How to use SUM and DMO to perform OS-DB migration with source system on Windows Server 2012


I am in a need to migrate DB from MS SQL 2012 to S/4 HANA and at the same time we need to migrate the OS from Windows 2012 to SUSE LINUX. I found some guides where it is recommended to use SUM and DMO for OS-DB migration but could not found the exacts steps how to use these tools. Is DMO supported to be run on Windows Server 2012 as source system? Please help me with some guide to perform this migration.

    the change of the OS of the ApplicationsServer/PAS is not covered by DMO.

    With DMO you change your AnyDB to HANA(/ASE). Your Applicationserver remains untouched.

    If you want your Applicationserver to run on Linux, you can first do the DMO, and then shutdown the old (Windows) CI and install a new one on Linux.

    Best regards

    • Hi,

      Thanks for the quick response. As per my understandings we have

      DB: MS SQL

      OS: Windows Server 2008

      Standard Hardware: 16Gb RAM

      and we need to achive:

      DB: S/4 HANA


      Now at this stage as per your recommendation if I go for DMO first then I will be needing a standard hardware with 200GB RAM to run HANA DB. So if that is correct approach then I must follow the steps like:

      1) Get a standard hardware with 200GB RAM

      2)Run DMO

      3)Shut down old OS CI

      4) Install LINUX

      If these are the exact steps are to be followed then can you please share any document or detailed guide for steps 3 and 4 ?
