Red Hat Network Satellite and Proxy Server Life Cycle


Red Hat provides support and maintenance over stated time periods for the major versions of RHN Satellite and Proxy Server (v. 3, 4, or 5) life cycle. The life cycle allows customers and partners to effectively plan, deploy, and support Red Hat Enterprise Linux.

The life cycle identifies the various levels of maintenance for each major release of RHN Satellite and Proxy Server over a period of five years from the initial release date, which is often referred to as the general availability date.

Software updates to RHN Satellite and Proxy Server are delivered via errata advisories. Errata can be released individually on an as-needed basis or aggregated as a minor release (v. 5.1). Errata may contain security and bug fixes, as well as feature enhancements that have been qualified on the appropriate RHN Satellite and Proxy Server release and architecture. Security errata and urgent bug-fix errata are the only errata released independently of errata advisories.

The RHN Satellite and Proxy Server 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 will 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 RHN Satellite and Proxy Server. For a period of five years following the initial release of the major version of the products, Red Hat will provide errata maintenance for each RHN Satellite and Proxy Server. 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 five-year period is divided into two phases of maintenance.

Support phase Duration Phase details
Production 1 three years Enhancements and maintenance
Production 2 two years Maintenance only: security errata and mission-critical bug fixes

The Production 1 Phase begins on the date that the first major version of the product is released, and ends three years from that date. The Production 2 Phase begins on the end date of the Production 1 Phase and continues for two years.

Scope of Coverage

The following table details the types of software maintenance is performed during each phase of the five-year life cycle:

Life cycle phases
Description Production 1 Production 2
Years after GA 0–3 years 3–5 years
Unlimited-incident technical support1 Yes Yes
Asynchronous security errata Yes Yes
Asynchronous bug-fix errata2 Yes No
Software enhancements Yes No
  1. Full details of support services are provided as part of the subscription agreement.
  2. Red Hat can address catastrophic issues with significant business impact for the customer through a hotfix, as a temporary measure while the bug-fix errata is being created.

Production 1 Phase:

Additional hardware support 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 Production 1 Phase.

Production 2 Phase:

During the Production 2 Phase, qualified security errata of important or critical impact (for a definition, refer to, may be released independently of minor releases.

Urgent-priority bug-fix errata may be released during the production 2 phase at Red Hat's discretion.


Red Hat supports versions of RHN Satellite and Proxy Server, that are still within their five-year life cycle, running as virtualized guests on later versions of Red Hat Enterprise Linux. However to qualify as supported, Red Hat may require that both the guest and host versions have the latest available errata applied.

The Red Hat Enterprise Linux virtualization support matrix provides details on the supported combinations of operating systems, versions, and hardware architectures.

Supporting Software

If supporting software (such as the Oracle embedded database or the underlying operating system) has ended its standard production life cycle (Production Phase 3 for Red Hat Enterprise Linux), customers may be required to upgrade to a more recent version of RHN Satellite and Proxy Server. For example, Red Hat Enterprise Linux Extended Life Phase and/or Extended Lifecycle Support (ELS) are not considered "standard" production life cycle phases and will not be a supported platform for either RHN Satellite or Proxy.

Note: Red Hat will support RHN Satellite and Proxy running on Red Hat Enterprise Linux 4 ELS through December 1, 2012. The scope of this support will only cover Severity 1 issues and to assist upgrades to newer supporting software.

Client Systems

RHN Satellite and Proxy Server is a systems-management platform for extant, supported products. Client systems that have extended beyond their individual support life cycles will not be supported. For example, Red Hat Linux 9 is no longer supported by Red Hat, therefore RHN Satellite Server's ability to manage those systems is also no longer supported. Customers are advised to migrate away from unsupported client platforms promptly. For specific information about supported client systems, please review the RHN Satellite Server Reference Manual.
