The different methods for switching to S/4HANA
This method allows you to start again from your existing processes while taking advantage of new possibilities as if it were a new ERP project.
Since the operating principles and organisation remain very similar, it is fairly easy to resume your processes.
Among the major changes to note are the user interface and certain features that SAP has optimized in S/4HANA, including the merger of financial and analytical accounting. It is also an opportunity to replace specific features that were covered by the SAP standard.
In this case, all data must be migrated to a new operating system and servers. For example, data hosted on Windows SQL will be migrated to a Linux server with Hana. The migration tool will then be able to retrieve the information from your original ERP and inject it into the new Hana database. It will transform the data as it would during a traditional upgrade, thereby preserving your history, settings and specific requirements.
Please note: this method requires a more extensive testing phase to verify that the data is working correctly in the new configuration.
In the case of a brownfield migration project, an archiving project may be appropriate (exporting old data to a storage medium to reduce the size of the database). This is particularly important as the size of the database directly impacts the size of the Hana server (memory storage).
Previously, the public cloud was restrictive for businesses. It did not allow for the installation of add-ons or ABAP developments, for example.
With SAP’s RISE solution, there are no longer any limits to the cloud. RISE offers the option of hosting your system by SAP itself, while allowing you to manage all extensions and developments as if the system were on your premises.
And because one advantage rarely comes alone with SAP, the publisher takes care of all the technical aspects and maintenance of your operating system and database. This frees you from all security management, networking, patching, backups, and the resources needed to ensure optimal performance. SAP takes care of all technical tasks and monitoring of the application part of your system. You can even use RISE with your classic ECC ERP for your S/4 Hana migration without having to purchase additional hardware resources locally.
