Every now and again we have to deal with a sudden requirements change. When that happens, we sometimes just need to take a step back and evaluate the entire situation to ensure we are proceeding down the right path. It is better to be pensive about the course of action rather than to knee jerk into the course of action. Do you want to spend 5 minutes on the solution or 30-40 minutes doing the same thing? Changing collation can be an easy change, or it can be one met with a bit of pain doing a reinstall (more painful if more user databases are present). Keep that in mind and keep cool when you need to make a sudden change.
