DMOVE2S4 and Homogeneous option for SUM DMO

Jens Gleichmann • 25. Oktober 2023

Spotlight on for Homogeneous option for DMO and DMOVE2S4 aka “DMO move to SAP S/4HANA (on hyperscaler)”

Homogeneous option for DMO (with system move)

DMO used to be heterogeneous (change of DB). Now you can use DMO with system move (also on-prem to target on-prem) to migrate and convert ECC on HANA to S/4 or just update/upgrade S/4 and move it to another location like other DC or other instance in one step.

SAP BW or SAP BW/4HANA systems are not supported
target “SAP ERP on SAP HANA” is not supported
only *HANA to S/4: Only target product SAP S/4HANA is supported
can also be used on prem (e.g. ERP 6.0 on HANA to S/4)
doDMO and doC are supported for homogeneous DMO since SUM 2.0 SP18
no rename of SID in the procedure possible (separate step afterwards needed)
possibility to retain the source after SUM procedure
R3load file mode is used

DMOVE2S4 aka “DMO move to SAP S/4HANA (on hyperscaler)”

The DMOVE2S4 is just to move and convert to the "cloud" in one step. This includes also anyDB source systems and downtime-optimization techniques (doDMO and doC). SAP illustrates it as cloud but, you can also use another DC or another hoster.

Approach is not a SUM option => more a combination of SUM features and options
alternative to “DMO with system move”
plain-DMO
Only target product SAP S/4HANA is supported
Approach works for source systems on anyDB as well as on SAP HANA DB
R3load pipe mode is used, not file mode
prerequiste: Latency < 20 ms between source and target
prerequiste: Bandwidth > 400 MBit/s
SUM runs a latency check
doDMO and doC are supported for homogeneous DMO since SUM 2.0 SP18
no rename of SID in the procedure possible (separate step afterwards needed)
no official possibility to retain the source after SUM procedure
ASCS which is not running with a AAS (=standalone) cannot be moved as standalone within the procedure => it will run within one AAS

=> Due to the fact that the R3load pipeline mode is used this option is faster compared to the "normal" DMO system move approach.

Performance degradation after upgrade to SPS07

Ongoing HEX performance issues with SPS07

von Jens Gleichmann • 5. November 2024

With SPS06 and even stronger in SPS07 the HEX engine was pushed to be used more often. This results on the one hand side in easy scenario to perfect results with lower memory and CPU consumption ending up in faster response times. But in scenarios with FAE (for all entries) together with FDA (fast data access), it can result in bad performance. After some customers upgraded their first systems to SPS07 I recommended to wait for Rev. 73/74. But some started early with Rev. 71/72 and we had to troubleshoot many statement. If you have similar performance issues after the upgrade to SPS07 feel free to contact us! Our current recommendation is to use Rev. 74 with some workarounds. The performance degradation is extreme in systems like EWM and BW with high analytical workload.

HANA OS maintenance

von Jens Gleichmann • 29. Oktober 2024

Please notice that when you want to run HANA 2.0 SPS07, you need defined OS levels. As you can see RHEL7 and SLES12 are not certified for SPS07. The SPS07 release of HANA is the basis for the S/4HANA release 2023 which is my recommended go-to release for the next years. Keep in mind that you have to go to SPS07 when you are running SPS06 because it will run out of maintenance end of 2023.
