Abstract
A system for adapting a legacy system to a new environment includes a method of learning the behavior of a legacy system and a method for replacing a legacy system.Learning the behavior of a legacy system includes gathering information with respect to inputs, outputs, and internal function of the legacy system; defining from the gathered information a set of behavioral rules describing the legacy system; and testing the rules by applying known inputs to the legacy system and verifying that the legacy system responds as predicted by the rules.Replacing a legacy system includes monitoring legacy system responses to legacy system inputs; defining a set of rules describing behavior of the legacy system based on the responses to the inputs; comparing actual legacy system responses to responses predicted by the set of rules; and using the set of rules to create a replacement system that mimics the legacy system.
