    Would you have a breakdown of how the host change move works in SUM 1.0 SP21? I am in the middle of a Hana/OS migration of the ERP server. The source system DT export has already finished. However, the destination is only running 1 package while over 300 packages are not completed. In the destination SUM directory, I don’t see anything is missing on the migrate_dt directory compared to the source SUM. However, the import was not run on these packages.

    What drives the destination DT import and how SUM keeps track of what packages to load or not? In the old world of migration monitor, there is a property file that keeps track of the loading status of packages. Is there such a concept in SUM?

    I found the new SUM/DMO a total blackbox. Please help.

      Hi Jonathan,

      Yes, there’s a control for all the package that needs to be imported. I can’t recall as i don’t have the directory/system with me now. What you can do is browse through *dt* or the *log* directories.

      Apart from that, you can analysis the log files on why there’s only 1 package is running, you should get some hints.

       

      Cheers,

      Nicholas Chang

    Hej Nicholas Chang

    this is one of the best SAP Blogs about the tooling for SUM and DMO and the possibilities you can perform. But in the last column about DMO and migration_only there is a wrong information. The SUM 2.0 SP02 with migration_only = 1 in the SAPup_add.par gives you the possibility to work without a stack.xml file, but in this case, only HANA is supported and not Sybase ASE. This is a little bit tricky if you careful read SAPNOTE 2537452 first section.

     

    1. Upgrade & Migrate:

    SAP HANA

    SAP ASE

    MS SQL Server (available on request, see details below)

    IBM Db2 for Linux, UNIX, and Windows (DB6)  (available on request, see details below)

    SAP MaxDB (available on request, see details below)

     

    2. Only Migrate:

    You want to carry out only a migration of your SAP system to the SAP HANA database, but you do not intend to update the SAP system, and hence you do not need to provide a stack.xml file. For more information about this feature, see the topic “Using DMO without System Update” in the “2 Planning” section of the DMO Guide.
