SAP S/4 HANA Migration

Migrate to SAP S/4 HANA to help you tackle changing market dynamics and streamline business goals. Accely provides SAP migration services for all enterprises.

Let’s Discuss

What is S/4 HANA Cloud?

The Software-as-a-Service (SaaS) version of the SAP S/4HANA ERP system is the SAP S/4HANA Cloud. It is a suite of integrated business applications which allow company resources to be planned according to the company’s needs. This suite is also available with SAP S/4HANA Cloud as cloud ERP applications.

The SAP S/4HANA Cloud was first introduced in February 2017 as the’ intelligent ERP system of the modern generation.’ The provider offers businesses a solution that does not rely on their own resources, such as internal hardware, databases, and IT expertise, with an ERP framework as a cloud-based software version.

Users can connect their departments and functional areas digitally, digitize their business processes, and thus more quickly respond to new trends in growth.

The SAP S/4HANA Cloud runs on the SAP HANA in-memory database. This high-performance analysis program, which was only available in conjunction with different hardware prior to the SAP cloud solution, uses artificial intelligence, among other things, to analyze vast volumes of data.

The development and integration platform’s in-memory technology enables users to access their data quicker and “in real time” to speed up processes.

Why Migrate to S/4 HANA Cloud?

By giving you access to advances in data analytics technology, such as embedded real-time analytics, SAP S/4HANA can help your company realize its true potential. By using SAP Fiori, it will also provide you with the new user experience. You also get better response times and better results from HANA.

As a company offering consulting services for SAP S/4HANA, we understand that a large number of SAP applications will only be available on SAP S/4HANA in the future. This will cause issues for businesses that are still using SAP legacy systems. With cloud applications such as SAP performance factors, HANA incorporates the conventional ERP framework.

Another benefit of HANA is that an organization can open the doors to emerging innovative technologies such as IoT, Big Data and blockchain by combining them with SAP Leonardo.

Another strong justification you need to switch to SAP S/4HANA is that if you do not move rapidly towards the new system, you will be left with an obsolete system by 2025. The earlier you make the transition, the faster you will start gaining from the new system.

Smooth transition from SAP ECC to intelligent ERP with SAP S/4 HANA Migration to save time, tackle market dynamics, and smooth business goals.

Advantage of S/4 HANA Cloud Migration

Thanks to HANA’s super-fast analytics engine, embedded reporting and streamlined processes, you can easily gain real-time business insights for better decision-making, optimized processes and better services.

Run faster in a more agile manner, thanks to the simpler data model of SAP S/4HANA and the highly intuitive user interface of SAP Fiori.

Accelerate innovation to simplify and reinvent the business, as traditional ERP with CRM, EWM, transport management, etc. and cloud applications, such as SAP Customer Experience, SAP SuccessFactors, Concur, SAP Fieldglass and SAP Ariba, are combined with the central HANA center.

It can also be easily expanded with SAP Leonardo, SAP’s digital innovation infrastructure that opens the door to IoT, big data, blockchain, and more. Only on SAP S/4HANA will a growing number of new SAP applications be available.

Sizing for S/4 HANA Cloud

SAP HANA Sizing is a specific task that is essentially carried out to estimate the SAP HANA system’s hardware specifications, including major components such as RAM, CPU, and hard disk. Memory is the main component in scale and the secondary component is the CPU.

So, once we have learned about the five-step ITERATIVE SIZING method, with the aid of a practical example, it is easy to gain knowledge about SAP S/4HANA Sizing. In this tutorial, if we deploy the on-premise SAP Fiori front-end for SAP S/4HANA as well as the back-end server, we will discuss how to size the SAP HANA landscape.

The question, however, is why do you need size for both front-end and back-end servers?

SAPS/4HANA, which implements the SAP Fiori user interface in native mode, is the response to the question. This SAP Fiori is browser-based and accesses back-end info.

On the Front-end Note

The SAP Fiori user interface is hosted on the front-end SAP Fiori server, which transforms OData service calls to remote feature calls and back-end servers. It is also the responsibility of the front-end server to manage additional services in order to run SAP Fiori Launchpad smoothly. Personalizing user accounts and login features are included in the activities.

On the Back-end Note

The back-end focuses primarily on the integration of OData services, which is an important step in enabling the SAP Fiori framework to access the back-end data and to verify the business logic and conduct different activities.

Best Practices for S/4 HANA Migration

Get the right size for your HANA landscape

The most important step is the very careful sizing of the SAP HANA infrastructure when designing a technical project plan. Oversizing can result in excess capacity and overloaded hardware, while under sizing may result in unnecessary delays that will increase operating costs.

On the right platform, choose the correct migration strategy

Various platforms and methodologies are available that can be chosen based on business requirements, capital, and budgets. On-premise or in the cloud, businesses can choose to run SAP HANA.

Data cleaning

Reducing data size would allow the relocation of databases to take less time. It is recommended that only essential data be retained in order to effectively conduct migration. Either the data in master data sets can be standardized based on the information or the fields can be changed for information according to new standard blueprints.

Set elevated expectations for implementation

At this point, maintain distance from alternative routes and comply with the high and strategic norm. The key to effective migration is to be productive in all fundamental tasks, from preparation to migration. The migration team must be aware of the requirements for professional migration.

Doing a POC

Testing the migration in a Proof of Concept (PoC) process before you pull the trigger on the complete movement is a good idea. The PoC will allow you to approve the procedure for movement.

Most Effective Methodology for S/4 HANA Migration


A new implementation of SAP S/4HANA is needed for the greenfield approach. This can be a tiresome and time-consuming project, especially on the side of change management, because you have to start everything from scratch. The benefit of this approach is that you can redefine and simplify business processes and make full use of the capabilities of S/4HANA.


Possibly the most widely used model is the BLUEFIELDTM approach that flexibly combines the strengths of Greenfield and Brownfield. Large organizations need to overhaul some of their workflows and processes at the end of the day, while retaining some important customizations and solutions as well.

You minimize a lot of the risks associated with making the jump to SAP S/4HANA with this automated software centric transformation approach. You can selectively overhaul some elements of your system, while still retaining those that function at the same time that you clean and transfer your data to the new system.


There is an alternate path with all the implications of the greenfield approach: the brownfield path. For existing customers who are running on SAP ECC and want to move to S/4HANA but still retain their investment in the current framework, this is SAP’s recommendation.

You will be shifting the entire system and business process to a new S/4HANA platform with system conversion. If you do not want any changes in the operations of your business process, this approach could provide a better solution.
