Understanding Magento Version Upgrades

Minor Version Upgrades

Updates within the same major version (e.g., 2.4.5 to 2.4.6) include bug fixes, security patches, and incremental improvements. These generally maintain backward compatibility but still need testing.

Major Version Upgrades

Updates between major versions (e.g., 2.3 to 2.4) include significant changes that may break customisations and extensions. These require more extensive planning and testing.

Security Patch Updates

Adobe releases security patches between versions. These targeted updates address specific vulnerabilities and should be applied promptly.

Our Version Upgrade Process

  1. Version Assessment – Document your current version and identify the optimal target version
  2. Compatibility Check – Review all customisations and extensions for version compatibility
  3. Upgrade Path – Determine whether direct upgrade is possible or intermediate versions needed
  4. Development Upgrade – Perform upgrade in isolated environment first
  5. Extension Updates – Update or replace extensions as needed for compatibility
  6. Custom Code Updates – Modify customisations to work with new version
  7. Testing – Comprehensive testing of all functionality
  8. Production Deployment – Safe deployment with rollback capability

Why Version Upgrades Matter

Staying current with Magento versions is important for several reasons:

  • Security – Older versions stop receiving security patches
  • Performance – Newer versions include optimisations
  • Features – Access to new functionality
  • Support – Adobe phases out support for older versions
  • Compatibility – Extensions increasingly require newer versions
  • PHP Requirements – Older Magento needs older PHP versions reaching end-of-life

Common Version Upgrade Challenges

Deprecated Features

Magento deprecates features between versions. Code relying on deprecated functionality needs updating.

Extension Incompatibility

Not all extension vendors keep pace with Magento versions. Some extensions need replacing.

Database Migrations

Schema changes between versions require careful data migration.

Theme Updates

Frontend themes may need updates to work with new Magento versions.

Frequently Asked Questions

Which Magento version should we upgrade to?

Generally the latest stable version. We assess your specific situation and recommend the best target version based on your requirements and compatibility factors.

Can we skip versions in the upgrade?

Sometimes. It depends on your starting version and the changes between versions. We determine the optimal path during assessment.

How long do version upgrades take?

Minor upgrades may take 1-2 weeks. Major upgrades with many customisations can take 4-8 weeks. We provide realistic timelines after assessment.

What about our customisations?

We review and update all customisations to work with the new version. Functionality is preserved while ensuring compatibility.

Will there be downtime?

We minimise downtime by working in staging first. Production cutover typically requires a maintenance window of a few hours.
