$DIR=`pwd`
for SEEN in *.seen; do
  mv $SEEN $SEEN.orig 
  /usr/cyrus/bin64/cyr_dbtool $DIR/$SEEN.orig skiplist show > $SEEN.dump
  /usr/cyrus/bin32/cyr_dbtool -n $DIR/$SEEN skiplist set < $SEEN.dump
done

rm *.orig

Something like that, using the 64bit to dump and the 32bit to write.
You'll see I'm keeping the old seen file as seen.orig.

You can also do these bits on different machines if you can't run
both 64bit and 32bit binaries on the same machine of course...

NOTE - it will be a bit faster if you use:

http://cyrus.brong.fastmail.fm/patches/cyrus-dbtool-transaction-2.3.9.diff

(which also documents the -n option, though it's present in 2.3.9,
 just not documented)

Actually, it shouldn't be too bad for seen files because they don't have
that many records anyway.
