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 8:
Operating system:
- SAP HANA is installed with a version that 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.
Additional Information:
SAP HANA hosts must meet all of the following criteria:
- Running on x86_64 architecture that is certified by the hardware partner or CCSP for SAP HANA on the source and target OS versions.
- Running on physical infrastructure or in a virtual environment.
- Using the Red Hat Enterprise Linux for SAP Solutions subscription.
- Not using Red Hat HA Solutions for SAP HANA.
SAP NetWeaver hosts must meet the following criteria:
- Using the Red Hat Enterprise Linux for SAP Solutions or Red Hat Enterprise Linux for SAP Applications subscription
- High Availability: If you are using the High Availability add-on, follow the Recommended Practices for Applying Software Updates to a RHEL High Availability or Resilient Storage Cluster KBA.
Please also refer to Chapter 2 and particularly the known limitations mentioned there in the Upgrading from RHEL 7 to RHEL 8 document, as these also apply to the upgrade procedure for SAP HANA and SAP NetWeaver hosts.
