Every version of Magento Open Source and Adobe Commerce has a limited lifespan: after release it stays supported for roughly three years, then reaches end of life (EOL). 2.4.9, available since 12 May 2026, will be supported until around May 2029. Knowing where your store sits on this timeline is the first step to avoiding nasty surprises.

Why an EOL version is a risk

Once a version leaves support it no longer receives updates. The concrete consequences are threefold:

• No security patches: vulnerabilities found after EOL stay open, and the store becomes an easy target.
• Module incompatibility: extensions and themes gradually stop being tested against your version, and every new module requires an updated stack.
• PCI compliance at risk: processing payments on unsupported software can breach PCI DSS requirements and jeopardise your relationship with the gateway.

How to find your version's deadline

The rule of thumb is simple: take your version's release date (GA) and add about three years. To identify the version in use you can:

• check the admin panel under Reports → Business Intelligence or the backend footer;
• run bin/magento --version from the command line;
• look at the magento/product-community-edition line in your composer.json.

If your version is more than two years old, it is time to put the upgrade on the roadmap.

Planning the upgrade without surprises

Upgrading to 2.4.9 is not just bumping a number: it changes the underlying stack. You need PHP 8.4/8.5, MySQL 8.4 or MariaDB 11.4 and OpenSearch 3.x. A well-run upgrade follows four phases:

• Module audit: inventory extensions and customisations, check compatibility with the target version and flag what needs replacing.
• Staging environment: replicate production, run the upgrade there and test checkout, payments and critical flows before go-live.
• Budget and timeline: estimate effort based on the number of custom modules; the older the starting version, the more work involved.
• Rollback plan: a full backup and a defined maintenance window, so you can revert safely if something goes wrong.

The benefits of staying on a supported version

Keeping your store on a supported release means timely security patches, compatibility with the latest modules, stronger PCI compliance and better performance thanks to a modern stack. It is an investment that lowers risk and protects revenue.
