Dell EMC Metro node 7.1 Administrator Guide

About thin migrations

Metro node supports the migration of a thin volume to another storage array.

For a thin volume to support the thin storage management features after a migration, both the source and the target volumes must be created from the same storage-array family. If they are created from the arrays that belong to different storage-array family, the thin-enabled attribute is retained as true, the thin-capable attribute is set to false and the UNMAP command is rejected.

Migrating thin capable storage provides you additional information on the thin storage migrations.
