Abstract
A device updating system may store data from an application to be updated, especially personalization data that is to be persisted beyond the version update. After the data is stored, the application may be deleted and a migration application is installed. The migration application may use a matrix or the like characterizing differences between prior editions of the application and the one being installed. The migration application may determine the previous edition and updates the personalization data according to the matrix. After the data is updated, the migration application may be deleted and the new application installed. The new application may retrieve the updated data and may be ready to operate without concern about what the previous edition may have been. Memory space may be conserved by not requiring the new application to carry the version matrix and all possible changes between the current edition and all possible previous editions.
