I disagree, we have copied numerous Terabytes of Data from NT/Novell servers to Filers using Robocopy. I am not saying it is the best solution but the best we found with keeping ACLs in place.

A coworker of mine states that running robocopy on a multi-CPU box copying data from NTFS partitions with compression turned on will never finish. There is a utility called imagecfg.exe that allows you to create a copy of robocopy.exe which assigns it to a given CPU and does not allow it to change between CPUs.
If you want a copy of this utility, contact me directly. If you're not using NTFS with compression enabled, disregard this :)

Hi Toasters,
we're in the process of consolidating NT file services on a NetApp
Filer. We
have an F810 where we want to store all our user's data which is now
spread
across multiple servers, some of which are close to being maxed out. We
now
have the problem of moving all the data while we're still servicing our users - we're on 24/7 here. We found that copying the data to the filer
is
painfully slow; we're suspecting that NT ACLs might be the culprit.
We've
tried robocopy, secure copy and xxcopy to no avail - moving a small part
of
the total data took 15 hours. Anybody out there willing to share their experiences with moving several hundreds of GB across the network? We
need
to keep NT permissions, obviously. On the mailing list I saw references
to
Fastlane and Aelita's SCW - any experience with those or other 3rd party products?
Greetings and thanks in advance
Bernhard
