Red Hat Update Infrastructure Life Cycle
Red Hat provides support and maintenance over stated time periods for the major versions of Red Hat Update Infrastructure (v. 1 or 2) life cycle. The life cycle allows customers and partners to effectively plan, deploy, and support Red Hat Update Infrastructure.
The life cycle identifies the various levels of maintenance for each major release of Red Hat Update Infrastructure over a period of three to five years from the initial release date, which is often referred to as the general availability date.
Software updates to Red Hat Update Infrastructure are delivered via errata advisories. Errata can be released individually on an as-needed basis or aggregated as a minor release or maintenance (v. 1.2 or v. 2.0.2). Errata may contain security and bug fixes, as well as feature enhancements that have been qualified on the appropriate Red Hat Update Infrastructure release and architecture. Security errata and urgent bug-fix errata are the only errata released independently of errata advisories.
The Red Hat Update Infrastructure life cycle is designed to reduce the level of change within each major release over time, increasing predictability and decreasing maintenance costs. All released errata remain accessible to active subscribers across the entire life cycle. Red Hat publishes this life cycle in an effort to provide as much transparency as possible and may make exceptions from these policies as conflicts may arise.
Support will be provided for use according to the published Scope of Coverage for Red Hat Update Infrastructure. Red Hat will provide errata maintenance for each Red Hat Update Infrastructure deployment. To encourage the rapid adoption of new enterprise hardware and software while keeping the high standard of stability inherent in the Red Hat enterprise products, the life cycle is divided into two phases of maintenance.
|Support phase||Duration||Phase details|
|Full Support||Three years||Enhancements and maintenance|
|Maintenance Support||As Defined in the chart below||Maintenance only: security errata and urgent-priority bug fixes|
The Full Support phase begins on the date that the first major version of the product is released and ends three years from that date. The Maintenance Support phase begins on the end date of the Full Support phase and continues as defined in the chart below. Please note that Red Hat Update Infrastructure major version 1 will only contain a Full Support support phase.
Scope of Coverage
The following table details the types of software maintenance performed during each phase of the five-year life cycle:
Life Cycle Phases

|Years after GA1||0–3 years||As Defined in the chart below|
|Unlimited-incident technical support2||Yes||Yes|
|Asynchronous security errata||Yes||Yes|
|Asynchronous bug-fix errata3||Yes||No|
- Version 1 is only supported during Full Support; there will be no Maintenance Support. Version 2 follows the five-year life cycle.

Full Support Phase:
Additional enhancements will be provided at the discretion of Red Hat via product releases. All available and qualified errata will be applied to the products via errata advisories or on an as-needed basis for required for Security-level errata. Updated ISO images will only be provided during the Full Support phase.
