• BlackBerry® Enterprise Server
• Microsoft® Exchange

Migrating Microsoft Exchange mailboxes from a Microsoft Exchange version 5.5, 2000, and 2003 organization to another Microsoft Exchange organization, while maintaining BlackBerry Enterprise Server information does not work.

Currently there is no known utility or method that will retain BlackBerry Enterprise Server information in this scenario. The BlackBerry Enterprise Server service account mailbox stores a pointer to the Microsoft Exchange Server Distinguished Name (DN) that cannot be migrated to another organization. This information is only retained when using the Microsoft Exchange Task Wizard to move the mailboxes between Exchange servers within a site.

One BlackBerry Enterprise Server cannot provide email redirection for two different Microsoft Exchange organizations.

Migrate BlackBerry Enterprise Server to a different organization

1. Remove BlackBerry Enterprise Server from the originating domain and organization.
2. Move users and mailboxes from one domain and organization to another.
3. Reinstall BlackBerry Enterprise Server.
4. Add the BlackBerry Enterprise Server to the BlackBerrry Servers object in Exchange Administrator > Site> Configuration, if using BlackBerry administration extensions or into the appropriate routing group, if using BlackBerry Enterprise Server management console.
5. Add the BlackBerry device to the BlackBerry Enterprise Server.
6. For BlackBerry Enterprise Server version 4.0 and 4.1, erase the data and applications from the BlackBerry smartphone (for instructions, see KB02318), and perform and enterprise activation. For BlackBerry Enterprise Server version 3.6, connect the BlackBerry smartphone and generate an encryption key.
