Generate a code review checklist for microservices migration converting legacy monolithic ERP modules to containerized Spring Boot services

Legacy ERP Module Files *

Migration Complexity Level * Choose complexity level Low - Single bounded context with minimal external dependencies Medium - 2-3 bounded contexts with API dependencies (<5 integration points) High - Complex module with database coupling and 5-10 integration points Critical - Legacy monolith core with shared database/table dependencies Enterprise - Multi-module system with legacy TP monitors or mainframe integration

Target Business Domain * Select primary domain Order Management Inventory Control Financial Accounting Human Resources Customer Relationship Management Supply Chain Management Production Planning Procurement Warehouse Management Billing and Invoicing Asset Management Compliance Reporting

Regulatory Compliance Requirements * Select applicable regulations SOX - Sarbanes-Oxley Act Financial Reporting GDPR - General Data Protection Regulation HIPAA - Health Insurance Portability and Accountability Act PCI DSS - Payment Card Industry Data Security Standard SOC 2 Type II Security Controls ISO 27001 Information Security Management NIST Cybersecurity Framework FDA 21 CFR Part 11 Electronic Records Basel III Banking Regulations Custom Internal Compliance Framework Non-regulated Internal Systems

Performance SLAs *

Deployment Strategy * Choose strategy Blue-Green Deployment with instant cutover Canary Release with 10% traffic migration Feature Flags with gradual rollout Strangler Fig Pattern with legacy coexistence Database-per-service pattern with eventual consistency Shared database pattern with anti-corruption layer Event sourcing with CQRS architecture Saga pattern for distributed transactions

Integration Points *

Security Architecture Level * Select security level Public API - Basic authentication required Internal Service - mTLS with service mesh Sensitive - Client certificates + OAuth2 Highly Sensitive - Zero trust with mutual TLS Legacy Integration - VPN + reverse proxy Multi-tenant - JWT + tenant isolation Regulated Data - Encryption at rest + transit Financial Systems - Hardware security module required

Code Quality Gates * Choose quality standards SonarQube Quality Gate - 80% test coverage required OWASP Top 10 Security Scan passing CodeClimate maintainability A grade minimum PMD ruleset compliance (Critical and High) Branch coverage > 85% with mutation testing Cyclomatic complexity < 10 per method Docker image scanning - No critical vulnerabilities License compliance through FOSSA scanning Performance benchmarks in CI/CD pipeline Multi-stage Dockerfile with distroless images

Operational Readiness Requirements *

Testing Scope * Choose testing coverage Unit tests with 80% coverage minimum Integration tests with test containers Contract tests via Pact with consumer-driven End-to-end tests in staging environment Performance tests with JMeter/Gatling Chaos engineering with Chaos Monkey Contractual SLA validation tests Legacy data migration validation tests Security penetration testing User acceptance testing with business users
