Legacy is here to stay... Live with it...
"Legacy software" or more generall "Legacy IT" is usually discussed as if it were some anomalous hangover from the bad ol' days, from old, undesirable and badly regarded projects, or from when things "weren't done properly."
Well, that's clearly wrong... Legacy is and always will be a fact of every project. If not now, then sooner or later.
It's unfortunate that Legacy software is most often mentioned in the same statements that tells us about the bright new future ahead, with no more Legacy software to hold us back, to drag down performance and to remove the need for software maintenance.
Let's help inject some realism into these discussions and remind everyone that focussing on the good news and the bright future that lies ahead is no way to run projects that we know will have problems. We know that. That's life...
I hope they don't imagine a problem-free follow-up and then forget any lessons learned... we don't learn from the good news, so relish the bad news...
