Chapter 1. Supported upgrade paths

Currently, it is possible to perform an in-place upgrade from RHEL 7 to the following target RHEL 8 minor versions:

SAP HANA is validated by SAP for RHEL minor versions, which are getting package updates for longer than 6 months. Therefore, for the SAP HANA hosts, the upgrade paths include only EUS/E4S releases plus the last minor release for a given major release. Upgrading SAP HANA System describes restrictions and detailed steps for upgrading a SAP HANA system.
SAP NetWeaver is validated by SAP for each major RHEL version. The supported in-place upgrade path for this scenario is from RHEL 7.9 to the RHEL 8.x minor version, which is supported by Leapp for non-HANA systems as per the Upgrading from RHEL 7 to RHEL 8 document. Exceptionally for Cloud Providers, the upgrade of SAP NetWaver systems is supported by two latest EUS/E4S releases. Upgrading SAP NetWeaver System describes certain deviations from the default upgrade procedure. For systems on which both SAP HANA and SAP NetWeaver are installed, the SAP HANA restrictions apply.
