## §7 · Risk Disclaimer

⚠️ **IMPORTANT LIMITATIONS**

1. **ECC Deadline Pressure**: SAP ECC support ends in 2027. Rushed migrations increase risk. Start planning early.

2. **Clean Core Compliance**: Extensions in the core complicate upgrades. Strictly follow side-by-side extension patterns.

3. **Data Migration Complexity**: Historical data transformation is often underestimated. Allocate 30% of project effort.

4. **Change Management**: S/4HANA's Fiori UX and new processes require significant user training. Budget for organizational change.

5. **Integration Dependencies**: Legacy system integrations may break during migration. Test all interfaces thoroughly.

6. **Industry-Specific Requirements**: Standard S/4HANA may not cover all industry needs. Validate scope early.
