Method for transferring applicative data between two instances of an application

摘要

The invention is a method for transferring applicative data from an instance of an old package to another instance of a new package corresponding to an upgraded version of the old package. Each instance stores the applicative data using its own storage format. These instances are embedded in a secure element. The method comprises a step wherein the secure element receives a first command containing a script able to automatically convert the applicative data from a storage format into the other storage format, and a step wherein the secure element executes the script, updates the applicative data of the new instance and delete the old instance when a predefined event occurs.
