Programme context
Iriso completed a big-bang transition from its legacy ERP to Dynamics 365 Finance, going live in April 2024 across 11 group companies.
Why this matters: The record identifies a named organisation, an explicit predecessor and destination platform, and a bounded workload and lifecycle stage.
Migration timeline

Workload migration matrix
| Workload | Predecessor | Destination | Status by 23 Jul 2026 |
|---|---|---|---|
| Sales, purchasing, production, accounting, intercompany transactions and related data links | Ageing legacy on-premises ERP supporting global core operations | Microsoft Dynamics 365 Finance on Azure in one instance for 11 group companies | Completed big-bang ERP migration |
Implementation and architecture
- One Dynamics 365 Finance instance supports 11 group companies.
- The deployment covers fewer than 600 users.
- Future MES, PLM and broader standardisation work are not treated as completed.
Known unknowns and contradictions
- The predecessor ERP vendor and product name.
- The complete residual legacy-system inventory.
- Exact retirement dates for ancillary systems.
No missing fact is inferred to broaden the source-supported migration claim.
PlatformTrace analysis
The source explicitly supports completion of the ERP transition. The predecessor product name is not published, and later MES, PLM and additional standardisation work remain future scope.
Performance, cost, uptime and operational outcomes remain attributed source claims unless independently stated otherwise.
