Can I just double check that the editing of fstab is only applicable if 
my device names change?  During my testing here I have been migrating to 
a secondary disk that eventually becomes the primary.  As such I haven't 
had to change the fstab (both origin and eventually destination are 
device ad0).  When I do this for real however, I will be migrating from 
a single drive to an array so understand that in that case I will need 
to edit fstab to reflect the device change (this should be fine as I 
have had to do this in the past).

Thanks, I'd already read the faq and the bsdvault procedure is very 
similar in content.  I just wondered if there was any better/other ways 
really..

Thanks for your help,
