Digital Migration Approaches

• Four primary types of digital migration in response to motivators, ordered by increasing risk of information loss:

  • Refreshment
    • Media replacement with no bit changes
  • Replication
    • No change to Packaging Information or Content Information/PDI bits
  • Repackaging
    • Some bit changes in Packaging Information
  • Transformation
    • Reversible: Bit changes in Content Information/PDI are reversible by an algorithm
    • Non-reversible: Bit changes in Content Information/PDI are not reversible by an algorithm
