Consider these points when deciding how to migrate existing data to the Sun Cluster environment.
You cannot move data into the Sun Cluster configuration by connecting existing disks that contain data. The volume management software must be used to prepare the disks before moving data to them.
You can use ufsdump(1M) and ufsrestore(1M) or other suitable file system backup products to migrate UNIX file system data to Sun Cluster nodes.
When migrating databases to a Sun Cluster configuration, use the method recommended by the database vendor.
