[Info-vax] From ODS-2 to ODS-5

   If you want a backup, then make a backup.  Then SET VOL. 
Why waste the time on what should be a pointless restore
operation?

   If I wanted to test SET VOL, then I'd play with some
unimportant disk.  Virtual, probably.

   It's been a _long_ time since I switched to ODS5 system
disks for non-VAX systems (and SET PROC/PARS=EXTE, too), but
I believe that I did at least one using SET VOL.  As I
recall, it took approximately no time.

   _Which_ "the various sizes"?  Why would the size(s) of an
existing file change?  If the cluster size changes, then I
might expect a _new_ file to differ from a similar old file. 
I don't see /CLUSTER_SIZE among the options on SET VOLUME.

   If you _want_ a newer/better/smaller cluster size, then
INIT (and BACKUP) might be a better choice than SET VOL.

   You might be thinking too hard about this.
