You can lift and shift data by moving the storage from the original source system and reconnected it to the target system. This task can be accomplished by physically recabling the devices, or by using multiported devices such as the devices on a SAN or iSCSI network. Each storage type requires a particular set of administrative actions.
Stop any applications that might attempt to access the storage that you plan to remove.
Backup the source system data.
Additional administrative tasks are usually needed to logically remove the storage from the source system. The tasks differ based on the type of storage and file systems. Here are some common tasks:
ZFS – Run the zpool export command. This unmounts file systems and removes the zpool from the source system. For more information, refer to: https://docs.oracle.com/cd/E19253-01/819-5461/gbchy/index.html
UFS and NFS – Use the umount command to unmount the file systems. Also consider removing the file systems from the /etc/vfstab file to prevent the system from attempting to mount the removed file systems. For more information, refer to How to Unmount a File System at https://docs.oracle.com/cd/E26505_01/html/E37385/fscreate-6.html#scrolltoc
ZFS – Run the zpool import command. to discover and import the zpool. For more information, refer to: https://docs.oracle.com/cd/E19253-01/819-5461/gbchy/index.html
Fibre Channel configured LUNs – Perform the ZFS SAN Fibre Channel Configuration procedure that is described here:
iSCSI configured LUNs – Perform one of the Configuring iSCSI procedures that are described here:

Follow one of the following migration procedures before starting SVM, ZFS or VxVM configurations on the target system.
ZFS –

NFS mounts – Create target NFS mounts that are same NFS mounts seen in source system.
On ZFS Storage side, add NFS node exceptions for accessing NFS file system, that are similar to source config.
Update the target system /etc/vfstab file for NFS mounts that match with source system. and create mount points and mount file system.
SVM –

Without metasets:

VxVM –
Follow the Veritas/Symantec documentation for exporting Veritas disk groups from source system and importing them on the target system.
