createmigration
DESCRIPTION
The createmigration command performs preparation phase of a migration. Actual data transfer
will not be triggered by this command. This does following for a given set of source volumes while
presenting to 3PAR destination storage system.
NOTE: Can only create one migration at a time per source EMC Storage system.
NOTE: Be aware, the createmigration command may take several minutes to complete.
NOTE: The volume(s) or host specified in the createmigration command are mapped to a
storage group on the associated source EMC Storage system. All LUNs and all hosts in the mapped
storage group will be migrated even if only a subset are entered in the createmigration
command.

For VMAX, use the following format:
Volume <device id>
The <device id> value must be five
characters in length. If the actual device
ID is less than five characters, add “0”
at the front to make five characters. For
example, if the VMAX device ID is
