You'll have to use the MS tool for it. That is the only way to migrate. I have heard good and bad stories about it.
Editor's note:
The tool is called the Exchange 2000 Migration Wizard and comes with the Exchange 2000 Service Pack CDs. See the following Microsoft articles to get a grip on the Wizard:
- Introduction to the Enhanced Migration Wizard
- Using the Exchange Migration Wizard to migrate mailboxes from an Exchange organization
