I've got to migrate some data from 32 bt to 64 bit volumes and, unfortunately, this is OnTap 8.02 so snapmirrr and vol move are out of the window so I'm going to use NDMPCopy but I've found that with NDMPCOPY when the cli closes the copy is killed.
Is there any way to prevent this or to keep the copy going if the CLI gets disconnected?

the NDMPCOPY command should not be interrupted if the console session times out. As was suggested, use the SP or RLM port to connect, either that or connect directly to the phyical console.
Have you looked at Qtree SnapMirror (QSM) to migrate the volumes from 32b aggr to 64b aggr? This is how I migrated from ONTAP7 to ONTAP8 when 8.0 was first released.

You're in a tough spot.
Maybe try issuing the ndmpcopy command via a remote call? For example, from my Linux desktop, I can do something like 'ssh root@filer ndmpcopy <options>'. I've never tried issuing an 'ndmpcopy' that way, but it may be worth a shot.

Technically it is on a qtree as each FlexVol root is a qtree by default. Don't beleive me? Run 'qtree status' on your controller.
But in this case, it needs to be snapmirrored to a Qtree destination.
So Toaster1\Vol1 would need to be snapmirrored to Toaster1\Vol2\Qtree1
The command would look like this:
snapmirror initialize -S toaster1:/vol/vol1/- toaster1:/vol/vol2/qtree1
