OS Upgrade on Longleaf: RHEL9 -> RHEL10
Last updated:July 8, 2026
Longleaf default behavior currently remains as R9.
Due to significant changes in RHEL 10 affecting Open OnDemand, the RHEL 10 upgrade for Longleaf is on hold, and not yet scheduled to move forward. RHEL 10 makes a major shift to Wayland as the primary/only native windowing system for the desktop.
This page will be updated when we have more information about Longleaf migration to RHEL 10.
