# AQE v2 to v3 Migration Skill

<default_to_action>
When migrating from v2 to v3:
1. ANALYZE current v2 installation
2. BACKUP all data before any changes
3. MIGRATE configuration, memory, and patterns
4. VALIDATE migration success
5. PROVIDE rollback instructions

**Never delete v2 data without explicit user confirmation.**
</default_to_action>

## Quick Reference

### Migration Command
```bash
# Install v3 alongside v2
npm install @agentic-qe/v3

# Run migration
npx aqe migrate

# Or use this skill
/aqe-v2-v3-migration
```

## Migration Checklist

### Pre-Migration
- [ ] Verify v2 installation exists (`.agentic-qe/` directory)
- [ ] Check v2 version: `aqe --version` (should be 2.x.x)
- [ ] Backup current data: `npm run backup` (in v2 project)
- [ ] Note any custom configurations
- [ ] Document current test counts and coverage

### During Migration
- [ ] Install v3: `npm install @agentic-qe/v3`
- [ ] Run migration: `npx aqe migrate`
- [ ] Review migration report
- [ ] Verify data transferred correctly

### Post-Migration
- [ ] Run v3 tests: `npx aqe test`
- [ ] Check coverage: `npx aqe coverage`
- [ ] Verify patterns loaded: `npx aqe patterns list`
- [ ] Test MCP integration with Claude Code
