   But not bad assumptions.   
      
   I would summarize the numbers as:   
   - it cost 500-700 K$ per year to maintain app no matter   
      platform   
   - it would cost 300 K$ to migrate 1:1 from VMS Itanium to VMS x86-64   
   - it would cost 3 M$ to migrate from Cobol/VMS   
      to common tech stack/Linux   
   which respectively:   
   - is irrelevant for the conclusion   
   - is somewhere in the realistic to slightly optimistic range   
   - is very optimistic for 1 MLOC (I would have said 10-20 M$!!)   
      
   There is absolutely no doubt that VMS x86-64 is the lowest   
   cost solution.   
      
   The downside is that it is 1:1 so still Cobol, Rdb and   
   DECForms.
