Dynamics 365 migration from AX is one of the most significant infrastructure decisions a mid-size or enterprise business can make, and getting it right the first time matters. Microsoft Dynamics AX — including AX 2009, AX 2012 R2, and AX 2012 R3 — reached end of mainstream support, leaving organisations exposed to security gaps and blocked from accessing modern cloud capabilities. SchwettmannTech helps businesses in the UAE, UK, India, Saudi Arabia, and across Europe move their ERP operations to Dynamics 365 Finance and Operations with precision, controlled timelines, and minimal disruption to daily business activity.
What our Dynamics AX to D365 migration covers
- Pre-migration assessment and gap analysis: We audit your existing AX environment — data structures, custom code, integrations, and business processes — and produce a detailed migration readiness report that identifies risks before any technical work begins.
- Data migration and cleansing: Historical financial data, inventory records, customer and vendor master data, open transactions, and chart of accounts are extracted, validated, cleansed, and loaded into Dynamics 365 Finance and Operations using Microsoft’s data management framework and proven ETL tooling.
- Custom code and ISV solution migration: Legacy AX customisations built in X++ are reviewed, refactored where necessary, and rebuilt as extensions in D365 to comply with Microsoft’s no-overlay model, protecting your investment in future upgrades.
- Integration re-architecture: Existing integrations with CRM systems, warehouse management platforms, payroll providers, banking interfaces, and third-party portals are redesigned using modern APIs, Azure Logic Apps, or Power Automate to replace legacy AIF-based connections.
- User acceptance testing and cutover planning: We design structured UAT cycles with your finance, supply chain, and operations teams, followed by a formal cutover plan that defines go-live steps, fallback procedures, and a parallel-run strategy where required.
- Post-go-live support and hypercare: SchwettmannTech provides dedicated post-migration support covering bug resolution, performance tuning, and user query management for a defined hypercare period, typically four to eight weeks after go-live.
Why businesses in the UAE, UK, India, and Saudi Arabia choose SchwettmannTech
- Microsoft-certified expertise: SchwettmannTech holds Microsoft Solution Partner status for Business Applications. Our 120+ consultants include certified functional architects, technical developers, and project managers with hands-on Dynamics AX and D365 Finance and Operations experience.
- Global delivery with regional knowledge: With offices in India, Germany, UAE, and Cyprus, we understand the local regulatory requirements that affect your migration — including VAT compliance for UAE and Saudi Arabia, Making Tax Digital considerations for UK businesses, and GST structures for Indian entities.
- Proven enterprise client base: We have delivered complex ERP transformations for clients including B.Braun and Deutsche Telekom. Our team is accustomed to working within strict change management frameworks, enterprise security policies, and multinational data governance requirements.
- Fixed-scope and agile delivery models: Depending on the complexity of your AX environment, we offer both fixed-scope contracts with defined deliverables and costs, and phased agile approaches that allow scope adjustment as requirements become clearer during discovery.
- Knowledge transfer built into delivery: We do not create dependency. Every migration engagement includes structured knowledge transfer so your internal IT team or finance administrators can operate and configure D365 Finance and Operations independently after go-live.
Our Dynamics AX to D365 migration process
- Discovery and current-state assessment: We spend two to four weeks analysing your AX environment, interviewing key stakeholders, mapping business processes, and documenting integration points. This phase produces the foundation for accurate project scoping and timeline planning.
- Solution design and project planning: Using the discovery output, our architects design the target D365 Finance and Operations configuration, define the data migration strategy, and produce a project plan with milestones, resource assignments, and a risk register.
- Environment build and configuration: We provision your D365 environment, apply base configuration aligned to your chart of accounts, legal entities, currencies, and fiscal calendars, and begin building any required extensions or integrations in a development environment.
- Data migration and integration development: Data migration runs in iterative cycles — typically two to three mock migrations — allowing your finance team to validate data accuracy before final cutover. Integration development and testing runs in parallel during this phase.
- User acceptance testing: Your business users execute test scripts across finance, procurement, inventory, and reporting scenarios. Defects are logged, prioritised, and resolved through a structured issue management process. Sign-off at this stage gates the cutover decision.
- Go-live and hypercare: We execute the production cutover according to the agreed plan, monitor system stability in the days immediately following go-live, and provide direct access to our support team during the hypercare period to address any issues quickly.
Pricing and cost
The cost of a Dynamics 365 migration from AX depends primarily on the size of your AX environment, the volume and complexity of custom code, the number of integrations, and the data volume involved. For small to mid-size businesses migrating from AX 2012 with limited customisation, project fees typically range from £60,000 to £150,000 (or equivalent in USD, AED, or INR). For larger enterprise environments with extensive X++ customisation, multiple legal entities, and complex integrations, project costs commonly fall between £200,000 and £500,000 or more. Dynamics 365 Finance and Operations licensing is separate and priced by Microsoft per user per month, starting from approximately £150 per full user. SchwettmannTech provides a detailed, fixed-scope cost estimate following the discovery phase so there are no unexpected charges mid-project.
Frequently asked questions
How long does a Dynamics 365 migration from AX typically take?
Most AX to D365 Finance and Operations migrations take between six and eighteen months from discovery to go-live. Smaller AX environments with minimal customisation may complete in six to nine months. Large enterprise environments with multiple legal entities, heavy customisation, and complex integrations typically require twelve to eighteen months. SchwettmannTech provides a timeline estimate after completing the discovery and assessment phase.
Can we keep our AX customisations when migrating to D365?
Some AX customisations can be carried forward, but they must be rebuilt as extensions in D365 rather than overlays. Our technical team reviews all existing X++ code during discovery, identifies what can be refactored, what can be replaced by standard D365 functionality, and what must be rebuilt. This analysis is included in the project scoping phase.
Will our historical data be available in D365 after migration?
Yes. SchwettmannTech migrates your key historical data — including closed financial periods, customer and vendor transaction history, and inventory balances — into D365. The volume and depth of historical data migration is agreed during the scoping phase, balancing business requirements against migration complexity and cost.
Do you support businesses outside your office locations?
Yes. While SchwettmannTech has physical offices in India, Germany, UAE, and Cyprus, we deliver projects for clients across the UK, Saudi Arabia, wider Europe, and other regions through a combination of remote delivery and on-site engagement where necessary. Our project management and communication processes are designed for distributed teams and time zones.
What happens if something goes wrong after go-live?
SchwettmannTech includes a structured hypercare support period in every migration engagement. During hypercare, your organisation has direct access to our project team for rapid issue resolution. After the hypercare period, we offer ongoing managed support contracts covering Dynamics 365 Finance and Operations administration, updates, and development work on a retainer or time-and
