In 2025, businesses across industries are modernizing their enterprise resource planning (ERP) systems to stay competitive, agile, and resilient. For many, this means upgrading to the latest SAP S/4HANA platform and adopting cloud-based solutions. But one significant hurdle remains: data migration. That’s where expert SAP support becomes vital.
Migrating data from legacy systems to a modern SAP environment is a high-stakes process. It involves more than just moving data from point A to point B. Ensuring accuracy, security, compliance, and minimal disruption to operations is a complex endeavor—one that requires experienced SAP support.
In this article, we’ll explore the most prominent data migration challenges organizations face today, highlight why they matter more than ever, and explain how partnering with a proven SAP expert can simplify and safeguard the journey.
Why Data Migration Is More Complex Than Ever
The complexity of data migration has grown exponentially due to several trends:
- Hybrid and multi-cloud environments: In 2024, 73% of enterprises adopted a hybrid cloud model, making cross-environment data integration more difficult.
- Exploding data volumes: IDC predicts that global data will grow to 175 zettabytes by 2025. Moving even a fraction of that between systems without data loss or corruption is a monumental task.
- Increased regulatory scrutiny: With the GDPR, CCPA, HIPAA, and industry-specific standards such as FISMA or FINRA in effect, organizations must ensure that data migrations maintain compliance.
- Shorter transformation timelines: The pressure to innovate quickly is increasing. Many companies now aim to complete digital transitions in 6–12 months, leaving less room for error.
Top Data Migration Challenges in SAP Projects
Let’s break down the most critical challenges that can make or break your SAP migration.
1. Preserving Data Integrity
Data integrity, which ensures information is accurate, complete, and unaltered during migration, is the cornerstone of a successful transition. Issues like duplicated records, missing fields, or incompatible formats can lead to reporting errors, compliance violations, and operational disruptions.
In SAP environments, where modules are tightly interconnected, even minor inconsistencies can ripple through finance, procurement, and HR systems. Tools like SAP Data Services and SAP Advanced Data Migration can help—but only if they are correctly configured and utilized.
Best Practice: Collaborate with an SAP support partner that can perform thorough data profiling, cleansing, and validation both before and after migration.
2. Ensuring Data Security and Privacy
Data breaches during migration are on the rise. In 2024, IBM reported that the average cost of a data breach reached $4.9 million, an all-time high. Migration windows are especially vulnerable because security protocols, such as encryption and user access controls, may not be fully effective during transit.

Compliance with data privacy laws is also critical. Any leak of personal identifiable information (PII) during migration could trigger regulatory penalties and brand damage.
Best Practice: Select an SAP partner that implements end-to-end encryption, monitors access through role-based controls, and utilizes secure, compliant tools for migration.
3. Minimizing Downtime
Whether you’re operating a manufacturing line, an e-commerce storefront, or a financial services portal, unplanned downtime during data migration can cost thousands of dollars per minute. According to research, the average cost of IT downtime his around $9,000 for large organizations.
Even planned downtime needs to be short, strategically timed, and communicated across departments. The SAP system must remain usable during most of the transition, especially in 24/7 global operations.
Best Practice: Rely on SAP consultants with proven cutover strategies and high-availability infrastructure to ensure your business remains operational during the switch.
4. Comprehensive Testing at Every Stage
Inadequate testing is one of the most common causes of post-migration issues. Data may appear correct but fail to support processes such as payroll runs, purchase orders, or revenue recognition.
Proper testing includes:
- Unit testing of individual components
- Integration testing across modules and systems
- User acceptance testing (UAT) with real-world scenarios
- Reconciliation testing to ensure data fidelity between source and destination
Best Practice: Utilize automated testing frameworks and collaborate with SAP experts who possess in-depth knowledge of your industry's specific workflows.
5. Managing Stakeholder Expectations
Data migration isn’t just an IT initiative, but a transformation. That’s why stakeholder buy-in is essential. If end users, department heads, or executive sponsors aren’t kept informed or trained on the changes, adoption may falter, and the project's ROI will suffer.

Stakeholders often underestimate the amount of historical data required or overestimate the speed of the migration. Education, transparency, and proactive communication are essential to managing expectations effectively.
Best Practice: Assign a dedicated SAP support team to collaborate with stakeholders and provide regular updates, training, and opportunities for feedback throughout the migration.
New in 2025: Emerging Data Migration Challenges
As we move deeper into the decade, new challenges are surfacing that didn’t exist a few years ago:
AI and Automation Conflicts
While many organizations are integrating AI tools for business intelligence and automation, these systems rely on high-quality, well-structured data. A flawed migration can lead to inaccurate AI outputs and failed process automation.
Real-Time Data Syncing
With real-time data streaming becoming more common in logistics, finance, and customer service, ensuring that the migration doesn’t interrupt live data feeds has become more complex.
Migrating Unstructured Data
Documents, PDFs, videos, and social media interactions are increasingly essential business assets. Migrating and tagging unstructured data accurately is an emerging priority, particularly for sectors such as healthcare and law.
