It might be that Preupgrade has bugs.   Reporting them and getting it
fixed would be the first choice rather than replace it with a script
which will likely have bugs as well.  It is not realistic to believe
that you can write a script to handle upgrades and not have bugs.
Upgrading a distribution is a fairly complex process to say the least.
