PHP extranet site update to latest verson

This project seeks a skilled PHP developer to perform an update of an extranet site to the latest version. The selected freelancer will be required to download the existing site codebase to a local testing environment. Once downloaded, the freelancer should thoroughly update the site to the newest version, ensuring all features and functionality remain intact through the upgrade process. Comprehensive version control and documentation is paramount, so the freelancer must commit and push all code changes to a Git repository with detailed comments on all updates and fixes. Testing of the updated site locally and committing to version control is required before the changes can be promoted to the live production site. Excellent communication and documentation practices are essential to meet the client's needs for transparency throughout the process. The ideal candidate will have extensive experience upgrading PHP-based websites and environments, strong skills with version control systems like Git, and the ability to conduct updates with minimal disruption to live site operation. Attention to detail and reliability are crucial as the client relies on this extranet site for key business functions.
