Outcome Overview

Once all Features and testing are complete, OpenShift will default to RHEL10 and continue to support RHEL9 for two releases.

This outcome is a blocker for OpenShift's October 2026 release.

Success Criteria

1. Customers can enable a feature that allows them to upgrade to the next major RHEL release (RHEL10) separate from upgrading to the next OpenShift major release.
2. An affirmative "ready" signal from RHCOS indicating that all blocking bugs related to RHEL 10 have been resolved.
3. An affirmative "ready" signal from TRT and propagated through OpenShift engineering teams, indicating that component readiness signal is stable for both RHEL9 and RHEL10.
4. A timeline for the support of both versions have been communicated to customers, partners, and stakeholders.

Expected Results (what, how, when)

A default installation of OpenShift will include the latest RHEL release.

Upgrade to the latest RHEL can be administered by customers separately from upgrading to the latest OpenShift release.

RHEL 9 support can be deprecated and no longer a dependency of OpenShift features.
