Explanation:

is an optional parameter that you use to transition all eligible SMS-managed data sets from a level 0 volume to another level 0 volume. Data sets eligible only for migration are not processed.

This parameter can be specified only with MIGRATE VOLUME or MIGRATE STORAGEGROUP command.

MANAGEMENTCLASS
Specifies the target management class used for class transition processing. Alias: MC
STORAGECLASS
Specifies the target storage class used for class transition processing. Alias: SC
