If your business is still running on Dynamics NAV (Navision), Dynamics AX, Microsoft Great Plains, or Dynamics SL, the pressure to move is already here, not on the horizon.
Microsoft has phased out Mainstream Support for all versions of Dynamics NAV, meaning no new features, functional updates, or non-security fixes are being issued. The remaining Extended Support windows are closing fast: NAV 2016 expired in April 2026, NAV 2017 ends in January 2027, and NAV 2018 follows in January 2028. Once Extended Support ends, your system receives no further security patches, leaving your business exposed.
Microsoft Dynamics 365 Business Central is the modern, cloud-based successor designed to replace these systems. Advantage Business Systems helps UK businesses migrate from legacy ERP to Business Central with a structured, low-disruption approach, protecting your data, your processes, and your people throughout the transition.
Remove your reliance on unsupported ERP software before Extended Support ends. Protect your business from security risk, compliance gaps, and rising legacy maintenance costs.
Replace your old ERP with a single cloud-based system covering finance, operations, purchasing, stock management, projects, and reporting, all working together in real time.
We manage the transfer of your master data, financial records, and transactional history from your legacy ERP into Business Central, accurately, securely, and with a full audit trail.
Leave behind slow legacy reporting and manual data pulls. Business Central delivers live dashboards, real-time financial data, and Power BI integration as standard.
Cloud-based Business Central removes the burden of on-premise servers, manual upgrades, and the increasing IT cost of keeping ageing ERP infrastructure running and patched.
Business Central scales with your business, supporting more users, entities, and complexity, with Microsoft continuously developing new features and integrations.
We review your Navision, AX, Great Plains, or Dynamics SL environment, assessing your processes, data, customisations, and integrations, to define the right migration approach.
We create a structured migration plan covering data mapping, system design, testing, and go-live timeline, keeping disruption to your operations to a minimum.
We extract, cleanse, and migrate your master data, open transactions, and historical records from your legacy ERP into Business Central, securely and accurately.
We configure Business Central around your finance, operational, and reporting requirements, not a generic setup, but one built around how your business works.
We train your team on the new system and support adoption so your people are confident and productive from day one, rather than left to find their own way after go-live.
Migration is the beginning, not the end. We remain your long-term Business Central partner — supporting, optimising, and developing your solution as your business grows and changes.
Migrating from a legacy ERP is one of the most significant system changes your business will go through. Getting it right requires more than technical knowledge, it requires a partner who understands your business, manages the process carefully, and supports you well beyond go-live.
Advantage is a Microsoft Solutions Partner and Cyber Essentials certified. We have helped UK businesses migrate from Dynamics NAV, Dynamics GP, and other legacy Microsoft ERP systems into Business Central, delivering structured, secure ERP modernisation backed by Microsoft best practice and hands-on implementation experience.
It is the right time to migrate if you are:
We needed a Dynamics partner. Advantage stood out with clear communication and a simple, fixed package that made everything straightforward.
The partnership with Advantage has been transformative, helping us use Dynamics 365 fully and demonstrate clear, measurable impact for fundraising.
Our initial conversation with Advantage was exceptional. They understood our needs and gave us confidence as a long-term partner for implementation and support.
We’re delighted with the CRM integration Advantage delivered, on time and within budget, with excellent communication and responsiveness throughout. Highly recommended.
If you are running a legacy Microsoft ERP system and want to understand your options, timeline, and migration path to Business Central, we would be happy to help.
