DATABASE_URL=your_production_url pnpm exec prisma migrate deploy

# Verify migration completed
DATABASE_URL=your_production_url pnpm exec prisma studio
```

### 2. Environment Variables
```
DATABASE_URL=your_db_connection
NEXT_PUBLIC_API_URL=your_api_domain
JWT_SECRET=generate_strong_secret
ENCRYPTION_KEY=generate_encryption_key
NOTIFICATION_SERVICE_URL=your_service

docker build -t exametra:latest .
docker run -e DATABASE_URL=$DB_URL exametra:latest
```

### 4. Verify Deployment
```bash
# Check API health
curl https://your-domain.com/api/v1/health

# Verify database connection

## Support & Maintenance

### Documentation
- See `API_IMPLEMENTATION_GUIDE.md` for endpoint specifications
- See `PHASE_2_COMPLETE.md` for module details
- See `CODE_REVIEW_MODULE_L.md` for technical overview

### Common Issues
1. **Notifications not real-time:** Check WebSocket connection in browser console
2. **Exam lockdown not working:** Verify browser fullscreen API support
3. **Signage not updating:** Check device network connectivity & API authentication
4. **Widget caching stale:** Adjust refreshInterval in dashboard-customizer

### Performance Tuning
- Adjust `refreshInterval` in widget config for resource-constrained servers
- Enable database query caching for frequently accessed views
- Use CDN for signage media and exam resources
