Red Hat Enterprise MRG Life Cycle

Overview

Red Hat has established fixed life cycles for Red Hat Enterprise MRG, which allows customers and partners to plan their resources, certifications, and implementations.

To enable customer maintenance cycles, each Red Hat Enterprise MRG is supported via errata service packs. These service packs contain security, bug fixes, and enhancement errata that have been qualified on the appropriate Red Hat Enterprise MRG release. Security errata will be the only errata released independently of service packs. To minimize the impact of security errata, Red Hat has a policy of backporting security fixes whenever possible.

Details

For a period of up to seven years from initial release (general availability), Red Hat will provide errata maintenance for Red Hat Enterprise MRG. To promote and retain the high standard of stability inherent in the Red Hat enterprise products, the maintenance period is divided into two phases. The first phase lasts two years. The second phase lasts from the start of year three to either the end of year seven or the end-of-life date of the parent Red Hat Enterprise Linux, whichever occurs first.

Timeline

This table summarizes the two support phases after general availability (GA) of a major release.

Support phase Years after GA Support provided
Phase 1 Years 0–2 Full support: see Scope of Coverage
Phase 2 Years 2-7 or the retirement date of the parent Red Hat Enterprise Linux, whichever occurs first Maintenance only: at a minimum, qualified security errata of Critical impact will be released.

Phase 1: Full support

Start date: general availability

End date: two years from general availability date

Description: during the full support phase, support will be provided for both production and development use according to the Scope of Coverage for Red Hat Enterprise MRG. During the full support phase, all available and qualified errata will be applied via service packs (or as required in the case of security-level errata). Updated ISO images will only be provided during the full support phase.

Phase 2: Maintenance

Start date: two years from general availability (end of full support)

End date: five years from end of full support (seven years from general availability), or the end-of-life date of the parent Red Hat Enterprise Linux, whichever occurs first.

Description: during the maintenance phase, Red Hat will provide support for production use only, according to the published Scope of Coverage. During this phase, at a minimum, qualified security errata of Critical impact (definition at access.redhat.com/site/security/updates/classification/) will be released.
