Code Migration Planner

The Challenge

Major migrations — React upgrades, TypeScript conversions, API versioning — require extensive planning. Understanding the scope, dependencies, and risks takes days of analysis.

The AI Desk Solution

AI Desk analyzes your codebase and generates comprehensive migration plans with effort estimates.

The Workflow

Step 1: Define Migration

Input: "Plan React 17 to 18 migration"
Sources: GitHub repo, dependencies, existing issues

Step 2: Codebase Analysis

• Identify affected files
• Map dependencies
• Flag breaking changes
• Estimate complexity

Step 3: Migration Plan

📋 Migration Plan: React 17 → 18

SCOPE ANALYSIS
├── Total components: 247
├── Affected: 156 (63%)
├── High complexity: 23
├── Dependencies to update: 12
└── Estimated effort: 3-4 sprints

BREAKING CHANGES DETECTED

Automatic Batching (High Impact)
├── Affected: 34 components
├── Pattern: setState in callbacks
├── Fix: Add flushSync where needed
└── Effort: 8-12 hours

Strict Mode Changes (Medium Impact)
├── Affected: 12 components
├── Pattern: useEffect cleanup timing
├── Fix: Update cleanup logic
└── Effort: 4-6 hours

Removed APIs (Low Impact)
├── Affected: 3 components
├── Pattern: ReactDOM.render usage
├── Fix: Migrate to createRoot
└── Effort: 1-2 hours

DEPENDENCY UPDATES
├── react-router: 5.x → 6.x (breaking)
├── styled-components: ✓ compatible
├── react-query: ✓ compatible
└── formik: ✓ compatible

RECOMMENDED APPROACH
├── Phase 1: Update dependencies (1 sprint)
├── Phase 2: Fix breaking changes (2 sprints)
├── Phase 3: Testing & rollout (1 sprint)
└── Risk buffer: +20% for unknowns

Value Proposition

• Time Saved: 8 hours of analysis
