ERP Migration and Integration: Microsoft Dynamics to Oracle

The client is a global manufacturer of professional-grade power tools and accessories, operating as a subsidiary of a larger industrial conglomerate. The parent company reported the client local-currency sales growth of 11.6 percent in 2024 and 7.9 percent in 2025, with margin expansion driven by the client's higher-margin mix. The firm has expanded beyond hardware into a connected-products software-and-data layer: their cloud-based jobsite-management platform (supporting over a hundred connected tools with geofencing, remote lockout, and digital torque reports), embedded ML across their battery platforms, and integrations into Procore and Autodesk BIM 360 that close the loop between the tool layer and project-management software. Taller's engagement at the power tools manufacturer has been continuous since 2021, sourced through a staffing partner, and spans five durable workstreams. The canonical ERP-integration workstream that Volume II covers (Dynamics AX 2012 R2 maintenance, the AX-to-Dynamics-365 migration, AX-to-Oracle ERP/SCM Cloud integration, and the Azure integration platform engineering) is the dominant footprint. Adjacent and growing is the modern data platform on Azure and Databricks, which accelerated through 2024, 2025, and 2026. A small React-on-AWS Serverless team surfaces IoT-tool diagnostic data for the client's internal reliability engineers. The EDI Managed Services lane connects the client to its dealer and distributor network. Taller engineers placed at this client have earned strong client-side reputations - a Taller engineer named "critical to the client" by the client manager in October 2024, another Taller engineer called a "rockstar" by the client manager, a Taller engineer confirmed "reliable, knowledgeable" by the client manager, a Taller engineer called "fantastic" by the Lead Oracle Developer in September 2025.

ERP migration in a global manufacturer is not a single project but a multi-year sequence of integrations, each preserving an operational capability that the business cannot afford to lose during transition. The power tools manufacturer's program had to move from MS Dynamics AX to Oracle ERP while keeping production-floor systems, channel-management workflows, and the financial reporting cadence intact.

Taller's team of AX Developers managed the integration layer between Dynamics and Oracle and provided technical leadership across the broader migration program. Integration work between AX and Oracle is harder than the average ERP cutover because both systems have opinions about the same business objects. Customer master data, vendor master data, item master data, and pricing logic each carry decades of operational habit inside Dynamics, and the right integration design preserves the intent of that habit rather than mechanically replicating the schema. The Azure Services substrate (Functions, Logic Apps, Service Bus, integration runtime) handles the message-bus mechanics; the API integration layer handles the contract-level translation between the two ERPs' object models.

Taller delivered the seamless ERP integration phase, with one Taller developer promoted to a leadership role on the broader client migration program. This was a signal that the engagement compounded into expertise the program needed to retain.

ERP modernization is one of the structural commitments a global manufacturer makes to its next decade of operations. The choice of integration partner during the transition matters disproportionately because the relationships built during the cutover often become the durable engineering partnerships that operate the system afterward.
