Question 1

What happens when Chef Infra Server reaches end of life?

Accepted Answer

When Chef Infra Server reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 3 Chef Infra Server versions are already EOL. The latest supported version is Chef Infra Server 15. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Chef Infra Server 15 still supported?

Accepted Answer

Yes. Chef Infra Server 15 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported Chef Infra Server releases and their exact end-of-life dates.

Question 3

Is it safe to use Chef Infra Server after end of life?

Accepted Answer

No. Running Chef Infra Server after EOL is not safe for production systems. Once a version reaches end of life, newly discovered CVEs are published publicly but never patched — leaving your systems permanently exposed. The only safe path is upgrading to an actively supported Chef Infra Server release.

Question 4

How to upgrade from Chef Infra Server 13 to Chef Infra Server 15.x?

Accepted Answer

To upgrade Chef Infra Server from 13 to 15: (1) review the official migration guide for breaking changes, (2) test your application against the new version in a staging environment, (3) update dependencies that have version constraints, (4) run your full test suite, (5) deploy with a rollback plan. The earlier you start, the more time you have to resolve compatibility issues before EOL.

Question 5

When is the next Chef Infra Server LTS version?

Accepted Answer

Not all Chef Infra Server releases have a designated LTS status. Check the version table above — LTS releases are marked with an "LTS" badge. Refer to the official Chef Infra Server release policy for information on upcoming long-term support versions.

Question 6

How long does Chef Infra Server support each version?

Accepted Answer

On average, Chef Infra Server supports each release for approximately 57 months (~4.8 years).  The exact EOL date for each version is listed in the table above.
