The Best Methods for Migrating S/4 HANA

Ensure that your HANA landscape is the proper size.
When creating a technical project plan, the most crucial stage is to size the SAP HANA infrastructure with extreme caution. Under sizing may lead to needless delays that raise operating expenses, while oversizing may result in excess capacity and overburdened hardware.

Choose the appropriate migration strategy on the appropriate platform.

There are numerous platforms and approaches accessible, and one can select one based on funds, budgets, and business needs. Businesses can opt to run SAP HANA on-site or in the cloud.

Data purification

Database migration would go more quickly if data sizes were smaller. Retaining only the data that is absolutely necessary to carry out the migration process efficiently is advised. Either the fields can be modified to reflect information in accordance with new standard blueprints, or the data in master data sets can be standardized based on the information.

Raising the bar for implementation

At this stage, stay clear of detours and adhere to the strategy and high standard. Being productive in all essential tasks—from preparation to migration—is the secret to an efficient migration. The prerequisites for professional migration must be understood by the migration team.

carrying out a POC

It is a good idea to test the migration through a Proof of Concept (PoC) process before committing to the full movement. You will be able to approve the movement procedure using the PoC.
The Best Approach for S/4 HANA Migration Greenfield
For the greenfield method, a fresh SAP S/4HANA setup is required. As you have to start from scratch, this project can be laborious and time-consuming, particularly when it comes to change management. Making full use of S/4HANA’s capabilities while simplifying and redefining business processes is the advantage of this strategy.

BLUEFIELD®

The BLUEFIELDTM strategy, which adaptably blends the advantages of Greenfield and Brownfield, is conceivably the most popular model. Ultimately, large businesses must preserve some critical customizations and solutions while overhauling some of their procedures and processes.
Through the use of this automated software-centric transformation methodology, many of the risks involved in the transition to SAP S/4HANA are reduced. As you clean up and move your data to the new system, you can make incremental changes to some of your system’s components while keeping others functional.

Brownfield

The brownfield path is an alternative that has all the ramifications of the greenfield strategy. This is SAP’s proposal for current clients running SAP ECC who wish to switch to S/4HANA while maintaining their investment in the current framework.
With system conversion, the entire system and business process will be moved to a new S/4HANA platform. This strategy might offer a better option if you do not want to alter how your business process operates.
