How Do You Do Data Migration In SAP?

September 29, 2022

According to SAP expert Protera (https://www.protera.com/sap-migration/), one of SAP's most important functions is moving data from one system to another. It is a time-consuming, error-prone process that requires a thorough grasp of SAP, the relevant process and data structure, and a data architect background to find the right dataset, exclude those that won't work, transform the data into the desired format, extract it from the source system, and load it into SAP.

Understanding the strategy for data migration and winning over the project's sponsor and key stakeholders is becoming increasingly important in today's digital world, where data is available electronically from a variety of sources such as an Excel-based legacy system, an old ERP implementation, or a modern implementation of business functions.

In this article, we'll dissect the process of data migration.

Examine Your Current SAP® Infrastructure

Data migration requires an in-depth familiarity with both the source and destination systems. Take the time to learn how much data is being pulled over and what it looks like. Insights gained from this analysis may be used to estimate the cost-benefit of implementing a new system.

Data may have many fields, not all of which will necessarily need to be mapped to the destination system. Likewise, there could be blanks in a source's data that necessitate a lookup into secondary data source to fill in the blanks. Consider what must be brought over, what can be left behind, and what is missing.

In addition to verifying that the transferable data fields are complete, you should examine the data themselves. You should question the necessity of migrating data if there are sparsely populated fields, a large number of missing data pieces, inaccuracies, or other issues.

Auditing the current setup will help you avoid spending time and money on unnecessary upgrades. To top it all off, you'll be able to plan ahead for the new system's requirements and prevent under-provisioning.

Develop a Plan for the Migration

This is the stage where companies choose between a migration strategy and a platform. The technical architecture of the solution and the steps to be taken during the migration need to be mapped out as part of this process.

Careful evaluation of the design, the data to be extracted, and the target system allows for the establishment of timeframes and concerns for a project. By the conclusion of this stage, you should have documentation for every facet of the project.

Safeguarding sensitive information should be a top priority throughout the planning phase. Any critical information should have security built right in.

Clean Your Data Sets

Data cleansing helps reduce the need for expensive new hardware, improves system uptime, and eliminates the need to keep unnecessary data.

Thanks to its superior data analytics and intelligent ERP features, SAP S4/HANA® can quickly and effectively analyse massive databases.

Cleaning your data before moving it to HANA will help your new system run smoothly.

Create and Apply Implementation Standards

To successfully complete a migration, consult with a SAP® professional to establish migration implementation guidelines. The criteria should include migration restrictions, deadlines, technological prerequisites, risks, and disaster recovery plans.

First, check that your current system contains all the necessary components for the migration.

To avoid losing data during the migration, you should back up your database beforehand.

Perform a Live Test Before Total Migration

It is not sufficient to just test the code during the build step. Validating the data migration architecture with live data is essential for ensuring the implementation's robustness and the application's completeness.

Before completely switching over to the new system, a pilot programme or proof of concept can help ensure its viability in a test setting. Proof-of-concept also aids in spotting areas of possible difficulty and compatibility difficulties.

Another perk of doing a pilot before a complete migration is the opportunity to evaluate the new system's functionalities to determine whether they meet the requirements of your organisation.

After a successful proof-of-concept has been implemented, the project plan may be modified to accommodate the live system.

Flipping the Switch

Following the completion of the pilot testing, the implementation can then start in the way that was originally planned.

Audit

As soon as the implementation is live, a method for auditing has to be put in place to check the data for consistency and confirm that the migration was successful.
