Jessica,
 
ndmpcopy, at the command line of a UNIX admin host works very well, particularly if you have a GbE (Gigabit Ethernet) connection for filer to filer data migration at any level - volume or qtree, even data from one location to another on the same filer. The form I use is:
$ ndmpcopy filer1:/vol/volname/qtree filer2:/vol/volname/qtree -sa root:password -da root:password -dhost GbE_IP_address -level 0-9
ndmpcopy is downloadable, compiler for Sun, from the site: http://www.ndmp.org/
 
If you have a license, SnapMirror works really well too, but at the volume level. More to setup but less impact if outage is required.

Subject: Data Copy from Filer to Filer

What are your recommendations of copying data from one filer to another?

I have estimated time of 28 hours to transfer 70 GB via a copy command on the host machine.

I have tried to copy via CIFS accessing from NT servers using drag and drop.  Encountered errors which halted the copy process due to files that were linked to incorrect locations.  Unix files in the users desktop were linked to other machines and the path was invalid.  Did a grep to locate these linked files in the user folders, and found too many to change one by one. 

The vol copy command is only useful when copying from volume to volume on the same filer, correct?

I am looking for the most efficient way to move data.

Any suggestions would be great!
