SAP Windows Server Upgrade

Hi Everyone;


I have SAP ERP System 6.0 EHP5 with Oracle 11.g

My plan is to upgrade from Windows server 2008 R2 to Windows 2016

My question is should I just stop SAP and Oracle then do the normal upgrade process of my windows server or there are others steps that I need to take into consideration.

    Hello Amal,

    You have to consult the SAP Product Availability Matrix (PAM) to check whether your intended OS / DB combination is supported for your SAP release.

    As far as I can tell, ECC 6.0 EhP5 on Oracle 11.2 is only supported up to Windwos Server 2012. Also, standard support for this combination has ended 31.12.2018.

    Best regards

    Frank

    • Hi Frank;

      Thank you :) after checking the matrix I got the idea. Yes with oracle 11.2 I can only upgrade to windows server 2012.

    Hello Amal,

    your in-place upgrade would result in an unsupported DB/OS combination. Therefore, after a successful in-place upgrade to Windows 2016 you have to upgrade the database release, so it will be supported.

    Same with the SAP kernel.

    Please also keep in mind to un-install antivirus solutions BEFORE you run setup.exe of Windows Server 2016. With an active antivirus scanner, setup.exe will not continue to upgrade the OS.

    You didn't wrote if your Windows 2008 R2 runs virtualized on VMware or Hyper-V or on a physical box? If running on physical hardware the in-place upgrade must be tested and afterwards drivers etc. must be upgraded.

    In an case: Test this!!!

    Best regards,

    • Dear Karl;


      Thank you so much, and yes you are right as I checked the availability matrix just as Frank suggested, and found out that for my SAP EHP 6.0 EHP5 Kernel 7.22 Unicode for database ORACLE 11.2 64 bit I can only upgrade to windows server 2012 or windows server 2012 R2.

      So what I will do is that:

      1- Upgrade from windows server 2008 R2 to windows server 2012 R2

      2- Once step one is done I will upgrade from ORACLE 11.2 64 to ORACLE 12.2 64

      3- If needed upgrade from windows server 2012 R2 to windows server 2016 LTSB 64BIT

    Hello Amal,

    sounds like a good plan! But do no forget to test this! :-)

    Based on my experience with in-place upgrade they work very good if

    1. Windows is running already virtualized (VMware, Hyper-V, XEN, KVM …)

    2. no incompatible filter drivers are installed (like antivirus … host intrusion stuff …)

    Keep in mind that in-place upgrade of Windows Failover Cluster node is only possible if you use Windows 2016 or higher.

    Best regards,

    Kalle
