The transition from SAP ECC to S/4HANA is more than just a software upgrade—it’s a fundamental shift in how businesses operate and how SAP professionals must adapt. With SAP ending mainstream support for ECC in 2027, organizations are racing to modernize their ERP landscapes. This shift demands that SAP consultants, IT analysts, and business users reassess their skill sets to remain competitive in a cloud-first world.
While core business and ERP knowledge remains essential, many technical and functional skills are evolving. Traditional SAP expertise—such as configuring ECC transactions or maintaining on-premise infrastructure—will not be enough in an S/4HANA environment, where automation, embedded analytics, and cloud integration play a larger role.
This article explores:
The migration to S/4HANA is not just a technical shift—it’s a professional transformation. SAP professionals who adapt will find themselves in high demand, while those who remain locked into ECC-era skills may struggle to compete in the job market.
Despite the technological advancements in SAP S/4HANA, some foundational skills remain invaluable. While new tools and methodologies are being introduced, the fundamental business processes and ERP principles that SAP professionals have mastered over the years still hold significant weight.
SAP professionals who have a deep understanding of business operations—how finance, procurement, sales, and manufacturing work within SAP—will find their knowledge remains relevant. However, they must map these core concepts to S/4HANA’s modernized architecture to stay competitive.
Regardless of whether a company is running ECC or S/4HANA, SAP is still fundamentally an enterprise resource planning (ERP) system that helps businesses manage critical workflows. The need for professionals who understand end-to-end business processes is not going away.
ABAP, SAP’s core programming language, is not disappearing in S/4HANA, but it is evolving. Traditional ABAP development that relied on customizing standard SAP objects, excessive Z reports, and SQL-heavy coding* is being phased out in favor of modern, HANA-optimized development.
To stay relevant, ABAP developers must adapt by:
SAP professionals who were strong ECC developers but fail to modernize their skills will find their expertise diminishing in value as companies move toward Fiori, SAP BTP, and cloud-based extension models.
S/4HANA migrations are not just technical upgrades—they are full-scale business transformations. As a result, the ability to manage projects, drive change, and align stakeholders is just as valuable as technical expertise.
While functional expertise in SAP modules (FI, CO, MM, SD, etc.) is still crucial, the way these modules work in S/4HANA has changed.
SAP professionals who understand ECC processes but fail to learn how they have evolved in S/4HANA will struggle to remain competitive.
While domain expertise, project management, and ABAP programming remain essential, SAP professionals must adapt these skills to fit S/4HANA’s modernized landscape. Knowing how a process worked in ECC is no longer enough—you must also understand how it works in S/4HANA.
While many foundational SAP skills remain valuable, certain legacy skills and tools are quickly becoming outdated in the S/4HANA era. SAP’s modernization efforts focus on cloud adoption, process simplification, and automation, meaning that professionals who only rely on ECC-era skills without upskilling risk falling behind.
The following competencies are losing relevance or being phased out, making it imperative for SAP professionals to shift their focus to newer methodologies and technologies.
For decades, SAP end users and consultants relied on SAP GUI to navigate the system through transaction codes (T-Codes). In S/4HANA, however, SAP is shifting toward a Fiori-based, web-enabled interface, which is more intuitive and user-friendly.
What’s fading:
What’s replacing it:
SAP professionals who specialize only in SAP GUI transactions and customization will need to learn how the same business processes function in Fiori to remain relevant.
ABAP programming remains crucial in S/4HANA, but the way ABAP is used has changed dramatically. SAP is enforcing a "clean core" strategy, where businesses are discouraged from heavily modifying standard SAP code.
What’s fading:
What’s replacing it:
SAP developers who fail to modernize their ABAP skills will struggle as companies move toward HANA-optimized, cloud-friendly development.
In SAP ECC, companies could run SAP on various third-party databases like Oracle, Microsoft SQL Server, or IBM DB2. With S/4HANA, SAP exclusively runs on the HANA database, eliminating the need for third-party database tuning expertise.
What’s fading:
What’s replacing it:
Database administrators who only specialize in Oracle DB or SQL Server for SAP workloads will need to shift their focus to HANA-specific optimizations.
