NWDI Upgrade !

Hi All,

We need upgrade our application from SPS18 to SPS20.I am unable to find related notes on SAP service. Can of you help me in finding the actual notes to be analyzed on SAP services.

I am not sure what all documents I am supposed to look into before upgrading application.

Thanks and Regards ,

    Hi Vanita,

    don't worry about basic questions, just shoot if you have any doubts 😉

    As I can see the question is now whether you want to upgrade only the NWDI, or your developed software.

    If you upgrade only the NWDI framework, then there's not much to do as pointed out in my previous post.

    However if you have a track in which you have certain dependent SCs with say SP<X> then you can replace them by

    - copying the new SP<X+1> files into your CMS inbox which you have downloaded from the service marketplace

    - doing a "Restore System State" in both DEV and CONS tabs of the Transport Studio of the CMS webui

    - checking in the new files (Checkin tab in transport studio of CMS)

    - importing them both into DEV and CONS

    (if you want rather a kind of "fresh start" then proceed as described in this blog (and be aware that you'll lose the version history): /people/guenter.schiele/blog/2007/02/12/how-to-migrate-developed-software-components-to-a-new-release-in-nwdi)

    An other important thing is that you need to keep in mind that you are allowed to deploy only and only to such Runtime Systems which are also having the new SP version SP<X+1> in this example. In other words, the SP version of the dependent SCs must be equal to the version of the j2ee engines where you deploy (which you specify for the track on the CMS -- Landscape Configurator -- Runtime System Configuration).

    The perhaps best blog which describes this in a very good way is:

    JDI Software vs. JDI Content


    (also covers what to do with your NWDS version)

    I hope this is clear, let me know if you have further questions.

    Hi Vanita ,

    there are no special considerations that need to be taken into account before doing NWDI upgrade. NWDI is just a framework. Within each track you can develop any version of applications as long as the required build plug-ins content imported are correct for certain development technology. The build plugins are the JDI content which does not depend on the NWDI framework. You can do the NWDI upgrade, this should not have effect on the usability of the existing tracks.

      Hi Ervin,

      Thanks For the reply. I need to give analysis to my team on same. I need to understand it here pretty clear.

      My questions are as bellow. I am not sure about the NWDI server configurations that happen please donu2019t mind for basic questions.

      1.Our NWDI server is SPS16. Upgrading this to SPS20 here means upgrading software components, run time server and what else?

      2. would there be any application side changes that are to be taken care of? Where can I find the application features differing for SPS20?

      3.I have get my NWDS upgraded to SPS20 as well right?

      Thanks !
