SUMMARY
Microsoft provides three tools to facilitate migration to and from Exchange Server version 5.5 and Microsoft Exchange 2000 Server: the Move Server Wizard, Exmerge, and the Exchange Migration Wizard (for Messaging Application Programming Interface [MAPI] migration). This article describes different considerations for each of these tools.
