What Is SAP’s Recommended Migration Strategy?


SAP users deliberating all type migration process often wonder what SAP’s official recommendation.

For those getting to keep their investments in their current ECC, system conversion is that the preferred approach. S/4HANA System Conversion solution provides the knowledge and ease you would like to start out your journey to S/4HANA migration, including valuable insights and an in-depth report.


Steps to a Successful SAP S/4HANA Migration

Greenfield


If your decision is to perform a newest implementation via the greenfield approach, there’s a whole methodology called SAP Activate that explains each step required to try.
Discover: The first step is to identify the value of your business and then develop the road-map and strategy to be used in the implementation of the project.
Prepare: In this phase, you initiate the project and begin performing on your final project plans also as preparing your team. Choosing the proper people for your team is important to make sure the project will run optimally.
Explore: SAP S/4HANA offers an honest range of solutions for your business, especially for a newest implementation. In this phase, the scope evaluation process is going to be performed, and Fit/Gap analysis are often adopted—instead of traditional blueprint requirements—in order to make sure a more efficient and faster implementation.
Realize: This phase focuses on the proper process of the business requirements that are defined within the previous phase. These include system configuration settings, integration scenarios, and data migration.
Deploy: The production environment is done in this phase. When its ready, cutover activities are going to be performed and business operations are moved to the new system.

Brownfield & Landscape Transformation


If you decide to undertake a system conversion or landscape transformation, there is a sequence that you simply got to follow to form sure a smooth deliverable. The process is split into two phases: preparation and realization.


Preparation Phase


System Requirements & Planning: This assessment should be conducted to analyse the existing system and then define the best possible solution to execute the migration.
Conversion Pre-Check: A compatibility check of any add-ons or business functions that are active within the current system is required to make sure they will technically be converted into S/4HANA. SAP has provided the Simplification Item Check to spot the mandatory steps before converting your system.
Custom Code Migration: In this step will check your custom code against S/4HANA compatibility. This is essential, especially if there are enhancements in your current system.


Realization Phase

System Installation: After the preparation phase, you’ll start the conversion to SAP S/4HANA. This step includes database migration and data conversion.
Follow-On Activities: After all the technical conversion, all relevant customized settings must be migrated.
Data Consistency Check (especially for financial data): Since SAP S/4HANA collects all relevant components from Financial Accounting (FI) and Controlling (CO) into one data pool, called the Universal Journal, it’s imperative that you simply perform reconciliation between your accounting components. In this way, the info is often merged correctly into the Universal Journal.

Some other valuable points to consider while SAP S/4 HANA migration


Custom code transitioning:
While migrating on HANA, it’s required to spend a while in brooding about custom code remediation. Understand that custom code won’t be optimized by default while completing the migration process. By not doing custom code remediation, you’re risking performance problems and functionality issues.
You can use tools like custom code cockpit and clone finder, which can assist you in understanding the custom code.
Go for cross-functional project teams:
While conducting the migration process, it’s required to deal with multiple aspects like OS, network and storage and management.
