ERP Modernisation with Microsoft Dynamics 365: Lessons from Industry Leaders
Based on insights from the Modernising to the Cloud with Microsoft Dynamics 365 virtual panel discussion — co-hosted by Yes Dynamic and Sonata, November 2021.
Moving off a legacy ERP system is one of the most consequential infrastructure decisions an organisation can make. Done well, it unlocks real-time financial visibility, operational agility, and a platform built for growth. Done poorly, it disrupts the very business it was meant to improve.
To explore what separates successful migrations from difficult ones, Yes Dynamic and Sonata brought together senior leaders from Microsoft, Peppermint Technology, R-kioski, Brunswick, and CPL Aromas. These are organisations that have lived through ERP transformation projects on Microsoft Dynamics 365. What follows are the key lessons from that conversation, with broader context for organisations considering the same journey.
Our Panelists
1. Alfred Muthunathan — Chief Information Officer, CPL Aromas
2. Maria Sjööroos — IT & HR Director, R-kioski Oy
3. Rob Hyland — Divisional Chief Information Officer, Brunswick
4. Michael Crowley — Director of Sales Excellence & Strategy, Microsoft
5. Mike Walker — Chief Technology Officer, Peppermint Technology
6. Hanumanth Tenneti — Competency Head, Microsoft Dynamics, Sonata Software
Together, they shared first-hand perspectives on cloud ERP adoption, migration strategy, and the realities of digital transformation at scale.
Why Organisations Are Moving Off Legacy ERP
Legacy ERP platforms were built for a different era. They are costly to maintain, difficult to integrate with modern tools, and structurally incapable of delivering the real-time visibility today’s operations demand.
The most common triggers driving migration to Dynamics 365:
End-of-support deadlines on existing platforms forcing an immediate decision
Inability to integrate with modern data, CRM, or e-commerce systems
Escalating IT costs tied to on-premise infrastructure and custom development
Leadership demand for real-time financial and operational reporting
Growth into new markets or business models the legacy system cannot support
From the panel
Across all five organisations represented in the discussion, the decision to migrate was ultimately driven by a strategic inflection point — not just a technical one. The technology question came second; the business case came first.
What Microsoft Dynamics 365 Delivers
Dynamics 365 is a suite of connected applications built on a common data model and Microsoft Azure. The two most commonly implemented modules for ERP modernisation are Dynamics 365 Finance (for mid-to-large enterprises with complex financial operations) and Business Central (for SMEs needing a fast-to-deploy, full-featured ERP). Both connect natively to the Power Platform without custom middleware.
Unified financial management
General ledger, accounts payable/receivable, fixed assets, and budgeting in a single system, with real-time reporting and automated close cycles.
Operations and supply chain visibility
A live view of inventory, supplier performance, and order status from procurement through to fulfilment. Logistics-intensive businesses have used this to reduce stock discrepancies and improve delivery accuracy.
Native AI through Microsoft Copilot
Predictive cash flow forecasting, intelligent invoice matching, and natural language querying of business data built into the platform.
Scalable multi-entity structure
For organisations operating across territories such as Brunswick and R-kioski, Dynamics 365 Finance handles legal entity separation, intercompany transactions, consolidated reporting, and real-time FX management within a single deployment.
What Successful Deployments Look Like
| Area | What organisations report |
| Finance close cycle | Automated reconciliation and real-time ledger updates cut monthly close times across most deployments |
| IT maintenance cost | Cloud ERP consistently delivers lower 5-year TCO versus maintained on-premise equivalents |
| Integration footprint | Teams, SharePoint, and Outlook connect directly, eliminating duplicate data entry across most workflows |
| Post-go-live stability | Organisations with structured data migration and parallel-run periods report significantly fewer critical issues at go-live |
Outcomes vary by organisation size, industry, implementation quality, and change management investment.
Four Factors That Separate Smooth Migrations from Painful Ones
Not every Dynamics 365 migration delivers on its promise. Based on the experiences shared in the panel and Yes Dynamic’s own Dynamics 365 migration work, the difference consistently comes down to four things:
Scope clarity before kickoff
Define what is being migrated, what is being redesigned, and what is being retired, before configuration begins. Scope creep is the leading cause of cost overruns in ERP projects.
Clean, validated data
Data migration is routinely underestimated. Organisations that invest in deduplication and validation before go-live avoid the most common post-migration failures: incorrect financial balances, broken supplier records, and inventory discrepancies.
Business-led implementation teams
The finance director, operations manager, and warehouse lead need to be in the room, not just IT. ERP systems encode business processes; getting those processes right requires the people who run them.
Phased or parallel approach
Running legacy and new systems in parallel for a defined period reduces go-live risk considerably. For multi-entity or multi-currency organisations, a phased rollout by business unit or region is often the most pragmatic path.
Panelist insight: multi-territory deployments
Rob Hyland (Brunswick) and Maria Sjööroos (R-kioski) both highlighted that multi-location businesses face distinct challenges — particularly around currency management, intercompany transactions, and consolidated reporting. Dynamics 365 Finance is purpose-built for these structures, which was a decisive factor in both organisations' platform selection.
Is a Dynamics 365 Migration Right for Your Organisation?
If your organisation is experiencing any of the following, a scoped assessment is worth prioritising:
Your current ERP vendor has announced end-of-support within the next 24 months
Month-end close takes more than five working days and requires significant manual effort
You cannot get a consolidated real-time view of cash, inventory, or financial performance
IT spends more time maintaining customisations than improving the system
You are planning an acquisition, geographic expansion, or significant operational change
Organisations with a recently upgraded, well-performing ERP and no immediate strategic drivers may find the disruption cost outweighs near-term benefit. An honest gap assessment of your current platform is the right starting point.
