Over $600 million in lost business occurred as a result of this.
That is not to say that nobody should attempt such IT projects because of the potential for disaster. There are also stories of companies that were amazingly successful with their projects. In all of these cases, the companies often spent tireless months just in the planning stages. Every angle was looked at and almost all possible scenarios were reviewed. Having the fewest amount of surprises is usually what makes thing go the smoothest.
There are a lot of risks involved with any IT project, but it is just as risky to not make important updates and changes. If you plan things out, it will hopefully go smoothly and even benefit the business in the long run.
