  • 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.
