Chapter 1. Red Hat Decision Manager versioning

Red Hat Decision Manager versions are designated with a numerical Major.Minor.Patch format, such as 7.0.1. In this example, the major release is 7.x.x, the minor release is 7.0.x, and the patch release is 7.0.1. Major releases often require data migration, while minor release upgrades and patch updates are typically managed with upgrade and update tools provided with the Red Hat Decision Manager release artifacts.

The following are the general types of releases for Red Hat Decision Manager:

Major release migrations

Major releases of Red Hat Decision Manager include substantial enhancements, security updates, bug fixes, and possibly redesigned features and functions. Data migration may be required when an application is moved from one major release to another major release, such as from Red Hat JBoss BRMS 6.4 to Red Hat Decision Manager 7.0. Automated migration tools are often provided with new major versions of Red Hat Decision Manager to facilitate migration, but some manual effort is occasionally required for certain data and configurations. The supported migration paths are specified in product announcements and documentation.

For example migration instructions, see Migrating from Red Hat BRMS 6.4 to Red Hat Decision Manager 7.0.

Minor release upgrades

Minor releases of Red Hat Decision Manager include enhancements, security updates, and bug fixes. Data migration is not typically required when an application is upgraded to the next minor release, such as from Red Hat Decision Manager 7.0 to Red Hat Decision Manager 7.1. Automated upgrade tools are often provided with new minor versions of Red Hat Decision Manager to facilitate upgrading.

Minor release upgrades currently do not apply to Red Hat Decision Manager 7.0.

Patch updates
Patch updates of Red Hat Decision Manager typically include the latest security updates and bug fixes. Scheduled patch updates contain all previously released patch updates for that minor version of the product, so you do not need to apply each patch update incrementally in order to apply the latest update. For example, you can update Red Hat Decision Manager 7.0.0 or 7.0.1 to Red Hat Decision Manager 7.0.2. However, for optimal Red Hat Decision Manager performance, you should apply product updates as they become available. Occasionally, unscheduled patch updates may be released outside the normal update cycle of the existing product. These may include security or other updates provided by Red Hat Global Support Services (GSS) to fix specific issues, and may not be cumulative updates. Automated patch tools are often provided with patch releases of Red Hat Decision Manager to facilitate updating.

To keep your Red Hat Decision Manager distribution current with the latest enhancements and fixes, apply new product releases and updates to Red Hat Decision Manager as they become available in the Red Hat Customer Portal. Consider also enabling product notifications in the Red Hat Customer Portal.
