The key benefits of our version adoption policy are:

Types of Releases in SAP Integration Suite, Advanced Event Mesh

SAP offers two release types for advanced event mesh: Production and Preview. Both are generally available releases available for Kubernetes-based deployments.

Production releases are generally available software intended for production use and offer the following:

• High-severity and security fixes are available within 30 days of availability of an industry-accepted remedy.

• Solace releases qualified security errata and selected urgent bug fixes as they become available. The qualified security errata includes critical and high Common Vulnerability and Exposures (CVEs), and critical and important Red Hat Security Advisories (RHSAs).

Preview releases are intended for new feature introduction and integration. Preview releases provide a subset of the features to give you a preview and an indication of what is available in the next Production release. They have the following limitations when compared to Production releases:

• SAP offers only technical support for Preview releases (six months after the release date of the software event broker).

• No maintenance loads are provided. SAP any addresses critical bugs or security issues identified in a Preview release in the next Production release.

• You can only create new event broker service with Preview releases. Upgrades to the Preview release from existing event broker service are not possible or supported.

• The upgrade path for a Preview release event broker service is to upgrade to the subsequent Production release.

Support Phases in SAP Integration Suite, Advanced Event Mesh

Each Production release has a full support phase and a technical support phase. The technical support phase begins after the full support ends. The technical support phase provides adequate time to upgrade existing event broker services to the most recent Production release (that supports upgrades).

Because Preview releases are intended for feature introduction and integration rather than production purposes, they offer only a technical support phase. If you want to upgrade a Preview release, you can upgrade only to a newer Production release.

The phases of support are summarized in the following table:

Phase of Support	Time Frame	What's Included in the Support Phase
Full Support for Production releases	One year from the date of the release of the Production software event broker from Solace.	High-severity and security fixes are available within 30 days of availability of an industry-accepted remedy. Qualified security errata and selected urgent bug fixes are released as they become available. The qualified security errata includes critical and high Common Vulnerability and Exposures (CVEs) , and critical and important Red Hat Security Advisories (RHSAs). The software event broker versions in this phase allow creation of new event broker services.
Technical Support for Production releases	Six months from the date that the full support phase ends.	Software updates and security updates are no longer provided. New event broker services cannot be created with software event broker versions in this phase. SAP upgrades your event broker services during an upgrade slot that you choose SAP continues to answer technical questions during this time.
Technical Support for Preview releases	Six months from the release date.	Software updates and security updates are not provided. Upgrade to this release are not supported. Only new service creation is supported. SAP answers technical questions during this time.
