That's not what he's asking.

He has an existing cell with supergroups enabled and a bunch of
supergroups in use.  He accidentally upgraded to a ptserver without
supergroup support.  He's since replaced that with one that does have
supergroup support, but he's wondering if the ptserver without supergroup
support could have corrupted the supergroup portions of his database while
it was running.

I wasn't sure -- I'd heard in the past that people were worried about what
the ptserver might do to the database, but I don't know that specifics
were ever discussed.
