With the looming date of 2027 fast approaching, the countdown clock is now ticking for businesses running SAP ECC solutions. For many companies, 2026 marks the deadline for evaluation and preparation towards an effective SAP S/4HANA migration process. Companies delaying their SAP S/4HANA assessments now can find themselves struggling with rushed implementations, costly migrations, operational problems, compliance issues, and increasing dependence on expensive extended maintenance packages.
It is a matter of record that SAP plans to discontinue mainstream maintenance for SAP ECC by 2027, making it imperative that businesses upgrade to the new and more advanced SAP S/4HANA solution for a competitive edge. In addition, there have been several warnings from industry experts that any delays with SAP S/4HANA migration will make such efforts unrealistic to achieve.
In the face of this dilemma for businesses considering a shift to SAP S/4HANA, there is only one logical step forward: companies must begin their SAP S/4HANA evaluation now and embark upon the journey toward migrating to intelligent ERP solutions.
At Nexxora Inc. and Nexxora Technology companies, we undergo a detailed SAP S/4HANA assessment to ensure a smoother migration process.
SAP ECC has been supporting enterprise processes for years now, managing finances, supply chain, procurement, human resources, manufacturing, logistics, and general business operations worldwide. Nevertheless, technological advancement, adoption of cloud computing, AI analytics, and real-time business intelligence have shifted the standards for modern ERP systems.
In response to the ever-evolving business demands, SAP S/4HANA has been developed with features such as:
SAP has continuously encouraged companies to shift to S/4HANA in order to benefit from innovations and mainstream support.
Organizations that fail to adopt S/4HANA past support dates may face issues like:
This is precisely why 2026 is critical.
Most companies overlook the amount of time necessary for SAP migrations. SAP S/4HANA migration is a complex business transformation project that includes technology, data, processes, infrastructure, security, integration, and people.
According to industry benchmarks:
Organizations beginning their assessments at the end of 2026 will likely face a tough situation.
A correct SAP S/4HANA assessment allows enterprises to know:
Without this assessment stage, an enterprise cannot make informed decisions.
The main problem that leads to delayed SAP migration plans is the illusion of “we still have time.” However, at the moment, there is already growing demand for SAP consultants, migration, and transformation professionals.
SAP professionals’ forums mention several issues:
The longer organizations wait, the harder it is to attract professional implementation partners, remain flexible throughout the process, and control migration costs.
Early start of migration provides several competitive advantages for companies:
Some companies tend to consider a simple audit of the system as an SAP assessment. However, a full-fledged SAP S/4HANA assessment covers all components of the company’s landscape.
It includes reviewing the current state of the SAP ECC environment, specifically:
The objective is to identify what can be retained, optimized, retired, or redesigned.
Data migration is one of the most overlooked components of SAP transformations.
Low-quality master data, duplicate entries, inconsistent schemas, and obsolete historical information can impact migration efforts adversely.
Tasks involved include:
For many SAP experts, proper data preparation is the most crucial element in S/4HANA implementations.
Companies that have used SAP ECC for decades have considerable custom developments.
However, not all legacy customizations are required within SAP S/4HANA.
The assessment team analyzes:
Eliminating unnecessary customizations makes migration easier and reduces maintenance costs.
Today, more and more companies adopt hybrid or cloud-based ERP strategies.
SAP S/4HANA assessments allow businesses to decide on:
This stage is critical for enterprises planning digital transformation initiatives beyond ERP migration.
SAP S/4HANA migration should not merely copy existing inefficiencies into the new system.
Assessment highlights potential for process improvement:
Companies that streamline their business processes through migration experience far greater value from their S/4HANA investment.
Every company needs a migration strategy tailored to its specific needs and capabilities.

SAP S/4HANA helps businesses:
The businesses that start planning their transformations now will have an advantage in the future.
Moving from SAP ECC to SAP S/4HANA will not be a choice anymore for those corporations that seek sustainability. Given that 2027 will come soon, 2026 will be the year when it is time to assess ERP readiness, prepare the strategy, and start making adjustments.
Further delays may only increase complications and expenses related to the process.
