Oops, there seems to have been a mistake, indeed. -nodelete is available
for vos restore, which you can perform subsequent to vos dump.

Dump all volumes to files and restore them on the new server. This even has
the added benefit that as long as you retain the dump files, you have an
additional layer of data safety.

Use vos restore -nodelete to follow the original instructions.

You may want to declare a downtime for the volumes in question for this 
two-step move operation, though. This is not necessary when using vos 
move. Your choice. There are virtually no risks in doing "vos move" that I 
am aware of.
