Install Script to upgrade server from 2.x ifix5 to ifix7

I am trying to update a 64 bit linux server from ifix5 to ifix7. I got it working, but am having issues. I would appreciate if folks could validate the below update script and let me know if I am copying over any config files from ifix5 that I shouldn't or am not copying something that I should.

echo "SHUTTING DOWN SERVER"

server/server.shutdown

sleep 5

echo "REMOVING OLD RTC FILES"

rm -r /opt/app/jazz/server

rm -r /opt/app/jazz/repotools

sleep 5

echo "COPYING NEW RTC FILES"

cp -rpf /opt/app/jazz/install/rtc7azip/* /opt/app/jazz

sleep 5

echo "RESTORING OLD CONFIG FILES"

tar --overwrite --same-owner -xpf backup/backup-2011-10-31.tar server/conf

tar --overwrite --same-owner -xpf backup/backup-2011-10-31.tar server/repositoryDB
