I will be working on a system which will be ported over from Java to .Net. It is a pretty big system. I don't have any specifics about how the system is designed, no documentation, nothing.
You know as much about it as I do at this point. Apparently no one else does either, so I have been tasked to figure it out and then rework the system.
My question is, does anyone have any advice on the steps I should take to learn the systems design?
