Lifecycle policy4


AIX technology levels are supported for how to, usage, and problem identification for the entire life of the release, but have a limited support window for new fixes. If a fix is required, a customer may be required to move up to a current technology level to receive the interim fix. Please see the IBM AIX Operating System Service Strategy Details and Best Practices document for a detailed discussion on this topic including dates. In general, beginning with AIX 5L™ V5.2, the AIX life cycle is being extended to a minimum 10-year life cycle. A minimum of six years of usage and fix support will be available to clients under the standard SWMA. Following that period, three years of extended support will be available under an optional, separately priced service extension. After the extended support period, IBM will provide client self-assist service on the Internet. Clients will have access to online product documentation, technical support data, and online fix downloads for one year after the extended support period.
