Quick Answer

We upgrade your OpenCart extensions to be compatible with newer OpenCart versions. Ensure your extensions work smoothly after platform upgrades.

Keep Your Extensions Compatible

When you upgrade OpenCart to a newer version, your existing extensions often need updates too. OpenCart major versions change database schemas, file structures, and coding patterns, which means extensions built for one version may not work on another. Our extension upgrade service ensures your critical extensions continue functioning after platform upgrades.

What We Do

  • Compatibility Assessment: We analyze each extension against the target OpenCart version to identify incompatibilities.
  • Code Migration: We update extension code to use the correct APIs, database methods, and template patterns for the target version.
  • Template Conversion: For 3.x to 4.x upgrades, we convert templates from the old format to Twig templates.
  • Database Updates: We modify database schemas if the extension uses tables affected by the version change.
  • Testing: Comprehensive testing of all extension features on the target OpenCart version.
  • Documentation: Updated documentation reflecting any changes in configuration or usage.

Common Upgrade Scenarios

  • Upgrading 2.x OCMOD extensions to 3.x compatibility.
  • Converting 3.x extensions with PHP templates to 4.x with Twig templates.
  • Updating PHP 7.x code to PHP 8.x compatibility.
  • Migrating from deprecated OpenCart APIs to current equivalents.

Pricing

Extension upgrade pricing depends on extension complexity. Simple modules with minimal database interaction start at lower rates, while complex extensions with multiple controllers, models, and database tables require more work. We provide a detailed quote after reviewing each extension.

Frequently Asked Questions

Can any OpenCart extension be upgraded?
Most extensions can be upgraded if we have access to the source code. Some very old or poorly coded extensions may be better replaced with modern alternatives. We assess each extension and recommend the most cost-effective approach.
How long does an extension upgrade take?
Simple extensions typically take 1-3 days. Complex extensions with extensive database interaction, multiple templates, and API integrations may take 1-2 weeks. We provide time estimates during the assessment phase.
Will the extension settings be preserved?
Yes, we preserve all existing settings and data when upgrading extensions. Database tables and configuration values are migrated to maintain your current setup. You should not need to reconfigure the extension after the upgrade.
Do you provide support after the upgrade?
Every extension upgrade includes 30 days of support. If any issues arise related to the upgrade, we fix them at no additional charge during this period.
Can you upgrade third-party extensions I purchased elsewhere?
Yes, we can upgrade extensions regardless of where they were purchased, as long as you have a valid license and we can access the source code. We respect the original developer intellectual property throughout the process.
