Moving a Unit from One Controller to Another After you have configured a unit on a 3ware 9000 series controller, you can move it to a different 3ware 9000 series controller, and retain the configuration on the new controller. This is referred to as "array roaming." When connecting the unit to the new controller, you do not have to physically connect the drives to the same physical slots to which they were connected on the previous controller. The firmware will still recognize the unit. This feature is referred to as "disk roaming." 138 3ware SAS/SATA RAID Software User Guide, Version 9.5.1
