SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Efficiently plan and execute deprecation with safe migration paths for legacy systems and features, reducing risk and maintenance cost.

Core Features & Use Cases

  • Deprecation planning: define lifecycle, decision criteria, and timelines for old systems.
  • Migration strategies: apply strangler, adapters, or feature-flag approaches to move users safely.
  • Governance & risk controls: provide checklists, migration guides, and verification steps to ensure minimal user impact.
  • Use Case: sunset an API and guide customers to a replacement with a clear migration path and tooling.

Quick Start

Generate a deprecation and migration plan that sunsets a legacy API and migrates users to the new implementation.

FAQPage Schema
How do I plan a safe API sunset and migration for legacy systems?▼

Feature flags allow safe migration by routing user traffic between legacy and new implementations dynamically. This migration strategy enables testing new system features incrementally, ensuring verification steps pass before fully retiring the old legacy system.

What is the strangler pattern for migrating legacy features?▼

Migration governance provides checklists, migration guides, and verification steps to control risk during system deprecation. It defines lifecycle timelines and decision criteria, ensuring customers follow a secure, user-friendly transition path when moving to replacement features.

Can I use feature flags for deprecating old system features?▼
