The Client

One of the largest school management software providers in the Baltic region, serving 5,000+ organizations through a SaaS platform for managing student records, admissions, attendance, grading, and communication.

Challenges Addressed

• Migrating mission-critical legacy PHP backend without data loss
• Ensuring near-zero downtime during migration
• Integrating Laravel with coexisting Java modules
• Enhancing system scalability, performance, and security
• Lack of legacy system documentation requiring reverse engineering

Collaboration in Action

Cubet, as an official Laravel Partner, led the end-to-end migration strategy—from discovery to deployment. The engagement covered codebase rebuild, phased database migration, and blue-green deployment using modular Laravel architecture, ensuring business continuity and scalability.

Technologies Deployed

Backend: Laravel 11 (PHP 8.x) with Eloquent ORM
Legacy Migration: PHP monolith + Java modules
Database: MySQL (migrated), Redis, Laravel Horizon
DevOps & Infrastructure: Docker, AWS ECS, Blue-Green Deployment, GitHub Actions CI/CD
Integrations: APIs for Java modules, ERP/HRMS, external school ERP tools

Innovative Feature

Executed a blue-green deployment strategy for near-zero downtime. Used modular Laravel architecture, Horizon for queue management, and Scout for faster search—creating a scalable backend with 30% faster response times and future CI/CD readiness.

Value Delivered

• Completed migration in 12 weeks
• Less than 30 minutes of downtime during switchover
• 30% improvement in API response times
• Future-proof SaaS architecture with multi-tenant support
