When planning
a HANA database upgrade, it’s important to evaluate a few key technical
checkpoints before moving forward. This includes validating SAP application
compatibility with the target database version, understanding the supported N-1
version strategy provided by SAP SE, and confirming whether a direct upgrade
path is available from the current HANA version to the desired target version.
Reviewing these factors early helps minimize upgrade risks, prevents
compatibility issues, and ensures a smoother execution. In this blog, we’ll
walk through these considerations in a practical way to help you plan your
upgrade with confidence.
Please refer SAP Note “1948334 - SAP HANA Database Update
Paths for SAP HANA Maintenance Revisions” which provide use details about SAP HANA maintenance
revisions specifying in detail the supported and unsupported
update paths (Lists of SAP HANA Revisions (HANA 1.0 and HANA 2.0) specifying
in detail the supported and unsupported update paths). For all update
paths not explicitly listed in note, only regular update procedure
applies! The regular update procedure is upgrading from a lower revision
to a higher revision.
* Please Note that SPS05 which is used as
intermediate jump will be out of maintenance in 31.12.2025
Note:
- If you upgrade from a SAP HANA 1
revision prior to revision 69.07, first upgrade your system to SAP
HANA revision 69.07 before upgrading to the target revision.
- The HANA 1 revision numbers 75
through 79, 86 through 89, 98 through 99 and 103 through 109 have been
skipped.
Upgrading
a HANA 1 system to HANA 2:
1) Please
read the guideline for upgrading a HANA 1 system to HANA 2 in SAP Note 2372809.
2) In an MDC landscape, the systemserver doesn’t have separated metadata
space if the binary version is earlier than the maintenance revision
122.04.
If you start your upgrade to HANA 2.0 from a SAP HANA
1system in a multiple-container mode (MDC), you first upgrade the latest
SAP HANA 1 Support Package Stack (SPS) 12 maintenance revision. Please
take care of the unsupported upgrade paths (tables above).
3) Please check the supported Operating Systems of both source and target revisions using 2235581 before upgrading.
