Question 1

What happens when Oracle Solaris reaches end of life?

Accepted Answer

When Oracle Solaris reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 7 Oracle Solaris versions are already EOL. The latest supported version is Oracle Solaris 11.4, maintained until November 1, 2031. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Oracle Solaris 11.4 still supported?

Accepted Answer

Yes. Oracle Solaris 11.4 is actively supported until November 1, 2031. It receives security patches and bug fixes. Check the version table above for the full list of supported Oracle Solaris releases and their exact end-of-life dates.

Question 3

Is it safe to use Oracle Solaris after end of life?

Accepted Answer

No. Running Oracle Solaris 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 Oracle Solaris release.

Question 4

How to upgrade from Oracle Solaris 11.3 to Oracle Solaris 11.x?

Accepted Answer

To upgrade Oracle Solaris from 11.3 to 11.4: (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 Oracle Solaris LTS version?

Accepted Answer

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

Question 6

How long does Oracle Solaris support each version?

Accepted Answer

On average, Oracle Solaris supports each release for approximately 121 months (~10.1 years).  The exact EOL date for each version is listed in the table above.
