Progress with Redwood: Redwood Resources for Oracle Cloud HCM - Go Here
Classic HR Help Desk Migration Resources
You may view the official deprecation announcement on Oracle Help Desk Cloud 25B What's New. Classic HR Help Desk is no longer supported for new implementations of HR Help Desk. Those currently using Classic HR Help Desk in production may continue to do so through 27D. However, only security fixes will be done for the Classic product during this transition period, and no feature enhancements will be added.
All organizations must be migrated to HR Help Desk in the Redwood experience prior to their 28A update. Starting in 28A, the Classic HR Help Desk will be unavailable, and Help Desk in the Redwood Experience will be the only option. This gives a full two years for organizations to migrate to the Redwood Experience for HR Help Desk. Note that other Fusion products or HCM modules may have different Redwood Migration schedules, and this deprecation announcement is only applicable for Classic HR Help Desk.
