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
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.

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!
