This catalog provides the foundational knowledge base used by the Agentic ERP Migration Planner. It includes common migration approaches, typical phases, known risk categories, and industry benchmarks. All data is static and open for enterprise customization.
| Approach | Description | Typical Duration | Risk Level | Best For |
|---|---|---|---|---|
| Big Bang | Single cutover event — old system off, new system on | 6–12 months | High | Smaller organizations, greenfield implementations |
| Phased (by module/geography) | Roll out modules or business units sequentially | 12–24 months | Medium | Most common enterprise approach |
| Hybrid / Parallel Run | New system runs alongside old for validation period | 18–36 months | Low–Medium | High-risk industries (finance, healthcare) |
| Technical Upgrade Only | Same vendor, version upgrade (e.g., ECC → S/4HANA technical) | 9–18 months | Medium | Minimal process change needed |
| Phase | Key Activities | Typical Duration |
|---|---|---|
| Discover & Assess | Current state analysis, fit-gap, business case | 2–4 months |
| Design & Blueprint | To-be processes, data migration strategy, customizations | 3–6 months |
| Build & Configure | System setup, development, integrations | 6–12 months |
| Test & Validate | Unit, integration, UAT, performance testing | 4–8 months |
| Cutover & Deploy | Data migration, go-live, hypercare | 1–3 months |
| Optimize & Stabilize | Post-go-live enhancements, knowledge transfer | Ongoing |
| Category | Examples | Severity Triggers |
|---|---|---|
| Data Migration | Data volume > 1TB, legacy custom tables, poor data quality | High if historical data > 10 years |
| Custom Code | > 5,000 custom objects, heavy Z-code, deprecated APIs | High if > 20% of functionality custom |
| Integrations | > 50 third-party interfaces, real-time sync required | High if mission-critical (banking, payroll) |
| Business Process Change | Standardization across geographies, new operating model | High if multiple legacy instances |
| Organizational Readiness | Limited internal expertise, resistance to change | High if no prior cloud experience |
| Compliance & Regulatory | SOX, GDPR, industry-specific (e.g., GxP, HIPAA) | High in regulated industries |
| ERP System | Average Project Cost | Average Duration | Success Rate |
|---|---|---|---|
| SAP ECC → S/4HANA | $10–50M | 18–36 months | 65–75% |
| Oracle EBS → Cloud | $8–40M | 15–30 months | 70% |
| Dynamics AX → D365 | $5–25M | 12–24 months | 80% |
