    HiShankar,

    Yes, you can upgrade 4.7 to ecc6 directly. Please follow the links, good documentation is avilable.

    http://service.sap.com/upgrade

    www.thespot4sap.com/upgrade_guide_v2.pdf

    It's difficult to say H/Wconfig (for ECC6) in one word, you need to consider your existing loads and expecting loads you can caliculate initial sizing with quick sizer

    Regards,

    Hari.

    PS: Points are welcome.

    Hi,

    1.- Yes you can upgrade from 4.7 to ECC 6 but you need to check requisites first like Oracle in 10.2.0.2, Java 1.4.2_12, etc

    2.- You must use the guide under service.sap.com, follow carfully this guide and you won't have much trouble, recomendation: use the lattest R3trans, TP and db libraries.

    3.- If you are going to change hardware I strongly recommend to move operating system and database manager to 64 bits. I have the experience with two upgrades from 4.5 and from 4.7 to ECC 6 and in both cases the systems were really slow due the 32 bits (Windows) after the upgrade so we then migrate the OS to 64 bits in new hardware. I used the quick sizer and it was wrong, vendor did a sizing and it was wrong also, both sizing told that the systems were OK to upgrade to ECC 6 but in reallity both systems were extremely slow after the upgrade.

    We did Going Live technical upgrade from SAP but although we follow the suggestions the systems were too slow so the users complained all day long.

    In general if windows 2003 64 bits use something like 8 Gb of RAM, 2 Dual Core proccessors enough disks to have different RAIDS so Data, Redologs and Arch logs are not togheter in the same physical drives.

      Hi,

      >>can you please guide the Steps for upgrading 4.7 to ECC6

      1) Plug your brains on

      2) Read all the documentation you have been guided to

      3) Understand all this documentation

      4) Practice the upgrade several times on systems which are database copies of the production system

      5) Upgrade the production system

      6) Relax and appreciate the feeling of the success of your first SAP upgrade

      7) Update your CV

      8) Answer to questions about upgrades on SDN forums

      I don't think the steps can be more precise in a forum thread. 😉

      Good luck !

      Olivier
