Phase 1: Detect Versions

Get Ground Truth

# Installed versions
npm ls @assistant-ui/react @assistant-ui/react-ai-sdk ai @ai-sdk/react 2>/dev/null

# Latest from npm
npm view @assistant-ui/react version
npm view @assistant-ui/react-ai-sdk version
npm view ai version

Version Analysis

ai

@assistant-ui/react

@assistant-ui/react

@assistant-ui/react

@assistant-ui/react-ai-sdk

Phase 2: Route to Migration

AI SDK < 6.0.0?
├─ Yes → See ./references/ai-sdk-v6.md
└─ No
   └─ assistant-ui outdated?
      ├─ Yes → See ./references/assistant-ui.md
      └─ No → Already up to date

Migration Order

1. AI SDK first (if < 6.0.0) - Required for @assistant-ui/react-ai-sdk >= 1.0
2. assistant-ui second - Apply breaking changes for version jump
3. Verify - Type check, build, test

Phase 3: Execute

Update Packages

# pnpm
pnpm add @assistant-ui/react@latest @assistant-ui/react-ai-sdk@latest ai@latest @ai-sdk/react@latest

# npm
npm install @assistant-ui/react@latest @assistant-ui/react-ai-sdk@latest ai@latest @ai-sdk/react@latest

Apply Migrations

Verify

npx tsc --noEmit  # Type check
pnpm build        # Build check

Troubleshooting

• Update all packages together
