Porting Applications from HP Tandem Nonstop to Windows - Large Software projects.

I am currently working on a very large software project at work.  This project is a goverement mandated change that is affecting a large part of most of the systems I work on. 

I am currently building 4 new components as part of my change with several of the changes being ports from a HP Tandem NonStop environment to the our Windows environment.  They are porting these applications due to most of the new functionality being written in WCF and it is just much faster to process the new component on Windows than to link in from Cobol programs to the WCF service.  Other issues are most of the new databases are on the Windows side so again it is just faster to do the processing on Windows.

It really seemed like once they made the decision to move the first process to Windows it opened the flood gates.  They quickly started moving applications that they were having problems designing solutions for on the NonStop to Windows where the solutions were almost trivial. 

This is not the first time I have gone through these excercises.  Actually it seems like I have been going through this type of effort ever since I started working on software.  It really seems to go through phases.  Every few years they will decide it is time to make the leap.
