In an SAP implementation process, data migration is a necessary procedure. Since the process is prone to errors, finding professionals with extensive data architecture and SAP systems knowledge is essential in respective companies. The process involves finding the correct dataset, extracting it from the source system, and loading it into the new SAP system.
However, this process has a few setbacks; for example, in some cases, the data in the source system could be in an unusable state. Therefore, transformation is necessary. When adopting SAP Migration Cockpit, it would be helpful to identify the model that ideally suits your company’s system and business requirements. This article will discuss the necessary procedures for migrating to an SAP S/4HANA system.
What Are The Steps For Data Migration SAP?
Procedure
Preparation Phase
In the initial stages of the data migration process, deciding the approach by which legacy data will migrate from the legacy system to the new system is essential. These approaches include the big-bang method, also known as rapid data migration, and the incremental approach.
You should also review the SAP S/4HANA migration process requirements to ensure they are key solutions to your problems. The migration process is becoming more manageable daily due to the many migration templates appearing on the market. The last bit of this phase is coming up with a project schedule and time frame for completing it.
Conduct Data Extraction
The second phase aims to convert and group the master data in the legacy system into forms relevant to the SAP basis. Relevancy rules group data from legacy systems, so those fitting the criteria are prepared for the next step. The downloaded templates will guide you on the format in which the extracted legacy data should be presented after extraction.
Generally, this activity is to prepare source data files for migration; this is done by filling the migration template fields with information like product names with legacy data from the old legacy systems. At the end of this phase, the legacy data has been extracted from the legacy system and is ready for SAP data migration in the next step.
Integrate and Extend Phase
The most critical processes of the migration procedure are in this phase. Steps performed include; upload, data validation, data conversion, and data import. In the first upload step, the system checks the reliability of the data uploaded. Similarly, the confirmation is to validate if the migration template has the correct data feed into it.
However, the extracted data may sometimes not be in the desired form. Therefore, converting them into suitable forms is essential to ensure a successful data migration process. The last part of this phase is examining the quality and integrity of the master data. This process is essential when dealing with transactional data; therefore, skip it at your own risk.
Migration Phase and System Environments
This phase involves three simple but necessary procedures, which include;
Initial Test Migration System
This first procedure ensures that the SAP Hana new system software covers all the business parameters. It also helps acquaint you with the overall migration process and migration templates. Sometimes, you can use a small sample of legacy data and run it through the system, testing the site contents for efficiency and reliability.
Perform Migration into the Test System
This procedure analyzes the overall SAP migration process with a fair amount of data. It allows data architects to adjust the migration environment to ensure the success of the migration process.
Additionally, content integrity should be high to meet the required standard. Therefore, you can proceed to the next step after verifying that the data has been loaded into the updated system and meets the required configurations or requirements.
Final Migration
After updating all the data in the migration template from your SAP migration system, arrange extensions according to business preferences. For your data to be up to date when using the incremental approach, migrate your data at the last stage of the migration process. You can load your data into the redesigned production system successfully. SAP tools make the SAP Hana migration process more manageable if you follow the LSMW steps one by one.
