Data migration

Migrating data between storage units requires the use of the Global Copy or the Metro Mirror mode or a logical volume manager.

• Migrating data using Global Copy or Metro Mirror
  Migrating data between storage units requires the use of the Global Copy or Metro Mirror function.
• Migrating data using a logical volume manager
  The logical volume manager (LVM) software migrates data at a single logical volume level, a physical volume (DDM) level, or the entire contents of a volume group. The LVM software is different between the operating systems that use it. However, the concepts and commands are similar enough to support this scenario.
