Supported Releases and Upgrade Paths for ZDO

This section provides information on the releases and upgrade paths supported by the Zero Downtime Option (ZDO).

With start release SAP S/4HANA® 2020, Zero Downtime Option is generally available. In particular, from SAP S/4HANA 2020 onwards, ZDO can be used as a standard feature. The general availability of ZDO for SAP S/4HANA also includes updates of feature or support package stacks within SAP S/4HANA 2020.

SAP Note 2707731 is the comprehensive entry point to get all relevant information before starting a ZDO project.

Supported Products and Add-ons

Besides SAP S/4HANA 2020 (or higher), also SAP S/4HANA Foundation 2020 (or higher) is supported by ZDO. Note that the product SAP S/4HANA Foundation is not allowed to be used as standalone, but only as a foundation in combination with a defined list of add-on product versions. Further details can be found in the release information SAP Notes, for example:

  • SAP Note 3306766 - SAP S/4HANA FOUNDATION 2023: Release Information Note

  • SAP Note 3143630 - SAP S/4HANA FOUNDATION 2022: Release Information Note

SAP S/4HANA supports add-ons from different vendors such as SAP or third parties:

  • Standard add-ons delivered by SAP for SAP S/4HANA
  • Add-ons delivered by SAP Innovative Business Solution (former SAP Custom Development)
  • Partner add-ons

For details, see SAP Note 2214409 - SAP S/4HANA: Compatible Add-Ons. However, not all add-ons available for SAP S/4HANA implicitly are equipped with zero-downtime maintenance capability. Hence, Software Update Manager is equipped with an automated check if ZDO can be used for the system. The selection of ZDO in the Software Update Manager user interface, as well as the check, is described in a later lesson.

Hint

Always check the latest version of SAP Note 2707731 that lists the SAP and partner add-on products not supported by ZDO. If ZDO is not possible because of add-on products in the system, potentially a custom-specific project can be started. The process for custom-specific projects is described in the same SAP Note.
