Software Conversion Simulation Mode

Abstract:

Simulated software conversion offers advance warning of possible issues that may arise during a full conversion process. An engine interposed between a planner and an upgrade module interacts with the planner and an upgrade module to simulate compliance checks, and to reference a data model to simulate conversion tasks (e.g., simplification items, add-ons, custom code). The engine instructs the planner to continue (rather than halt/suspend) iterative interrogation of the existing production landscape to create an un-truncated stack.xml file, even when the planner encounters an unknown/unfamiliar software element. The upgrade module expects an incoming modified stack.xml file as input, that modified stack.xml file including additional information (such as a flag) referenced by the upgrade module to perform conversion compliance checks and other conversion tasks. The engine enriches the full stack.xml file received from the planner, creating the modified stack.xml file including additional information sent to the upgrade module.
