Abstract
Systems, methods, and computer-readable media for preserving trust data during operating system updates of a secure element of an electronic device are provide. An update package is received to update an existing secure element operating system to a new secure element operating system by exporting trust data from the existing secure element operating system, after the exporting, uninstalling the existing secure element operating system, migrating the exported trust data using a migration operating system when a data format version of the existing secure element operating system is different than a data format version of the new secure element operating system, installing the new secure element operating system, and importing the migrated trust data into the installed new secure element operating system.
