6.4.3 PS Series replication
PS Series replication can be used to migrate volume data. Volumes can be migrated using either standard
asynchronous replication or in firmware version 6.x and higher synchronous replication.
Asynchronous replication moves data between PS Series groups while synchronous replication moved data
between storage pools within the same PS Series group. For more information regarding replication options
and setup, refer to the PS Series Group Administration guide http://eqlsupport.dell.com then “Downloads ->
PS Firmware”.
6.5 Backup and restore
Lastly, traditional backup and restore options can also be used to migrate data from one array to another with
a different RAID policy. These methods usually require downtime and can be lengthy depending on the size
of the data being moved.
