I added this before I followed up to this thread with
"Don't try this (dump partial DB and transfer):


WARNING WARNING WARNING: If for some reason you want to reset your 
entire RT instance's TICKETS AND TICKET DATA ONLY (and keep Scrips, 
Custom Fields, etc), you could do something like the following. This was 
useful for me when I wanted to take our production RT instance and 
duplicate it onto a development box but not have the huge database full 
of tickets and ticket-related data.

Bourne shell syntax is shown below:

cd /tmp
while :
SHREDDED=`rt-shredder --plugin "Tickets=query,id > 0;limit,100" --force 
--sqldump foo.sql 2>&1 | grep RT::Ticket | wc -l`
echo "Shredded roughly $SHREDDED tickets."
sleep 3 # let the system get a breath
rm -f foo.sql # we don't care about restoring what we shredded in this case
if [ $SHREDDED -eq 0 ]; then
