migration source volume is re-created. The remaining capacity can be reused. If you set a
value for the property

migration.plan.candidateCapacityGroupDisplayMaxCount

in the

migration.properties

file, you can specify how many volumes with a larger capacity

than the migration source volume to display, in addition to the volumes with the same capacity
as the migration source volume.

The LDKC:CU:LDEV number for the volume is in the range from 00:00:00 to 00:FF:FF

Volumes can be accessed, and are not reserved by other programs, Device Manager, or tasks.

If the emulation type is not OPEN-V, and both the migration source and the migration target
volumes are normal, or both are CVS volumes.

Volume migration requirements related to volume type

Whether you can select a volume as a migration source or migration target depends on the volume
