SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Guides teams to plan and execute system, language, framework, and data migrations while minimizing downtime, preserving data integrity, and ensuring safe rollbacks.

Core Features & Use Cases

  • Strategy Selection: Recommends Big Bang, Strangler Fig, Parallel Run, or Branch by Abstraction based on code size, team size, and data criticality.
  • Zero-Downtime Data Migration: Dual-write, backfill, verification, and phased cutover with match-rate targets.
  • Operational Safety: Feature-flagged deployments, automated rollback triggers, iterative component extraction, and two-week stability retention before removal.
  • Use Case: Move a large monolith and its database to microservices while keeping live traffic and ensuring >99.9% behavioral parity before cutover.

Quick Start

Ask the migration skill to assess your source and target stacks, propose a phased migration strategy, and generate a step-by-step rollout and rollback plan.

FAQPage Schema
How do I perform a zero-downtime database migration without losing data?▼

Zero-downtime database migration uses dual-write, backfill, and verification phases to sync data, followed by a phased cutover with match-rate integrity checks to ensure behavioral parity before switching traffic.

What is the best way to migrate a monolith to microservices while keeping live traffic?▼

Migrating a monolith to microservices safely uses the Strangler Fig pattern for iterative component extraction, feature-flagged rollouts, and automated rollback triggers to maintain live traffic stability.

How does the Strangler Fig pattern work for system migrations?▼

The Strangler Fig pattern works by iteratively extracting components from a legacy system, routing traffic to new implementations via feature flags, and retaining old components for two weeks of stability before removal.

Can I use feature flags to manage rollback triggers during a data migration?▼

Feature flags manage rollback triggers during data migration by controlling traffic routing, allowing automated rollback if match-rate integrity checks fail or behavioral parity drops below acceptable targets.

When do I need a dual-write and backfill verification process for data migration?▼

You need dual-write and backfill verification for data migration when moving large monoliths or critical databases, ensuring >99.9% behavioral parity and zero downtime before the final cutover.

Does this migration strategy support a REST to GraphQL transition?▼

This migration strategy supports REST to GraphQL transitions by assessing source and target stacks, recommending phased rollout strategies, and generating step-by-step rollout and automated rollback plans.
