Does Microsoft provide an in-place upgrade solution for Exchange Server 2003 to Exchange Server 2007?

Exchange 2007 is supported only in production environments running on 64-bit (x64, no Itanium); Exchange 2003 is supported only in production environments running on 32-bit platforms. There's no direct in-place server upgrade possible. Instead, you'll need to take a swing approach, in which you'll bring a new 64-bit Exchange 2007 server into the existing Exchange organization and migrate mailboxes and services to the new server. You can migrate mailboxes by using the Move Mailbox Wizard or the Exchange Management Shell move-mailbox command. (Look for an upcoming article that explains how to use move-mailbox and other Exchange Management Shell commands in the January 2007 Exchange & Outlook Pro VIP.) You should use the Exchange 2007 functionality for mailbox migrations; you can't use the Exchange 2003/Exchange 2000 Server mailbox migration wizard to move mailboxes between Exchange 2000 or Exchange 2003 and Exchange 2007 servers. . . .
