Updating a metadata structure for a firmware update

Abstract:

The present disclosure relates to a method for updating a metadata structure to be compatible with an update between the first version of firmware and a second version of firmware, including formation of migration data (e.g., migration arrays) associated with corresponding blocks of metadata for different versions of firmware, and comparing of attributes of the migration data to determine various migration actions to perform in generating an updated metadata structure that is compatible with an update between versions of firmware.
