data migration

  • The process of moving data from one storage source or device, such as a database or tape, to another.
  • The automatic transfer of information between storage media with different priorities. For example, the movement of data from a lower speed medium, such as an optical disk, to a hard disk when needed. This allows more data to be stored than if all was in the higher speed, and hence more expensive, medium. Also called hierarchical storage management.
