Migration is the process of moving data from container to another. This includes migration to and from physical containers (e.g. hard disks) and migration to and from logical containers.

Migration often involves some form of reorganization of the data.

Physical migration includes (but is not limited to):

  • moving data from an old hard disk to a newer one
  • moving data from one server to another

Logical migration includes (but is not limited to):

  • migrating data from one database system to another (e.g. Oracle 10g to MySQL 5)
  • migrating existing web applications from one web server to another
  • migrating a cell phones contact list to another cell phone

In contrast to , the data held in the original system after the migration process has been successfully completed is not necessarily used any more.
