1) There are Exchange 2003 in 2 domains; Boba and DingDong Domain
2) I want to migrate to Exchange 2007
3) There are suggestion (from the Experts from EE) that i have to move the Mailbox and also move the user
4) I am confused (related to this); per my understanding the Users are at Active Directory and Nothing to do with the Microsoft Exchange
5) Per my experience of moving exchange 2003 to exchange 2007 (only one domain); i do NOT need to move the User
6) Would experts explain why i have to move the users (if it is more than one domain)?
7) Thank you
