OVDB upgrade question.

[Jaye Mathisen]

Going to upgrade from a late July to release to the 10-02 release.  The
db_upgrade procedure mentions using the -s option to handle duplicate
keys.  I don't believe there should be duplicate keys in the overview
data, so this should be a non-issue, but I'm not sure if it still makes a
difference on the on-disk structures, per the man page.

So if anybody has done this, which option did you use?
