We are running our controllers as hosts to different customers.
We have FAS3270 active-active configuration providing NAS shares over CIFS and separate customers with vFilers.
We have a large amount of windows servers (both 2003 and 2008) that hosts these files today.
And we want to move them to the NAS environment in our FAS3270.
So far we have handled it with Robocopy, and it has worked OK.
But now, we are stuck with two different customer cases.
One is a 2003 server and the other is 2008 and the problem is that robocopy is taking 20-30h to do a final sync, and the customer wont accept that timeframe.
I have now tried out OSSV on the 2008 server and must say it works really good.
But the last part of the migration process is still the most tricky.... moving the share structure... how do you do it?
One customer have 200 shares on their windows fileserver, and doing all those manually is a pain in the b#tt.
1. what tools do you use to move data (Robocopy, OSSV etc)
2. How do you migrate the share structure?
I have found a KB how to export and impport share structure, but that only applys to Windows server (http://support.microsoft.com/kb/125996)
Is there a way to import the shares to our NAS environment?
Solved! SEE THE SOLUTION

For migrating data, I have always used rsync in the unix world. Even very large filesystems give a very quick final sync. Seems to me that there are several rsync ports to windows - you might try one of these to see if you get better performance.
As for importing the shares, I think you're stuck doing it manually. If there was a way to export the existing shares into a text file, there would be a pretty good chance you'd be able to manipulate the data into the ONTAP commands for creating the shares - but I'd have to see it....

if you have some money to spend, you can use Secure Copy
it's possible to rent a temporary license for that software
May be it'll be faster than Robocopy as it runs in multi thread
the big advantage of the product is the capacity to migrate Windows shares (also user and local group)
We used it for a large project with more than 6000 shares

Radek, the OP is migrating from windows to NetApp, so there is no cifsconfig_shares file to copy.
In addition to the cifsconfig_share file (just in case someone else trying to migrate shares from NetApp to NetApp reads this), there is some share information kept in the registry. Look for "options.cifsinternal.share" in the /etc/registry. Only some options are here (umask stuff, at least) - there may be no entry for some shares.
cifs shares -add "test" "/vol/vol0/etc/log" -comment ""
cifs access "test" S-NONE "nosd"
$ grep options.cifsinternal.share registry

Ok.. so you telling me if I use SecureCopy I can migrate both files, folder structure AND shares?
From Windows fileserver to NetApp NAS/CIFS?
No need to manually configure the shares on the NAS filer afterwards?
For one customer we are talking about 10TB data and +200 shares.
