It sounds like a bug of course.  We took a different approach a few years
ago when we transferred our application from SCO to an HPUX server.  First I
obtained a program to document our indexes into a file, and one that could
read the file and re-build the indexes - I had written one in the past but I
had lost it somewhere along the way.  I believe I ended up downloading these
from Nancy's site and modifying them slightly so that they would run on the
HPUX server.

Then I created a list of all the filepro files (directories) in the filepro
directory.  There were about 2000 at that time.  I split this list up into
about 8 pieces, and then I created a script created a tar file (excluding
indexes) for each list, then ftp'd the tar file to the HPUX server, then
deleted the tar file.  On the other side I had a script that un-tarred the
file and then deleted the tar file.

Then I had a script that ran swapcpu on all of the filepro files on HPUX,
and then finally build the indexes.  There were other minor issues also -
for example swapcpu did not like zero length output formats - I ended up
searching and destroying those first.

It was about 8 gig total that was transferred, so I had both the push and
the pull side going at the same time - I don't remember how long it took
start to finish.  I suspect it was overnight starting at around 5pm and then
into the next morning.

Coincidentally we also had problems with long file names on the 4.8 HPUX
version that we transferred to.  However the files did transfer it was just
that 4.8 could not see them.  Luckily, we did not have very many of these.
