This example describes a one-time migration of data between two operating systems. Some of the following steps require a backup of the file system to be created. To simplify the process, you can create one backup before performing any of the steps instead of creating multiple backups as you go.
To perform a one-time migration
If the underlying Volume Manager storage is not contained in a CDS disk group, it must first be upgraded to be a CDS disk group, and all other physical considerations related to migrating the storage physically between systems must first be addressed.
Use the following command to ensure that there are no files in the file system that will be inaccessible after migrating the data due to large file size or to differences in user or group ID between platforms:
# fscdsadm -v -t target mount_point
# umount mount_point
Make the physical storage and Volume Manager logical storage accessible on the Linux system by exporting the disk group from the source system and importing the disk group on the target system after resolving any other physical storage attachment issues.
