Migrating to/from Other SMART
Array Controllers
The table below indicates what actions, if any, are required when migrating
from one array controller type to another within the SMART family of
controllers.
NOTE
: It is recommended that any time you move drive arrays or change
your configuration you should back up data.

Legend:
X: No action required. Recommended back up of data prior to migrating to another controller.
BU/Restore: Mandatory data back up and restore to prevent data loss.
FW Upgrade: Upgrade of SMART-2/E or /P Controller FW to v1.90 or later is recommended to
allow connection of drive arrays to either SCSI bus. However, if a logical volume spans both
ports, the drives must be connected to the same port as they were with the original controller.
In all cases drives within a volume must keep their same relative order.
