DMOVE2S4 and Homogeneous option for SUM DMO

Jens Gleichmann • Okt. 25, 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
von Jens Gleichmann 05 Nov., 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 Okt., 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.

RISE with SAP: Roles & Responsibilities
von Jens Gleichmann 24 Mai, 2024
For every possible RISE with SAP customer it is essential to know the difference of the status quo system construct (on-prem self managed / hosted or managed by a MSP) and the RISE offering with a lot of excluded tasks or tasks with additional costs. If you don't need this tasks, it might be a perfect solution, but our experience is that most customers need some of the services with extra costs.

SUM tooling with target HANA
von Jens Gleichmann 18 März, 2024
Numerous IT projects such as S/4HANA projects or HANA migrations will go live over the Easter weekend. Mostly this tasks will be controlled by the SAP provided SUM tool. The SUM is responsible for the techn. migration/conversion part of the data. Over the past years it become very stable and as long as you face no new issues nearly every technical oriented employee at SAP basis team can successfully migrate also bigger systems. In former times you needed a migrateur with certification which is no longer required. As long as all data could be migrated and the system is up and running the project was successful. But what does the result look like? Is it configured according to the best recommendation and experience? Is it running optimized and tuned?No, this is where the problem begins for most companies. The definition of the project milestone is not orienting on KPIs. It is simply based on the last dialog of the SUM tool, which states that the downtime has ended and all tasks have been executed successfully.
