Chapter 2. Planning an upgrade
An in-place upgrade is the recommended and supported way to upgrade your SAP HANA system to the next major version of RHEL.
You should consider the following before upgrading to RHEL 9:
Operating system:
- SAP HANA is installed with a version which is supported on both the source and target RHEL minor versions.
- SAP HANA is installed using the default installation path of /hana/shared.
Public clouds:
- The in-place upgrade is supported for on-demand Pay-As-You-Go (PAYG) instances on Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform with Red Hat Update Infrastructure (RHUI). The in-place upgrade is also supported for Bring Your Own Subscription instances on all public clouds that use Red Hat Subscription Manager (RHSM) for a RHEL subscription.
