Upgrade/ Migrate Exchange

By ratherbfishing ·
I will soon be upgrading our NT network to WIN2K. We are still running Exchange 4.0. I am planning to Install BackOffice 2000 on a new server with Exchange 2000.

I am looking for ,tips, help, information on migrating the Excahnge users and mail boxes to the new server. I have found information on upgrading Exchange 4.0 to 5.5, and Exchange 5.5 to 2000, but nothing on 4.0 to 2000. I am thinking that I may have to upgrade twice...once to 5.5 on the old server hosting Exchange 4.0, and then to 2000 on the new server. What do ya think? Any other way to do this?

Upgrade/ Migrate Exchange

I am certain that the onlyl supported upgrade path is exchange 5.5 sp3 or sp4 to win2k.

Since your system is ex 4.0 your right in saying that you would first have to upgrade to 5.5 sp3 (minimum) then continue with the ex2k upgrade.

These linksdescribe the process in detail:

XADM: Considerations When Upgrading from Exchange Server 4.0/5.0 to 5.5

Fortunately for you their is an alternative, you could build a totally new ex2k server and import all your users that have been exmerged from exchange 4.0 thus saving you all the time and effort of 2 upgrades.

The exmerge tool is available at:

detailed usage information is below:

hope it all goes well,
