What does a 'plunge' refer to in system conversion?

In the context of system conversion, a 'plunge' refers to a simultaneous switch to a new system, often referred to as a "big bang" approach. This method involves stopping the old system and immediately starting the new one, with the transition occurring at once rather than in stages.

This approach can be beneficial for its immediacy and simplicity; it avoids the complexities that come with running two systems in parallel or transitioning gradually. However, plunge conversions can also pose significant risks, such as potential downtime or data loss if there are unforeseen issues during the switch.

Other methods of system conversion, like gradual implementation or phased transition, involve a more staged approach, allowing for continuity and reduced risk but potentially prolonging the transition period. Evaluating system performance is a separate concern not directly related to the nature of the conversion itself.
