## Current State (Baseline)
- **Laravel Version**: 5.5.* (Phase 2 Complete)
- **PHP Version**: 7.0+ required (container ready)
- **Database**: MySQL via PDO
- **Branch**: feature/laravel-upgrade

## Completed Upgrades

### ✅ Phase 1: Laravel 5.0 → 5.1 (COMPLETE)
- ✅ Updated composer.json
- ✅ Basic route compatibility verified
- ✅ Middleware working
- ✅ Authentication flow tested

### ✅ Phase 2: Laravel 5.1 → 5.5 LTS (COMPLETE)
- ✅ Updated composer.json (Laravel 5.5.*, Guzzle ^6.3, PHPUnit ~6.0)
- ✅ Created `routes/web.php` with all web routes

- ✅ Expanded `Route::controllers()` to explicit route definitions
- ✅ Updated RouteServiceProvider to use mapWebRoutes() and mapApiRoutes()
- ✅ Updated Exception Handler with Laravel 5.5 patterns
- ⚠️ **Requires PHP 7.0+** - Local test needs Docker container

## Dependencies Audit

### Core Dependencies
- ✅ `laravel/framework`: 5.0.* → Need to upgrade incrementally
- ✅ `webpatser/laravel-uuid`: ^2.0 → Compatible through Laravel 8
- ⚠️ `netshell/paypal`: dev-master → May need replacement (outdated)
- ⚠️ `guzzlehttp/guzzle`: ~5.0 → Need to upgrade to ^7.0
- ✅ `google/recaptcha`: ~1.1 → Still maintained
- ⚠️ `spatie/laravel-analytics`: ^1.4 → Need to upgrade to ^5.0
- ✅ `league/flysystem-sftp`: ^1.0 → Upgrade to ^3.0 for Laravel 9+
- ✅ `aws/aws-sdk-php`: ~3.0 → Compatible

### Custom Middleware Found
- `CheckTeamStorePassword` - Custom team store authentication
- `IsAdmin` - Admin role check
- `IsUser` - Normal user role check
- `isAuthorized` - Custom authorization
- `Cors` - CORS handling

### Custom Code Patterns Detected
- ✅ `app/helpers.php` - Auto-loaded helper functions (minio_url, minio_image_url)
- ✅ Routes in `app/Http/routes.php` (Laravel 5.0 pattern)
- ⚠️ Controllers echoing HTML directly (needs refactoring)
- ⚠️ Boolean stored as strings ("TRUE"/"FALSE" in database)

## Upgrade Path

### Phase 1: Laravel 5.0 → 5.1 (Week 1)

- ⏭️ Update validation rules (needs testing)

### Phase 3: PHP 7.0 → 7.4 & Laravel 5.5 → 6.x (Week 3)
- [ ] Update Dockerfile to PHP 7.4
- [ ] Remove mcrypt dependencies (if any encrypted data)
- [ ] Add string/array helpers package
- [ ] Test file uploads

### Phase 4: Laravel 6.x → 8.x (Week 4)
- [ ] Update factory syntax
- [ ] Test rate limiting
- [ ] Verify queue jobs

### Phase 5: PHP 8.0 & Laravel 8.x → 9.x (Week 5)

- [ ] Test query builder changes

### Phase 6: Laravel 9.x → 10.x (Week 6)

- [ ] Add type declarations where needed
- [ ] Test invokable validation rules

### Phase 7: Laravel 10.x → 11.x (Week 7)

## How to Test the Upgrade

### Quick Test (Docker Required)
```bash
# Run the automated test script
./test-laravel-5.5.sh
```

### Manual Test
```bash
# Build and start container
docker compose -f docker-compose.local.yml up -d --build

# Check Laravel version
docker compose -f docker-compose.local.yml exec app php artisan --version

# List all routes (verify new structure)
docker compose -f docker-compose.local.yml exec app php artisan route:list

# Access the application
# http://localhost:8080
```

### Verify Key Changes
1. **Routes**: Check `routes/web.php` and `routes/api.php` exist
2. **API Prefix**: API routes now automatically prefixed with `/api`
3. **Authentication**: Login routes now use named routes (`login`, `register`)
4. **Middleware**: Web middleware auto-applied to routes/web.php

## Breaking Changes to Watch

### Database
- Boolean fields stored as strings ("TRUE"/"FALSE") - Need migration
- Direct DB facade usage throughout codebase

### Routes
- Controller array syntax in routes will be removed
- Need to update to standard controller@method or invokable

### Middleware
- Middleware signature changes in later versions
- CSRF token handling updates

### Views
- Blade syntax mostly compatible
- PHP in controllers (<?php echo) needs refactoring

### External Services
- PayPal integration (netshell/paypal) may need complete rewrite
- Google Analytics package needs major upgrade
- Screenshot Node.js service should remain compatible

## Rollback Plan
- Keep master branch untouched
- Tag current state: `git tag v5.0-baseline`
- Can revert entire branch if needed
- Parallel testing environment on port 8090

## Testing Checklist (After Each Upgrade)
- [ ] Homepage loads
- [ ] User registration/login works
- [ ] Sports category pages render
- [ ] Designer tool loads
- [ ] Pattern/clipart selection works
- [ ] Cart functionality
- [ ] Team store pages
- [ ] PayPal checkout flow
- [ ] Admin panel access
- [ ] Image serving from MinIO
- [ ] Screenshot generation service
- [ ] File uploads work

## Notes
- Current Composer version 1.x - may need to use `composer self-update --1` during transition
- AWS SDK already at 3.0, compatible with all Laravel versions
- Helper functions (minio_url) should remain compatible
- Fabric.js designer tool is front-end only, won't be affected

## Completed Steps
1. ✅ Created feature branch (`feature/laravel-upgrade`)
2. ✅ Documented current state and dependencies
3. ✅ Created baseline tag (`v5.0-baseline`) for rollback
4. ✅ Updated composer.json for Laravel 5.1
5. ✅ Updated Guzzle 5.0 → 6.0 (required for Laravel 5.1)
6. ⏳ Next: Build container and run composer update
