Hi guys,



For a couple of days I observed several customers tryng to do System Copy on SAP Hana systems.


Is relevant to highlight that System copy for SAP Hana IS DIFFERENT from normal System copies.



>> For normal system copies you should follow instructions from note:


886102 – System Landscape Copy for SAP NetWeaver BW



>> But, for System copy on SAP Hana systems you need to read and follow steps from note:


1844468 – Homogeneous system copy on SAP HANA



There is also the HANA System Copy Guide:


HANA System Copy Guide



There is also another tool for System copy automation (PCA) that can be used for automate the system copy process:


Post-Copy Automation


System Copy Automation for SAP Business Warehouse System Landscapes (BW PCA)



Best Regards,

Janaina

    • Folks

    just wanted to seek your opinion , guidance and direction… to see which is a better tool for generated reduced volume system copies from / for SAP Business Suite on HANA and BW on HANA.

    TDMS and EPI-USE – do very well when SAP runs on Non-HANA RDBMS…. what about when SAP runs on In-Memory HANA….

    Do you have any experience or can you advise – which is the best tool/ methodology for creating smaller Dev, QA etc from production size HANA systems

      Hi Ajay,

      As you may know it is a big project, and a lot of variants need to be analyzed.

      But I will try to give you a short help:

      1. First step:

      Run the BW sizing (note 1736976), it will generates a forecast of the minimum BW size. If you have EWA (early watch alert) add to the options the anual growth, with that you will be able to know if the investment is for 3, 5 or more years.

      2. After this first step, another required steps is follow the HOUSEKEEPING tasks before the migration, for use less memory. For that you can use archiving, delete old data or delete aggregates…

      Another very helpfull documentation:

      http://scn.sap.com/community/bw-hana/blog/2013/11/13/three-things-to-know-when-migrating-netweaver-bw-on-hana

      3. Make sure you are using the last version of BW SIZING REPORT.

      I hope these steps can help to guide you,

      Regards,

      Janaina
