Hello, I’ll carefully migrate the application architecture, refactor deprecated CI2 logic into CI4 standards (routing, controllers, models, libraries, helpers, sessions, database handling, etc.), and test the full system to ensure stability, performance, and clean maintainable code throughout the upgrade process. I have 10+ years of experience in PHP and CodeIgniter development, including legacy CI2/CI3 to CI4 migrations, framework modernization, database refactoring, and production-safe upgrade workflows. Please share the current project size, PHP version, custom modules/libraries, and repository access so I can evaluate the migration scope and provide a clear upgrade plan and timeline. thank you Regards Gaurav Garg

Hello, I can help you migrate your existing CodeIgniter 2.2.x application to the latest CodeIgniter 4 version with a clean, secure, and maintainable architecture. I have strong experience working with legacy PHP applications and modernizing them into updated frameworks while preserving existing business logic and minimizing downtime. Since CI2 and CI4 have major architectural differences, I will carefully handle the migration process to ensure stability and compatibility. My migration approach includes: • Analyzing the existing CI 2.2.x project structure and dependencies • Migrating controllers, models, libraries, helpers, and routes to CI4 standards • Refactoring deprecated functions and outdated PHP code • Updating database connectivity and query handling • Improving security, validation, and application performance • Testing all modules and fixing compatibility issues • Ensuring clean, scalable, and maintainable code structure If required, I can also assist with: • PHP version upgrades • API modernization • Authentication/session migration • Server deployment and environment setup • Performance optimization Before starting, I would like to review the current codebase and understand the project size, third-party integrations, and custom modules involved so I can estimate the timeline accurately. Looking forward to discussing the project further. Best regards, Ali

Hi there, You’re not just moving a CodeIgniter app, you’re protecting a working system while modernizing the framework underneath it. That usually means the real risk is hidden in legacy CI 2.2.x patterns, custom libraries, and PHP compatibility gaps, and that’s exactly where I can help. I’ve migrated and upgraded PHP applications across older CI versions, refactoring controllers, models, helpers, session handling, routing, and deprecated syntax so the new CI 4.2.x structure stays clean and maintainable. I’ll review the existing codebase, map the legacy architecture to CI4 conventions, and handle the migration carefully so functionality remains consistent while improving security and long-term support. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Do you already have a list of modules, third-party libraries, or custom helpers that must be preserved during the CI 2.2.x to 4.2.x migration? My focus will be on clarity, compatibility, and a smooth transition with minimal disruption. Thanks, Asad
