SAP to Infor Migration
Migrating from SAP to Infor is a material undertaking. The platforms differ in architecture, data model, integration approach, and — in many cases — the business processes they support well. This page covers why organisations make this move, what the migration involves technically, and the hard part that is consistently underestimated.
Why organisations move from SAP to Infor
- TCO: SAP typical budget is $500,000–$5,000,000. Infor typical budget is $200,000–$2,500,000. If the gap is material, cost reduction is often cited as a driver — though migration cost should be modelled against that saving.
- Deployment fit: SAP deploys as: Cloud (RISE), On-premise, Hybrid. Infor deploys as: Cloud (SaaS). A cloud-first mandate frequently drives migrations from on-premise or hybrid platforms.
- Industry fit: Infor is strongest in Healthcare, Manufacturing, Distribution, Fashion. If this aligns better with your industry, it can be a fit argument alongside cost.
- Vendor direction: ERP vendors actively push customers toward newer platforms. PeopleSoft customers being moved toward Oracle Fusion, and SAP R/3 customers toward S/4HANA, are the most common examples.
Migration at a glance
| SAP (source) | Infor (target) | |
|---|---|---|
| Deployment | Cloud (RISE), On-premise, Hybrid | Cloud (SaaS) |
| Integration approach | SAP Integration Suite (iFlow); pre-built connectors for Salesforce/Workday; REST/OData APIs | Infor ION middleware; REST APIs; pre-built connectors |
| Compliance modules | SOX, HIPAA, GDPR, ASC 606 | SOX, HIPAA, GDPR |
| Typical implementation | 12–36 months | 9–24 months |
| Pricing model | Subscription + services | Subscription |
Migration sequence
- Current-state audit: Document every module in use, every integration, every customisation, and every report. This takes longer than expected — plan 4–8 weeks for a typical mid-market estate.
- Data mapping: Map SAP data structures to Infor equivalents. Identify gaps. Define the transformation logic for each field. Agree which historical data migrates and which is archived.
- Integration redesign: SAP uses SAP Integration Suite (iFlow); pre-built connectors for Salesforce/Workday; REST/OData APIs. Infor uses Infor ION middleware; REST APIs; pre-built connectors. Every integration point needs individual assessment — do not assume connectors port across.
- Parallel run: Run both systems simultaneously for at least one period-end close. Reconcile outputs. Resolve discrepancies before cutting over.
- Cutover: Define the cutover window, the go/no-go criteria, and the rollback procedure. For ERP migrations, rollback is rarely possible after financial period close — plan the cutover to avoid straddling a period boundary.
- Post-migration managed services: The first 90 days after cutover carry the highest incident risk. Define the hypercare SLA before go-live, not after.
The hard part
On SAP-to-Infor migrations specifically, the thing that consistently causes timeline overrun is: historical data migration — most organisations underestimate the volume of legacy data that requires cleansing before it is fit to load into Infor. Organisations that have assessed this risk early and allocated budget for it tend to land on schedule. Those that surface it during data migration typically add 3–6 months.
Effort range
A SAP-to-Infor migration for a mid-market organisation typically runs 9–24 months from project kickoff to go-live, at a total cost in the range of the Infor implementation budget above. Organisations with significant customisation or integration complexity should apply a 1.5× multiplier to both time and cost. These are ranges with stated assumptions — they are not commitments.
