Tips For a Successful SAP Migration to Cloud
The implementation and management of SAP or any other major ERP system may be a challenging task. However, entering your data and checking that the data loads properly should be easy. Migration to SAP S/4HANA must be well-planned and adhere to quality standards.
S/4HANA offers capabilities beyond those of standard database tools. The platform services stores data in memory and may be used locally or in the Azure cloud. It helps companies in many ways, like speeding up operations, getting more out of data, and streamlining IT. In order to avoid wasting time, money, and other resources, it is crucial to follow the recommended switch process according to Protera.
The data obtained from this exercise should help estimate the time, money, and outside aid needed to complete the S/4HANA conversion successfully.
After deciding to migrate to S/4HANA, the first step is creating a migration strategy. A smooth transition can only be achieved by planning and carrying out a systematic migration process that is grounded on industry best practices explained below;
Opt for simple solutions
Learn about the existing data assets, the systems they are housed in, and how they fit into the proposed model. Analyze the information’s profile to determine if there are any early advantages that may be helpful to the company’s main drivers.
If one of your goals is to double your client base, you should use all available clean data infrastructure to strengthen your current connections. This will ensure your customers do not suffer.
Look for a Migrating Partner Who is an Expert in Selectivity
There is more than one viable option for your migration strategy. When deciding which aspects of Brownfield and Greenfield to exploit in your S/4HANA migration, you may find that migration associates specializing in SAP transformation projects provide mix-and-match techniques.
For example, you may retain the current hardware installations and software upgrades that come with a Brownfield strategy. However, you may avoid the drawbacks of a Greenfield one, such as the loss of updated corporate processes and policies.
Estimate the Amount of Data that Will be Required for the Transfer
To shine, you will need to bring over data from your existing ERP system for S/4HANA’s sophisticated applications and analytics. Master data, configuration data, and, most importantly, historical data all fall under this category. This background information is the driving force behind the platform’s predictive and precise modeling capabilities.
It’s imperative to immediately calculate how much historical data would need to be migrated to benefit from the system’s analytics features. Similarly, the financial implications of HANA’s growing memory needs must be included in that decision.
Pick the Aspects That Will be Simplified, Enhanced, and Left Unchanged
How you decide what to keep the same and what to change will depend on the application’s specifics and the areas of the company it touches. Adopting SAP’s standardized process can be helpful in some fields like finance.
Some activities, such as billing, may be highly individualized to the point that any change would risk a crucial aspect of the company’s operations. It’s helpful to draw a map of every module, component, and unique process that will be impacted. This will help you to decide what should be streamlined, improved, or preserved in light of the changing environment.
Come Up with a Plan for Rollout that Will Ease Migration Difficulties
A greenfield or brownfield strategy is the most common approach by users when implementing a HANA migration.
Greenfield refers to a complete transition from the legacy platform to the updated one, including a full system reset, and the introduction of updated enterprise procedures and settings. In this method, the company’s existing proprietary code is discarded in favor of the newly developed design.
When compared to Greenfield, a brownfield is more of a technological improvement. Brownfield is a move-and-drop upgrade instead of a rewrite that replaces the existing code with a new setup.
However, the specifics of the transfer process will vary from one organization to another. Although Greenfield and Brownfield’s methods are the most common, they are not without their share of problems. With Greenfield’s top-down approach, new business procedures must be carefully developed and implemented.
A brownfield is an all-purpose approach that transfers everything to the new system, including irrelevant data, objects, and customizations. This eliminates enterprises’ flexibility in determining which business processes to modernize, which legacy components to decommission, and which new HANA capabilities to exploit.
