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.
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 (BYOS) instances on all public clouds that use Red Hat Subscription Manager (RHSM) for a RHEL subscription.
SAP HANA and Netweaver requirements:
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 use the High Availability add-on, see the Recommended Practices for Applying Software Updates to a RHEL High Availability or Resilient Storage Cluster Knowledgebase article.
