Non-disruptive Storage Migration
Non-disruptive Storage Migration is a function that migrates the volume data from an old storage system to
volumes in a new storage system without stopping a business server in cases such as when replacing a storage
system.
The connection interface between the migration source storage system (external storage system) and the
migration destination storage system (local storage system) is only FC. In addition, the direct connection and
switch connection topologies are supported.
