ERP Upgrade to EHP5 with EP ESS, MSS

Hi All,

I just like to confirm there's no dependency if i upgrade my ERP6 system to EHP5 which my EP is running the ESS and MSS?

I've read plenty of notes, esp 1388258 and 1468349. Therefore, i should safe to just upgrade my ERP system instead of ERP along with EP?

    Suggest you to check SAP Note 1324838.

    Incase your Portal system (with ESS and MSS) is connected only to the ERP 6.0 ABAP system (which is to be updated to EhP5), then the NW Portal system is referred to as a Local Sidecar. If this is the case, then you need to update the Netweaver part as well as the ERP Java applications on the Portal to SAP ERP EhP5 levels.

    However, if the Portal having ESS and MSS, is supporting multiple business applications and connects to mutiple backends like SAP SRM, SAP ECC etc - then you could keep the Netweaver part untouched - referring to as the Hub system.

    Check the usage of your Portal system and proceed accordingly.

    As such EHP5 upgrade does no have any dependency on underlying NW version of portal system. But since you are using ESS/MSS and ESS/MSS business packages are installed on portal. You should upgrade your ESS/MSS component to same version as your ERP system.
