SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the high risk and uncertainty of brownfield software migrations by ensuring that the new implementation maintains exact behavioral parity with the legacy system.

Core Features & Use Cases

  • Parity Contract Generation: Automatically creates Gherkin scenarios based on legacy behavior to serve as the source of truth for reimplementation.
  • Migration Strategy Planning: Formalizes the migration path, including paradigm shifts, risk assessment, and cutover procedures.
  • Use Case: When moving a legacy monolithic application to a modern microservices architecture, this skill ensures that every critical business flow is documented and tested against the original system's logic.

Quick Start

Run the dare-migrate skill after initializing your migration project to generate the parity scenarios and migration strategy documentation.

Frequently Asked Questions about dare-migrate

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I ensure behavioral parity during a legacy system migration?▼

To ensure behavioral parity during legacy migration, you can generate Gherkin scenarios that document critical legacy business flows to serve as executable contracts for the target reimplementation.

What is the best way to plan a brownfield software migration to microservices?▼

Planning a brownfield migration involves formalizing the migration path by assessing paradigm shifts, evaluating risks, and defining cutover procedures to safely transition legacy systems to modern architectures.

How do I generate Gherkin scenarios from legacy application behavior?▼

Generating Gherkin scenarios from legacy behavior requires existing migration facts and DNA artifacts to architecturally align the semantic mapping and automatically produce parity-focused test contracts.

Do I need migration artifacts before starting a DARE methodology migration?▼

Yes, the DARE methodology requires existing migration facts and DNA artifacts as prerequisites to ensure architectural alignment and behavioral consistency before generating parity scenarios.

When should I not use automated parity contracts for reimplementation?▼

Automated parity contracts may not suit reimplementation efforts lacking existing migration facts or DNA artifacts, as the semantic mapping requires established baseline documentation to ensure architectural alignment.

Can I use this approach for monolithic to microservices migration?▼

Yes, this approach supports monolithic to microservices migration by documenting every critical business flow and testing the new implementation against the original legacy system's logic.