SAP professionals with ECC 6.0 certifications will find that many older credentials no longer align with the S/4HANA landscape.
What’s fading:
What’s replacing it:
While ECC-era certifications still demonstrate foundational knowledge, SAP professionals must update their credentials to reflect S/4HANA expertise to remain competitive in the job market.
SAP’s shift toward Fiori-based UIs and mobile-friendly applications means that older UI development technologies are becoming less relevant.
What’s fading:
What’s replacing it:
SAP developers and functional consultants must understand how to navigate, configure, and develop in Fiori, as reliance on SAP GUI will continue to decrease over time.
SAP professionals who do not modernize their skills risk being left behind. The shift to S/4HANA and the cloud means that expertise in SAP GUI, heavy ABAP customizations, third-party databases, and outdated certifications will lose value.
To stay competitive, SAP professionals must transition from legacy methods to modern best practices, particularly in Fiori, HANA-optimized development, cloud integration, and process standardization.
As SAP S/4HANA adoption accelerates, companies are looking for professionals who can bridge the gap between legacy ECC expertise and the capabilities of a modern, cloud-driven ERP system.

Hands-on experience is the most valuable asset in any SAP professional’s career. Organizations that are still in the planning phase of an S/4HANA migration provide an opportunity for internal employees to participate in pilot projects.
Even if someone’s role does not require them to be part of the core migration team, finding ways to contribute—such as participating in testing, configuration reviews, or process mapping—can provide exposure to real-world S/4HANA implementations.
Consultants who work with external clients should proactively seek opportunities to shadow S/4HANA projects or take on small responsibilities related to migration efforts. Gaining even limited hands-on experience with S/4HANA configurations, Fiori apps, or analytics tools is better than waiting until full-scale migration projects become the only available work.
The SAP ecosystem is vast, and staying engaged with the community provides significant benefits. Professionals who actively participate in SAP forums, LinkedIn groups, and industry conferences stay informed on new releases, upcoming changes, and evolving best practices.
Attending events such as SAP TechEd or local SAP user groups allows professionals to network with experienced S/4HANA consultants and learn directly from those who have already gone through migration projects. These insights can be more valuable than standard training materials, as they reflect real-world implementation challenges and solutions.
The SAP landscape is evolving beyond just ERP functionality. As organizations embrace cloud-based applications and AI-driven analytics, SAP professionals must expand their knowledge to include adjacent technologies that integrate with S/4HANA.
For example, an SAP finance consultant should consider learning about SAP Analytics Cloud (SAC) and Group Reporting, as financial reporting is increasingly shifting toward real-time, cloud-based solutions. Likewise, SAP HR consultants should familiarize themselves with SAP SuccessFactors, as many companies move HR and talent management processes away from on-premise solutions.
Technical consultants and developers should explore SAP Business Technology Platform (BTP) and cloud-based integration tools, as organizations increasingly prefer side-by-side extensibility over core modifications.
By broadening their skill sets, SAP professionals can position themselves for higher-value roles that go beyond traditional ERP consulting.
Organizations adopting S/4HANA are also modernizing their software development and deployment processes. The rise of continuous integration/continuous deployment (CI/CD) for SAP, as well as automated testing and cloud-native development, means that SAP professionals should familiarize themselves with these practices.
Functional consultants should become comfortable with tools that automate testing and regression analysis, as quarterly updates in cloud-based S/4HANA require frequent validation of business processes.
Developers should explore modern DevOps approaches for SAP, including Git-based transport management, containerization, and SAP-focused automation frameworks.
Those who understand how to integrate automated workflows and quality control processes into SAP projects will have a significant advantage over those who rely on outdated manual deployment methods.
The move to S/4HANA is an opportunity for growth, not just disruption. SAP professionals who take an active role in learning, adapting, and applying their expertise in new ways will continue to thrive in the evolving SAP job market.
Waiting for an employer to provide training or hoping that ECC knowledge will remain sufficient is not a viable strategy. The best way to future-proof a career in SAP is to embrace change, proactively acquire new skills, and stay engaged with the broader SAP ecosystem.
The transition from SAP ECC to S/4HANA is more than just an upgrade—it is a fundamental shift in how organizations manage business processes, data, and system architecture.
