Upgrading drmhope Hospital Management Software to CakePHP 5.0.1

## Introduction This document specifies the requirements for upgrading the drmhope Hospital Management Software from its current version ( we use Cakephp PHP version 4.1.14) to the latest version of CakePHP, which is 5.0.1. The upgrade aims to enhance performance, security, and maintainability of the software. ## Project Scope The scope of this project is to upgrade the existing CakePHP framework used in drmhope to version 5.0.1, ensuring that all functionalities are retained and optimized for the new framework version. ### Objectives - Upgrade CakePHP to version 5.0.1. - Ensure compatibility of existing features with the new CakePHP version. - Optimize performance and security. ## Detailed Requirements ### 1. Environment Preparation - Set up a development environment that mirrors the current production environment. - Ensure backup of the current system, including all files and databases. ### 2. CakePHP Upgrade - Install CakePHP 5.0.1 on the development environment. - Update `[login to view URL]` and other configuration files as required. - Resolve any dependencies that may arise due to the new version. ### 3. Code Refactoring and Compatibility - Refactor existing PHP code to be compatible with PHP 8.3, as CakePHP 5.0.1 requires PHP 7.2 or newer. - Update and optimize existing CakePHP code to align with the new framework's best practices and features. - Remove deprecated functions and features from the old version of CakePHP. ### 4. Feature Verification and Enhancement - Ensure that all existing functionalities (e.g., patient management, appointment scheduling, etc.) are retained and fully operational. - Explore new features and enhancements provided by CakePHP 5.0.1 to improve existing functionalities. ### 5. Testing - Conduct comprehensive testing including: - Unit testing for individual components. - Integration testing to ensure all parts of the application work together seamlessly. - Performance testing to verify that the application performs well under the expected load. - Security testing to identify and fix potential vulnerabilities. ### 6. Documentation - Update technical documentation to reflect changes in the system architecture and codebase. - Document any new features or changes in the workflow. ### 7. Training and Support - Provide necessary training materials or sessions for the development and maintenance teams. - Plan for ongoing support during the initial phase post-upgrade. ### 8. Deployment - Plan for a phased deployment starting with a staging environment. - Implement rollback strategies in case of unexpected issues during deployment. ### 9. Post-Deployment Monitoring - Monitor system performance and stability post-deployment. - Quickly address any issues or bugs that arise. ## Deliverables - Upgraded source code compatible with CakePHP 5.0.1. - Updated and expanded documentation. - Test cases and reports. - Deployment plan and rollback strategy. ## Timeline and Budget - Proposed timeline for completion: 10 days - Budget: To be negotiated based on the scope and complexity of the work.
