As global trade becomes increasingly complex, organizations are under growing pressure to manage trade compliance, customs, export controls and international trade processes efficiently while maintaining accurate and reliable business data.
For organizations still operating on older versions of SAP Global Trade Services, migration to SAP Global Trade Services, edition for SAP HANA (SAP GTS E4H) can represent an important step toward modernizing their global trade landscape.
But GTS migration is not simply a technical upgrade.
A successful transition requires careful consideration of business processes, configuration, custom developments, master data, integrations, historical data, compliance requirements and testing.
The transition to GTS E4H may involve changes to existing functionality, processes and system behavior. Organizations should therefore assess these changes early to identify potential impacts on configuration, custom developments, integrations and business processes.
Why Are Organizations Moving to SAP GTS E4H?
SAP GTS E4H provides a modern platform for managing global trade processes and integrates with enterprise systems such as SAP S/4HANA.
Depending on the organization’s requirements, GTS can support areas such as:
- Trade compliance
- Sanctioned Party List screening
- Embargo checks
- Legal control
- Customs management
- Product classification
- Preference management
- Trade-related reporting
- Integration with feeder systems
SAP’s current documentation describes integration between S/4HANA and GTS across areas including Compliance, Customs and Preference Management.
For organizations planning their next-generation SAP landscape, this makes GTS E4H migration more than a technology exercise—it becomes an opportunity to review and improve the overall trade architecture.
Migration Is More Than a Technical Conversion
One of the biggest mistakes organizations can make is to treat GTS migration as simply:
Old system → New system
A GTS environment typically contains years of:
- Custom configuration
- Custom developments
- Business rules
- Master data
- Interfaces
- Compliance processes
- Classification data
- Historical documents
- User-specific processes
- Integrations with feeder systems
The migration therefore needs to answer a much more important question:
What should be carried forward, what should be redesigned, and what should be retired?
Key Considerations for a GTS E4H Migration
1. Assess the Existing GTS Landscape
Before beginning the migration, organizations should establish a clear picture of the current environment.
This includes reviewing:
- Current SAP GTS version
- Connected feeder systems
- GTS functional areas in use
- Custom developments
- Interfaces
- Custom tables
- Reports
- Enhancements
- Batch jobs
- Business-critical processes
- Existing compliance controls
SAP provides a Conversion Guide specifically for technical information related to conversion from previous GTS releases to GTS E4H.
2. Understand the Migration Approach
The appropriate approach depends on the organization’s current landscape and business objectives.
Potential strategies may include:
Brownfield / System Conversion
Organizations can retain a significant portion of their existing system configuration, data and custom developments while moving to the newer platform.
This can help reduce the need for complete reimplementation, but existing customizations and processes still need careful assessment.
Selective Data Migration
Organizations may choose to selectively move relevant data and processes into the target environment.
This can be useful where the organization wants to clean up legacy data or redesign selected processes.
Greenfield Implementation
In some situations, organizations may determine that a new implementation is more appropriate than carrying forward the existing landscape.
The decision should be based on:
Business requirements + technical landscape + data quality + customizations + future roadmap.
The appropriate migration approach depends on the organization’s current landscape, business objectives and future SAP roadmap. Organizations can generally evaluate brownfield/system conversion, selective data migration or a greenfield implementation based on their specific requirements.
3. Master Data and Data Migration
Master data is one of the most critical foundations of a successful SAP GTS environment. During migration, organizations should carefully assess the quality, completeness and relevance of existing data, including:
- Business partners
- Customers and suppliers
- Products/materials
- Product classifications
- Bills of material
- Preference-related data
- Other trade-related master data
Organizations should determine:
What data exists? → Is it accurate? → Is it still required? → What needs to be cleansed? → What needs to be transformed or mapped? → What should be migrated?
A structured approach to data cleansing, mapping, validation and migration can significantly reduce errors and downstream issues after the new GTS environment goes live.am issues.
4. Integration Assessment
Integration is another critical consideration in a GTS migration. GTS typically operates as part of a broader enterprise landscape and may exchange data with systems such as SAP S/4HANA, SAP ERP, SAP TM, SAP EWM, external customs platforms and other third-party applications.
During migration, organizations should therefore assess:
- Existing interfaces and integration points
- Master-data replication
- Transactional data flows
- Custom interfaces
- External customs and compliance integrations
- Middleware and integration dependencies
- Changes required in the target architecture
The objective is to ensure that data flows reliably across all connected systems and that critical trade processes continue to operate without disruption after migration.
5. Custom Code and Customization Review
Legacy GTS implementations often contain custom developments built around specific business requirements.
During migration, organizations should classify these into:
Keep → Modify → Replace → Retire
This prevents unnecessary legacy customization from being carried into the new environment.
A migration can therefore be an opportunity to simplify the GTS landscape rather than simply reproducing every historical customization.
6. Compliance & Business Process Validation
Technical migration alone does not guarantee that the business will operate correctly after go-live.
Organizations should validate critical trade processes such as:
- Import compliance
- Export compliance
- Sanctioned Party Screening
- Embargo checking
- Legal Control
- Product classification
- Customs processes
- Preference determination
- Reporting
The goal should be to ensure that the migrated system supports the actual business process, not merely that the technical conversion completes successfully.
7. Testing Should Be Business-Scenario Driven
Testing should go beyond checking whether individual transactions work.
Organizations should develop end-to-end scenarios such as:
Sales Order → Compliance Check → Delivery → Export Process → Customs → Goods Movement
and:
Purchase Order → Import → Compliance → Customs Declaration → Goods Receipt
Testing should include:
- Unit testing
- Integration testing
- End-to-end testing
- Regression testing
- Negative testing
- User acceptance testing
- Compliance scenario testing
This is particularly important because a GTS issue can potentially affect both business operations and regulatory compliance.
8. Cutover & Go-Live Planning
A well-designed cutover plan should address:
- Data migration
- Interface activation
- Open transactions
- Master-data synchronization
- Background jobs
- User access
- Compliance checks
- Customs processes
- Business validation
- Rollback/contingency planning
The objective should be to minimize disruption to global trade operations.

A Migration Should Also Be an Opportunity to Improve
The objective of a GTS E4H migration should not simply be:
“Move everything from the old system to the new system.”
Instead, organizations should ask:
“How can we use this migration to create a simpler, more integrated and future-ready global trade environment?”
This means reviewing legacy processes, improving data quality, rationalizing customizations and aligning GTS with the organization’s broader S/4HANA and global trade strategy.
