   Based on previous discussions then there are several "If it ain't   
   broke, don't fix it." people here.   
      
   But I do not consider myself one of them.   
      
   You evaluate benefits, cost and risk of upgrade projects   
   and decide based on that analysis.   
      
   And long term it is not so much a question about IF but more   
   a question about WHEN and HOW. Is it now or in 3 years or in   
   10 years? Just add functionality or rewrite some old parts   
   or rewrite everything?

   I don't see how one mistake being more common than another   
   mistake relates to right or good idea.
