I am trying to move a 4TB volume with a LUN from one aggregate to another to spead out load onto more disks. However I get timeouts all the time at cutover time. I have been unable to figure out why this happens but I am guessing it takes too long time.

It's on " NetApp Release 8.1 7-Mode".
Any suggestions welcome.

So instead of doing vol move, try creating new volume (in the target aggregate) & SnapMirror the content from the old one to the new one.
Some additional info re LUN serial numbers could be found in this thread:

Yes, but then I wouldn't be able to do it without taking it offline?
Anyway I seemed to have solved my problem by increasing the cutover window to 300 seconds and crossed my fingers the server wouldnt throw a fit(it isnt mission crititcal).
