EP 5.0 SP4 - best version to upgrade

Hello Experts,

Our client is using EP5.0 SP4 with SAP4.6C version and IIS server, but present requirement is to upgrade this version or to support maximum number of users(around 20 k users more, so in total it has to support around 35 k users).

Could anybody please let me know how we would proceed with with, I mean I have to understand myself answers for the follwoing questions.

1) What is the best version and system configuration to support around 30 to 35 k users.

2) What about the current SAP version. ( SAP4.6c), do we need to upgrade this as well ? or can we use the same SAP version and only upgrade EP to someother version. If so, what will be the impacts on EP and SAP.

Also, please send some links regarding the same.

Thanks in advance

    Hi Purandhar,

    Upgrade is to get the enhanced functionality of the application. To support maximum no of users, we need to increase the hardware size based on the requirement.

    Best way is to upgrade the hardware and application also.

    we have to use the quick sizer tool for calculating the hardware size.

    fundamentally you are talking about a major upgrade here. Because of the version of EP5.0 you are on - it is not trivial.

    Technically you dont have to upgrade your backend systems but it is highly recommended for scalability and stability purposes. There may be licence / support considerations to think about - cant really comment because sometimes it depends on your relationship with SAP. If you ask SAP they will blind you with the complete upgrade - you can however safely move to EP6.0 whilst maintaining your backend systems as is.

    To be honest id recommend you move as quickly as possible to a Netweaver platform across the board. Unfortunately for portal you only really have 2 options - (1) the upgrade path which is patch to EP5.0 SP6 then migrate to NW2004 (essentially to at least EP6.0 SP9) and then optionally on to EP7.0.

    (2) Depending on the amount of iviews and content you have to move - you might consider starting again - it may take less time than the upgrade path !!!!! You can always transfer your content out into the filesystem (make it an FSDB).

    Not trivial and needs careful planning. You have to bear in mind the change from EP5 to EP6 is a massive shift architecturally - you may find some of your portal content no longer works at all. EP6.0 to EP7.0 is a MUCH smaller issue since the bulk of the architecture is the same.

    Hi!

    As Haydn already said, you will have to migrate your Portal to the Netweaver Platform, which is a defined migration process. Nonetheless as LOTS of things change it might really be advisable to start from scratch on the new release, in which case it's probably better to start directly on Netweaver7.

    It could be an option to take a parallel approach - migrate the current system to get an idea of the results (current system is not destroyed during this migration process) and install a clean sandbox in parallel where you can get an idea of the effort required to recreate all the functionality from scratch.

    For the R/3 I'd say 4.6C is not a bad release. This definitely is an independent project and it's probably safer and easier to first take care of the portal and think of the backend upgrade as an independent step, which is not of the same urgency.

    Regards,
