Discontinue the use of deprecated technologies and migrate off the use of deprecated technologies in a timely, methodical manner.
Deprecated technologies are technologies which have been replaced by newer technologies. Features typically get marked as "deprecated", rather than simply removed, in order to provide backward compatibility for software users. When other programs depend on the deprecated feature, their programmers need time to change their code to avoid the feature.
Maintain a local Deprecated Technologies list.
Information solutions involve a multitude of technology choices. Which technologies are deprecated can be subjective and maintaining a list of deprecated technologies gives developers and purchacing agents guidance.

Best Practice:  Discontinue the use of deprecated technologies and migrate off the use of deprecated technologies in a timely, methodical manner.
