When you switch to a new BlackBerry smartphone your data and settings, such as supported email messages, organizer data, and compatible third-party applications, can be transferred to your new smartphone.
The backup and restore process can be done using a media card or the BlackBerry Device Software. Both options are available from the Device Switch option in the Setup application.
A Switch Smartphones user guide is available at docs.blackberry.com.
Depending on your wireless service provider, this feature might not be available.
