currently used as authentication for their mailboxes. All users are mail-enabled.

I've already created Universal Distribution Groups that mirror Exchange Distribution Lists.

My plan, based on what I've been able to read thus far is:

*Install Exchange 2k into the same Exchange Organization/Site
*Move the mailboxes from the Exchange 5.5 server to the Exchange 2k server

Still need to figure out how to move the Public Folders, but I've only got a couple of those.

This seem reasonable? Or am I missing a pitfall I should be prepared for?

Yes very reasonable, in regard to the public folders, you can do it in 2 ways,

1. export them to a pst file from outlook client, then create the new PF and import the items back into it

2. create a public folder instance on the new exchange server

Rehome the folders to the new system....just replicate and then when your in your 5.5 tell the folders that you want to rehome them...

migration is a piece of cake.

Had trouble doing this in my lab.

I installed Exchange 5.5 SP4 on a member server (Win2k).

I was able to install/run ADC without any problem. Replication was working fine.

I ran /forestprep and specified that I wished to join the existing 5.5 site.
I ran /domainprep. Schema elements were in place (e.g. I could see Exchange info from AD Users and Computers).

I installed Exchange 2000 on the DC (only DC in the domain). But when I tried to move mailboxes (from Exchange 5.5 Administrator) I'd get an error (and now I forget what it said) which advised me to restart both machines and try again. I did, to no avail.

I slapped base images back on both boxes to start from scratch. This time I am going to install Exchange 2000 in a separate site and use Migration Wizard to move the mailboxes.

Wron way o move them...you move the mailboxes thriough the AD user and pcs portion under the Exchange settings in E2k

pcbrat

Dont got the long way...when you move int the same org its a piece of cake... you had it up to the move part... You need to laucnch Excnahe Ad user and computers and go to Exchange tasks and then move mailbox...its a wizard....

try it again you'll see....

You're killing me here... :)

After that, can I raise the Exchange organization to Native and be done with the 5.5 box?
