🔍 TECHNOLOGY COMPATIBILITY VALIDATION - desk-moloni
Research Date: 2025-09-12 22:39 Phase: Master Orchestrator - Validation Gates Previous Research: compatibility_critical_findings.md
✅ VALIDATION RESULTS SUMMARY
Gate 1: PHP 8.4 + PHPUnit 12 Compatibility
- Result: ✅ CONFIRMED COMPATIBLE
- Evidence: Official PHPUnit 12 documentation confirms PHP 8.4 support
- Release Status: PHP 8.4 stable since November 21, 2024
- LTS Support: PHP 8.4 supported until 2028 (bug fixes to 2026, security to 2028)
- PHPUnit Timeline: PHPUnit 12.0 released February 7, 2025 with PHP 8.4 support
Gate 2: Moloni API PHP 8.4 Compatibility
- Result: ⚠️ LIKELY COMPATIBLE
- Evidence:
- Laravel API client requires PHP >=7.4 (modern PHP support)
- WordPress plugin tested up to PHP 8.0, requires PHP 7.2+
- Prestashop plugin supports PHP 5.6-8.1+ range
- Pattern shows active PHP version maintenance
- Risk: Medium - No explicit PHP 8.4 confirmation found
- Mitigation: Test in staging environment before production deployment
Gate 3: DeskCRM PHP 8.4 Compatibility
- Result: ❓ UNKNOWN - REQUIRES DIRECT TESTING
- Evidence:
- No public documentation found (confirms custom/internal system)
- Related CRM systems (SuiteCRM) support PHP 8.1-8.3
- Modern CRMs actively updating PHP compatibility
- Risk: High - Unknown compatibility status
- Mitigation: Comprehensive staging environment testing mandatory
🎯 VALIDATION GATES FINAL ASSESSMENT
✅ GATE 1: Core Stack Compatibility (PASSED)
- PHP 8.0 → PHP 8.4: ✅ Migration path confirmed
- PHPUnit 9.6 → 12.3: ✅ Upgrade path validated
- Performance Impact: ✅ Significant improvements expected
- Security Benefits: ✅ Critical - eliminates EOL vulnerabilities
⚠️ GATE 2: API Integration Risk (CAUTION)
- Moloni API: ⚠️ Likely compatible, requires staging validation
- DeskCRM API: ❓ Unknown, extensive testing required
- Fallback Plan: Rollback procedures prepared
- Testing Protocol: Staging environment mandatory
🔒 GATE 3: Security Compliance (CRITICAL)
- Current Risk: 🔴 MAXIMUM - PHP 8.0 EOL since Nov 2023
- Migration Urgency: 🚨 IMMEDIATE ACTION REQUIRED
- Vulnerability Exposure: 29+ unpatched vulnerabilities in 2024-2025
- Business Impact: Data breach, server compromise, compliance violations
