It's a good thing if the environment around your VB6 stuff can still work with it, or accept it. Many systems get replaced when the substrate they run on is no longer supported as in "won't run on any hardware still in its warranty cycle or with parts available", or everything around has changed and the layer of glue needed to keep the old system alive and talking to everything else has grown to be prohibitively complex and expensive and is now more like a load-bearing structure by itself. If you can replace it and also fire warm bodies who used to keep it alive by being the irreplaceable wizards with arcane knowledge and job security, it just might be a net win. I hear tales about several layers of emulators the sources for which are forever lost, with the bottommost of them running some very mission critical early COBOL or ALGOL-69 (or Lisp, who knows) code written back in the days when it had been that newfangled thing young guns liked, and which no one now can reimplement today (maybe because elves have died out from smog and the golden age is over), but they may be bunk.
