SAP S/4HANA conversion and Migration process is significant, and iQuantM does it satisfactorily.
The SAP S/4HANA conversion procedure is divided into roadmap steps. The following actions are involved in the respective roadmap:
- Welcome – The Software Update Manager analyses whether the SAP system is dual-stack, ABAP, or Java standalone. The GUI is assembled based on this analysis’s outcome or results.
- Specify Credentials – In the Specify Credentials roadmap step, the password for the <sapsid>adm user is entered.
- Select Target – Here, the location of the download directory and the stack configuration file is entered.
- Confirm Target – In the Confirm Target roadmap step, the keyword for the update is keyed in.
- Execute Process – The Execute Process roadmap step automatically triggers the next stage of the update process. This roadmap step is broken down into the following roadmap steps:
(i) Initialization – The updated GUI is assembled. According to the result of the previous roadmap steps, either ABAP or Java tab page or both are displayed.
(ii) Extraction – The Software Update Manager extracts the required software using the SAP S/4HANA Migration.
(iii) Configuration – In the Configuration roadmap step, all the information required for the update Procedure is entered. It includes the passwords, the pre-configuration mode, information regarding components, concerning add-ons and Support Packages that need to be encircled more as data regarding the SAP S/4HANA conversion from SAP ECC ERP.
(iv) Checks – The Software Update Manager checks if the system fulfils the necessities for the update procedure (for example, whether or not the specified free area is available).
(v) Pre-processing – The Software Update Manager creates the shadow system in this roadmap step. This shadow system is used for varied update activities, whereas the first system continues to be in production operation. The Software Update Manager builds up the shadow system by cloning parts of the first system. All tables of the SAP NetWeaver Application Server are required as shadow tables to control the shadow system. SAP S/4HANA ERP Implementation is considered mandatory to enhance your business.
The shadow system is employed to modify the ABAP dictionary objects and, therefore, activate recent ABAP dictionary objects that are a part of the update.
Finally, the Software Update Manager performs the shadow import and writes directly into the shadow tables. Triggers indicate modifications to the contents of the first tables. These tables are copied and imported during downtime with the help of the S/4HANA Migration Service in the UK.

(vi) Execution – The switch to the target system takes place in this roadmap step. The Software Update Manager completes the copy import action throughout downtime for all tables with triggers set. The EU_SWITCH section completes the switch to the new system. All tables ready within the shadow system are copied to the target system. The KX_SWITCH_1 part switches the SAP kernel. The PARCONV_UPG phase converts the application table; therefore, TABIM_UPG imports the remaining information. Finally, the XPRAS_UPG part starts the XPRAs required by the system.
(vii) Post Processing – The Software Update Manager saves the log files and prompts the start of certain follow-up activities.
(viii) Finalization – The Software Update Manager removes files and directories that are no longer required and completes the update.
Summary: The Software Update Manager displays a simple feedback form directly in the GUI and prompts the user to send feedback to SAP for technical analysis.
