Background
A manufacturing organisation operated a multi-entity ERP environment on Microsoft Dynamics NAV 2018, which was approaching end‑of‑life and required a transition to Microsoft Dynamics 365 Business Central Online. The modernisation needed to preserve all historical and transactional data, support ongoing finance and manufacturing operations, meet Australian data residency requirements, and be delivered within a 40‑day timeframe following partner constraints.
The Challenge
The organisation’s Microsoft Dynamics NAV 2018 environment had reached a critical transition point. The platform was approaching end-of-life, with increasing complexity associated with maintaining legacy C/AL customisations and supporting ongoing business change.
On-premises infrastructure introduced operational overhead and constrained scalability, while upgrade pathways had become increasingly complex and high risk.
A further constraint emerged when the incumbent implementation partner confirmed they could not deliver the required modernisation within the organisation’s timeframe, creating urgency for a partner capable of delivering a low-risk transition without disruption.
The Objective
- Transition from NAV 2018 to Business Central Online
- Preserve full historical and transactional data
- Maintain uninterrupted finance and manufacturing operations
- Align with enterprise architecture and governance standards
- Ensure Australian data residency compliance
- Deliver within 40 days
The Approach
The solution was deployed within Australian Azure datacentres to align with data sovereignty, governance, and compliance requirements. A full data migration was completed, encompassing master, transactional, and historical data, using Microsoft‑supported tooling to ensure continuity and data integrity.
As part of the modernisation approach, legacy C/AL customisations were refactored into AL extensions, reducing technical debt and aligning the solution with Microsoft’s cloud‑first architecture. The migration concluded with a controlled cutover, following a structured approach that included validation cycles and rehearsals to ensure operational continuity and minimise business disruption.
