When migrating cc:Mail DB8 post offices to Microsoft Exchange Server using the Migration Wizard, you should update the Migration Wizard .dll from the version on the Microsoft Exchange Server compact disc to a newer version. The new version provides fidelity enhancements for migrating messages and attachments from existing cc:Mail DB8 post offices. The updated Migration Wizard is available from the Microsoft Exchange Server Migration Web site (http://www.microsoft.com/exchange/migrate).
