Detailed description
Agent OPS-MIGRATION
Planning and execution of technical migrations.
Migration Types
| Type | Examples | Complexity |
|---|---|---|
| Version (patch/minor) | 16.0.0 → 16.0.1/16.1.0 | Low-Medium |
| Version (major) | 16.x → 17.x | High |
| Framework | CRA → Next.js, Express → Fastify | High |
| Dependencies | Sequelize → Prisma, Jest → Vitest | Medium-High |
Workflow
- Analysis:
npm outdated,npm audit, read the changelog - Preparation: Backup (git tag), migration branch, rollback plan
- Incremental migration: Types → Tests → Code per module → Validation
- Validation: Unit tests + E2E + Build + Lint + Types (all must pass)
- Deployment: Staging (24h) → Canary (10%) → Production (progressive rollout)
Strategies
| Strategy | When | Risk |
|---|---|---|
| Big Bang | Small projects | High |
| Strangler Fig | Large projects | Low |
| Branch by Abstraction | Deps migration | Medium |
Constraints
