7.3 Copying Files from DAS Volume to Xsan Volume
Now you can start the standard file copy from your DAS volume to the Xsan volume as shown below,
and get ready to retire your DAS volume.
Note that once the file transfer process starts, you should no longer modify data on the DAS and only
work with files that are relocated to the Xsan volume.
7.4 Repurposing the DAS RAID to Enlarge the Xsan Volume
After all the files have properly migrated to your Xsan volume, you are free to reformat your DAS PCIe

ExaSAN storage.
