The following information applies to both SMS-managed and non-SMS-managed data sets.

Task: Migrate one or more data sets to migration volumes.

The data set migrates to a level 1 migration volume unless you specify the MIGRATIONLEVEL2 parameter in the command or you are in an environment that migrates directly to migration level 2 volumes. An SMS-managed data set, for example, can migrate directly to a level 2 volume if defined to do so by a management class parameter. You can cause a data set on a level 1 migration volume to migrate to a level 2 migration volume if you specify a data set that is already on a level 1 migration volume and you specify the MIGRATIONLEVEL2 parameter.

Command migration of SMS-managed data sets is available only for eligible data sets. Data set eligibility is determined by an SMS management class attribute. If you issue HMIGRATE for a data set that is not eligible for migration, the HMIGRATE operation ends and DFSMShsm issues message ARC1245I.

RACF® Authority: To migrate a RACF-protected data set, you must have RACF UPDATE authority to the data set.

Abbreviation: The minimum abbreviation for the HMIGRATE command is HMIG.
