I will upgrade fix or customize your legacy oscommerce PHP store
Munaza
About this gig
Is your osCommerce store running on outdated PHP, showing errors, or becoming risky to maintain?
I am a senior PHP developer with 15+ years of experience repairing and modernizing legacy e-commerce systems. I work carefully with existing stores where customer data, custom modules, checkout logic, and business operations cannot simply be replaced.
I can help with:
- PHP and MySQL version compatibility
- osCommerce errors, warnings, and broken features
- Custom modules and feature development
- Checkout, payment, shipping, and API integrations
- Store migration and hosting changes
- Performance, database, and security improvements
- Responsive fixes and front-end updates
- Safe modernization without an unnecessary full rebuild
Before making changes, I review the current system, identify the real cause, and choose the lowest-risk solution. Backups and staging are strongly recommended for upgrade or migration work.
Please message me before ordering. Share your osCommerce version, PHP/MySQL version, hosting details, error messages, and required outcome so I can recommend the correct package.

FAQ
Can you work with heavily customized osCommerce stores?
Yes. I first review the custom modules, overrides, database structure, PHP version, and integrations so changes do not break existing business workflows.
Can you upgrade an old store to a newer PHP or MySQL version?
Yes. I can identify compatibility problems, update deprecated code and database calls, test critical workflows, and recommend a staged upgrade plan.
Do you provide a backup before making changes?
A verified backup is strongly recommended. I can work with an existing backup or include backup and staging setup when it is agreed in the order scope.
Can you migrate my osCommerce store to new hosting?
Yes. I can move files and databases, update configuration, and test URLs, email, checkout, and integrations while reducing downtime where possible.
Should I contact you before ordering?
Yes. Legacy stores vary widely. Please send the store URL, osCommerce version, PHP/MySQL versions, error details, and the result you need.
