A Guide for SMBs on Legacy ERP to Dynamics 365 Business Central Migration
Section
- Problem with Legacy ERP: Legacy on-premises ERP systems fragment data, slow decision-making (long closing cycles, delayed, manual reconciliations), create brittle integrations, incur high ownership costs, and lack scalability and security, keeping SMBs in reactive mode.
- Benefits of Migrating to Dynamics 365 Business Central: Dynamics 365 Business Central centralizes finance and operations data, enables real-time visibility, elastic scaling, and AI-enhanced forecasting. This speeds up closures, reduces costs, and improves responsiveness, with documented ROI of more than 100%.
- Operational Enablement & Outcomes: Includes integration patterns with observability guardrails, success gates, and KPI scorecards (e.g., improving DSO, inventory turn, and reducing IT spend) to drive measurable business improvement and transition from reactive to predictable execution.
At some point in the growth journey of every small or medium-sized business (SMB), a familiar tension appears: the need to move faster outpaces the ability of legacy systems to keep up. What once felt reliable begins to feel restrictive. Reporting lags. Decisions stall. Teams spend more time fixing data than using it.
Many respond by taking incremental steps like adding a cloud database or analytics tool here and a point integration there, hoping to gain enough flexibility without disrupting the core. But these piecemeal efforts often fall short. Without a truly integrated, cloud-native foundation, these efforts can’t deliver the expected ROI, and operational challenges still exist, in new forms.
A well-planned migration to Microsoft Dynamics 365 Business Central changes that equation. More than just an ERP replacement, it offers a chance to unify data, streamline operations, and enable intelligent, real-time decision-making across the business. It’s why Forbes Advisor named Dynamics 365 Business Central the Best Cloud ERP Software of 2024—recognizing its ability to drive both operational efficiency and long-term growth.
Why Legacy ERP Holds SMBs Back
Legacy ERP systems once served their purpose. But today, they slow decisions and create operational hurdles just when agility matters most. Finance and operations teams often spend hours reconciling mismatched data across ledgers, inventory, and sales just to close the books or build a forecast. Instead of acting on insights, they’re often buried in simple reporting and cleanup.
To cope, many businesses layer in manual exports, custom connectors, or one-off tools. But these fixes introduce technical debt. Over time, even small changes become risky, support costs go up, and agility drops.
On-premise infrastructure adds another layer of strain with costly upgrades, brittle customizations, and growing security exposure from outdated components. Meanwhile, scaling for demand spikes or product launches becomes a guessing game, with systems that can’t flex when it matters most.
What businesses need isn’t a patchwork environment, but a platform built for real-time decisions, built-in scalability, and unified operations. That’s what Microsoft Dynamics 365 Business Central delivers.

Migrating to Dynamics 365 Business Central vs. Legacy ERP Systems
Many SMBs today are running on legacy ERP systems or disparate software that can hold back growth. In contrast, Microsoft Dynamics 365 Business Central represents a modern, cloud-based solution aligned with today’s business needs. The differences between Dynamics 365 Business Central and older ERP systems are significant:
- Modern Cloud Architecture vs. Outdated On-Premises:
Legacy ERPs often run on-premises servers that require continuous maintenance, manual updates, and costly infrastructure. This can consume IT resources with tasks like backups, patching, and troubleshooting, distracting from strategic projects. Dynamics 365 Business Central, being cloud-based, offloads those responsibilities to Microsoft. SMBs that adopt a cloud-first ERP approach “divest most of the responsibilities of disaster recovery planning, data management, patching, updating” to the cloud vendor, freeing up valuable IT talent for more important objectives.
- Continuous Innovation vs. Stagnation:
Older ERP software may be several versions behind or even at end-of-life with no new features. In fact, a quarter of distributors reported their growth was hindered by limitations of their legacy ERP – some were using systems so outdated that the software was no longer supported by the vendor. By switching to Dynamics 365 Business Central, companies ensure they are always on the latest technology. Microsoft rolls out innovations (AI, machine learning, advanced analytics, process automation, etc.) directly into Dynamics 365 Business Central on an ongoing basis. Each update can bring new capabilities that legacy systems simply can’t offer.
- Unified Platform vs. Siloed Applications:
Dynamics 365 Business Central is designed as a unified suite of ERP and CRM applications that work together, providing a 360° view of the business. All departments – from accounting and supply chain to sales and customer service – share data on one platform. Legacy environments, on the other hand, often consist of separate, siloed systems (or a patchwork of spreadsheets and software) that don’t talk to each other. This leads to duplicate data entry, inconsistent information, and difficulty gaining insights. With Dynamics 365 Business Central, SMBs get a centralized source of information across the company, which improves visibility and decision-making. Employees can access real-time operational and financial data in one place, enabling informed and timely choices.
- Better Integrations and Connectivity:
Legacy ERPs frequently lack easy integration with modern tools like e-commerce platforms, third-party logistics, or advanced analytics, especially if they predate APIs. In contrast, Dynamics 365 Business Central’s cloud nature and use of modern standards make integrations far easier. As mentioned, it connects naturally with Microsoft’s own products and supports a range of third-party connectors via AppSource. This means an SMB can readily extend Dynamics 365 Business Central with industry-specific add-ons or integrate it with their website, warehouse systems, etc., something that might be prohibitively complex with an outdated ERP.
- User-Friendly, Familiar Interface:
Many older ERPs have clunky interfaces that require extensive training to use. Dynamics 365 Business Central, however, features an intuitive, modern interface aligned with other Microsoft products that users know (e.g., Office 365). Employees often find it easier to navigate and adapt, which improves productivity. Moreover, Dynamics 365 Business Central offers customizable dashboards and role-based views, whereas legacy software might not easily adapt to individual workflows. This ease-of-use can reduce the change management pain when migrating.
- Scalability and Futureproofing:
An SMB running a legacy ERP might find that growth is constrained – perhaps the old system can’t handle increased transaction volume, additional users, or new business models without significant cost. Cloud-based ERP on Dynamics 365 Business Central offers virtually unlimited scalability. You can add more storage, users, or processing power on demand. Importantly, moving to Dynamics 365 Business Central also positions a company for the future; as one cloud ERP adopter put it, after switching, they no longer worry about outgrowing their system or lacking data when they need it. In contrast, the fear of “pushing a legacy ERP to its limit” is a common concern that disappears with a robust cloud ERP in place.
