Moving a device to a BlackBerry Enterprise Server that uses a different BlackBerry Configuration Database
If you move a BlackBerry® device to a BlackBerry® Enterprise Server that uses a different BlackBerry Configuration Database without using the BlackBerry Enterprise Transporter, you or a user must permanently delete all user data and application data, the device transport key, and the IT policy public key from the device.
You or the user must reactivate the device to generate a new device transport key. The BlackBerry® Enterprise Server that you move the device to must generate an IT policy key pair and digitally sign and send the IT policy and the IT policy public key to the device before the device can communicate with the BlackBerry Enterprise Server.
The BlackBerry Configuration Database that you migrated the device to stores the BlackBerry Enterprise Server name, the device transport key, and the IT policy private key.
