We have a policy that no user will be left behind as a result of technology changes. A perfect example of this is our old DOS software. Even though there are only a handful of users left, we will still take their support calls and assist with any question. While there is a cost in maintaining the knowledge, it provides peace of mind and evidence that we don’t cut and run when new technology is released. Sure, we would like everyone to leave DOS behind – but we do not force people.
