Part V Migrating Data The HP 3PAR Peer Motion feature controls the migration of data from a source system to a destination system. A user can copy the virtual volumes and system configuration information to a new system without changing host configurations or interrupting access to the volumes. Any available free port can be used for Peer Motion. There are three types of migration: online migration, minimally disruptive migration, and offline migration: • Online - Used to migrate virtual volumes that are exported to a host. This migration type requires unzoning the host system from the source system. • Minimally Disruptive - Used to migrate virtual volumes that are exported to a host. This migration type requires shutting down the host system for a short period of time. Additionally, the destination system must be running OS version 3.1.2 or higher. • Offline - Used to migrate virtual volumes that are not exported to a host. Exported volumes that you want to migrate must first be unexported to use offline migration. No unzoning or system shutdown is required. After the data migration is complete, the source system can be disconnected from the hosts and repurposed. "Using the Peer Motion Manager" (page 224) "Migrating Data " (page 231)
