You can.  Moving == copying (but you remove the old
partition from the partition table, and replace it
with the new one)

BUT, the new ext2 partition must be bigger (or the
same size) as the old one.

Also, with the move operation, the new and old
partitions can not overlap.  (If they do, then
you are resizing, and not moving)

Resize-the-start hasn't been implemented for ext2 :-(

If the new and old /usr won't overlap, and the new /usr
is bigger than the old, then you can use the move command.
