Chapter 1. Overview
Product Life Cycle Note
Red Hat Enterprise Linux 6 is now in the Maintenance Support 2 phase of the product life cycle. New functionality and new hardware enablement are not planned for availability in this phase. Red Hat Enterprise Linux 6.9 therefore provides a stable release focused on bug fixes. Subsequent updates will be limited to qualified critical security fixes and business-impacting urgent issues. Please refer to Red Hat Enterprise Linux Life Cycle for more information.
In-place Upgrade
As Red Hat Enterprise Linux subscriptions are not tied to a particular release, existing customers can update their Red Hat Enterprise Linux 6 infrastructure to Red Hat Enterprise Linux 7 at any time, free of charge, to take advantage of recent upstream innovations. To simplify the upgrade to Red Hat Enterprise Linux 7, Red Hat provides the Preupgrade Assistant and Red Hat Upgrade Tool. For more information, see Chapter 2, General Updates.
