== Introduction
|
|
|
|
Red Hat Single Sign-On (RH-SSO) 7.2 is based on the Keycloak project and provides security for your web applications by
|
|
providing Web single sign-on capabilities based on popular standards such as SAML 2.0, OpenID Connect, and OAuth 2.0.
|
|
The Red Hat Single Sign-On Server can act as a SAML or OpenID Connect-based identity provider, mediating with your
|
|
enterprise user directory or third-party SSO provider for identity information and your applications using standards-based
|
|
tokens.
|
|
|
|
RH-SSO provides two operating modes: standalone server or managed domain. The standalone server operating mode represents
|
|
running RH-SSO as a single server instance. The managed domain operating mode allows for the management of multiple
|
|
RH-SSO instances from a single control point. The upgrade process differs depending on which operating mode has been
|
|
implemented. Specific instructions for each mode are provided where applicable.
|
|
|
|
The purpose of this guide is to document the steps that are required to successfully upgrade from
|
|
Red Hat Single Sign-On 7.1 to Red Hat Single Sign-On 7.2.
|
|
|
|
=== About Upgrades
|
|
|
|
==== Major Upgrades
|
|
|
|
A major upgrade or migration is required when RH-SSO is upgraded from one major release to another, for example, from
|
|
Red Hat Single Sign-On 7.2 to Red Hat Single Sign-On 8.0. There may be breaking API changes between major releases
|
|
that could require rewriting parts of applications or server extensions.
|
|
|
|
==== Minor Updates
|
|
|
|
Red Hat Single Sign-On periodically provides point releases, which are minor updates that include bug fixes, security
|
|
fixes, and new features. If you plan to upgrade from one Red Hat Single Sign-On point release to another, for example,
|
|
from Red Hat Single Sign-On 7.1 to Red Hat Single Sign-On 7.2, code changes should not be required for applications or
|
|
custom server extensions as long as no private, unsupported, or tech preview APIs are used.
|
|
|
|
==== Micro Updates
|
|
|
|
Red Hat Single Sign-On 7 also periodically provides micro releases that contain bug and security fixes.
|
|
Micro releases increment the minor release version by the last digit, for example from 7.2.0 to 7.2.1. These release
|
|
do not require migration and should not impact the server configuration files. The patch management system for ZIP
|
|
installations can also rollback the patch and server configuration.
|
|
|
|
A micro release only contains the artifacts that have changed. For example if Red Hat Single Sign-On 7.2.1 contains changes to
|
|
the server and the JavaScript adapter, but not the EAP adapter, only the server and JavaScript adapter are released and require
|
|
updating.
