BACKUP the original!!!  You need to be able to prove that the old sucked and the new... sucks 
less... (you can only fix what you find).

Then you need to start a document of each thing like this that you find.  It will provide a huge 
evidence base for when you present the case for "your application sucks and this is why it takes so 
long to get it working".
