From Bottlenecks to Breakthroughs: How Tricentis and TTC Global Accelerate and De-risk S/4HANA Migrations
Published: 5 September 2025
As SAP winds down support for ECC systems, organisations face significant risk from delays, disruptions, or misalignment. Even well-prepared teams might encounter data inconsistencies or missing code that require costly fixes in production. In our joint eBook with Tricentis, we address the common bottlenecks that turn migrations into crises, and what a structured quality engineering approach produces in practice.
Key Insights Inside
The Most Common Causes of SAP Go-live Failure
The same set of problems recurs across organisations regardless of size or industry. Understanding them in advance allows teams to plan around them rather than discover them under pressure:
- Complexity and scoping challenges: Poor scope definition, overlooked interface dependencies, and assumptions that existing workflows will transfer unchanged lead to rework and delays.
- Business process validation gaps: Treating validation as a final-phase activity means that cross-module and cross-system failures surface too late to resolve without disruption.
- Performance risks and regression testing: Functional readiness does not equal performance readiness. Without realistic load testing and targeted regression strategies, minor issues become major slowdowns post go-live.
- Post-migration realities: Inadequate change management, missing regression suites, and insufficient post-migration validation leave organisations exposed long after Day 1.
- Custom code and data migration: Legacy ABAP customisations require impact analysis and re-engineering. Failure to identify redundant or non-compliant code creates functionality gaps that only appear in production.
- Resource constraints: SAP-proficient talent with both technical and domain knowledge is scarce. Without delivery support, timelines slip and test quality deteriorates.
Frequently Asked Questions
Who is this eBook for?
This guide is written primarily for SAP Programme Directors, Enterprise Architects, and Heads of Quality Engineering planning an S/4HANA migration 6 to 12 months out, alongside CIOs and IT leadership who need visibility into where migration risk concentrates before budget and scope are locked in.
What are the biggest causes of failed SAP migrations?
Failed S/4HANA migrations are rarely caused by the platform itself. Recurring causes are undefined scope, unvalidated customisations, misaligned stakeholders and data that does not survive the transition intact. Each is addressable through structured QA introduced before the migration begins, not after issues surface in production.
What are the main risks of an SAP S/4HANA programme?
The main risks sit in areas standard testing often treats as secondary: data integrity across transformed datasets, third-party integrations with banking and CRM systems, performance under real transaction volumes, and security configurations such as role-based access. A risk-based testing strategy scopes effort to where business impact is greatest, rather than testing everything equally.
How do we ensure data integrity during SAP transformations?
Data integrity requires automated validation of migrated records against source data, not manual spot-checks. Tools such as Tricentis Data Integrity confirm that master and transaction data, financial reporting and compliance-relevant records remain accurate and complete throughout the transformation, with traceable audit trails to support regulations such as GDPR or SOX.
Why use an independent QA firm rather than the SAP implementation partner for testing?
When the systems integrator that builds the solution also signs off on its quality, validation carries a conflict of interest. An independent QA partner separates delivery from assurance, so testing outcomes are governed without pressure to protect a go-live date. TTC Global does not implement SAP; it validates it.
