  • Hi Boris,

    Thanks for sharing.

    Can you please help me understanding when start release 4.6 C is supported from SP14 means can we upgrade and migrated with Single step to ECC 6 EHP8 with target database MSSQL with SUM DMO SP17 ,Also seems SAP Note 2161397 is not released to customers,Please any updates when the note will be released



    • Hi Avinash,

      thanks for asking.

      1) Any path that targets a product version based on SAP_BASIS 7.50 has to be on Unicode already (see Why EHP 8 is different). Even though the Unicode conversion can in general be covered by DMO, this is not possible for targeting EHP 8.

      2) SAP Note 2161397 is no longer visible as it is outdated, I will adapt the text. Actual SAP note for DMO with SUM SP 17 is SAP note 2257362.

      Regards, Boris

      • Thanks Boris for the reply.

        So when my system start release 4.6C using SUM SP17 with single step can we go for target database HANA and Product  EHP 6 SAP ERP 6 with combine unicode conversion,upgrade and Migration as in blog it updates SUM SP13 -R/3 as startStart release SAP R/3 4.6C is now supportedCapture.JPG



        • Hi Avinash,

          in general start release 4.6C is supported, and DMO can cover the unicode conversion. Still you have to check all requirements and restrictions listed in the relevant SAP Note (e.g. 2257362 for DMO with SUM SP 17) to know whether your scenario works. As an example, the Unicode conversion of DMO requires a single code page source system.

          Regards, Boris

  • Really nice Boris, I hope you will keep on updating this blog.

    One suggestion, it would be nice to have the release date mentioned as well for the individual SPs as many of the notes related to the SPs are not released for customers anymore (looking at the older versions).


      Thank you for the proposal - I have now listed the status for the actual SUM SPs on top of the table, to show which SUM version is currently supported. Hope that this fits to your proposal.

  • Hi Boris

    We are facing performance issues in the DMO. EU_CLONE_MIG_DT_RUN phase is running for more than 5 days now (with Downtime minimized strategy). It is a combined migration of NUC to UC, Oracle to HANA & EHP6 to EHP7. System details are given below.

    Source system : ERP 6.06, NW 7.31, Non-Unicode, Oracle 12c (OLTP compressed), DB Size 4.5TB, HP rx6600, 4CPU (8 core, 1.6GHz), 64GB RAM, HPUX 11.31 & 2Gb Ethernet.

    SUM Host : SUM is run in AAS, HP rx2600, 2CPU (4 core, 1.6GHz)), 32GB RAM, HPUX 11.31 & 2Gb Ethernet

    Target system : ERP 6.07, NW 7.4, Unicdoe, HANA 2.0, HP BL460c G9, 2 CPU (28 core), 512GB RAM, SLES 12 SP2, 20Gb Ethernet

    SUM version : 1.0 SP 21 (PL5)

    R3load : 749 Patch 301

    No. of R3load processes : 16 (80 to 90% CPU load in SUM host)

    There is no resource bottleneck in CPU, Memory, Disk & Network in Source DB server, SUM host & Target HANA DB.

    Cluster tables like RFBLG, CDCLS etc. are transferred at very slow rate.

    In the export log, the PIPE time is very high compared to DB time as below (one example). DB time : 25668 sec & Pipe time : 41360 sec.

    We are unable to figure out where exactly the issue is as there is no bottleneck in Hardware resource.

    Can you pl help us to isolate the issue?



    • Hi Suresh,

      sorry to read that you are experiencing issues.

      Unfortunately I do not have the capacity to analyze such issues, so hopefully you have meanwhile created an incident.

      Thanks, Boris
