How to upgrade from Exchange 2000 Standard Edition to Enterprise Edition

My company currently uses Microsoft Exchange 2000 Server Standard Edition integrated within a domain (Windows 2000 Server SP4 operating system). We would like to upgrade to Exchange 2000 Server Enterprise Edition. What steps should we take?

Guessing that you are planning to upgrade due to wanting more storage, it would be better to upgrade to Exchange Server 2003 Standard Edition and then apply Service Pack 2. That will give you a limit of 75 GB. To upgrade from Exchange 2000 to Exchange 2003 you can put the CD in and do an in-place upgrade.

To upgrade from Exchange 2000 Standard Edition to Enterprise Edition, again just put the CD in and perform an in-place upgrade.

Remember, after you upgrade from Standard Edition to Enterprise Edition, don't mount the Exchange Server databases until you've applied similar service packs to the Enterprise implementation, as compared to the service packs you applied to the Standard Edition.
