Delaying Your Legacy Migration is a Growing Liability

Legacy Dynamics environments don’t just fail at once; they erode quietly and eventually over time. However, these failing systems bring forth several risks, and some don’t show until it’s too late.

Integration Bottleneck

Legacy Dynamics wasn't built for a world of REST APIs, real-time data feeds, and cloud-native SaaS tools. Every new integration, whether it's payroll, CRM, e-commerce, or EDI, is just bolted on through custom middleware or manual exports.

Talent Drain

Mainstream and extended support windows for Dynamics GP, NAV, and AX have already closed or are closing fast. Running past end-of-life means no security patches, no compliance updates, and no vendor accountability if a vulnerability gets exploited.

Maintenance Trap

Fixing the already broken legacy tools consumes a budget that should be funding modernization and transformation. IT teams get stuck servicing a platform that will never scale, while the roadmap for AI, automation, and Copilot-ready data sits frozen.

Talent Drain

The consultants who understand Dexterity, X++, or classic NAV C/AL are retiring from their work because there aren’t many organizations still using these solutions. Every year, your bench of people who can actually troubleshoot your system shrinks, and the ones who remain command premium rates for increasingly fragile knowledge.

Legacy Microsoft Dynamics Solutions We Stabilize, Support, and Modernize

Dynamics GP

Dynamics GP runs on a segmented, on-premises architecture and was once the accounting backbone of mid-market organizations. With support for Great Plains ending between 2029 and 2031, businesses must modify these environments.

DynaSUM modernizes and migrates your operations from GP using Dexterity code, VBA customizations, and SQL views.

We replace outdated GP modules with standard Business Central capabilities and also rewrite the logic using AL extensions where customizations are required.

Dynamics NAV

The go-to ERP capability solution, Navision takes care of the finance, supply chain, and manufacturing processes.

Dynamics NAV is built on C/AL, and developers write C/AL code directly into the base objects; today, this creates a severe technical trap. Support for NAV is ending on 12th January 2028, and before that, you can hire DynaSUM experts to transition the processes to Business Central.

The advanced Business Central changes the deployment model to replace C/AL with AL extensions that work with the core application code, delivering automatic cloud updates to the system without breaking the custom logic.

Dynamics AX

Dynamics AX managed complex global financials, heavy manufacturing, and multi-entity supply chains at the enterprise level. AX environments demand massive on-premises server infrastructure, and maintaining them is gradually becoming more costly.

The X++ codebase allowed enterprises to customize the software so that it aligns with specific and rigid business rules, which has created fragmented databases and severe technical debt over the years.

Running AX today leaves your organization with a big security risk and limits the ability to scale. We transition your processes to Dynamics 365 Finance and Supply Chain Management while removing the on-premises burden and consolidating fragmented data.

Dynamics CRM

Legacy Dynamics CRM is also an on-premises solution, and it operates in complete isolation and fragments data into different datasets that cannot communicate.

The support for Dynamics CRM officially ended on January 13, 2026, and modernizing to Microsoft Dynamics 365 Customer Engagement (sales and customer service) is the only option you have today.

DynaSUM replaces status databases with connected CRM architecture, allowing your sales team to utilize AI-assisted selling, automate repetitive follow-ups, and work with real-time data.

The DynaSUM Methodology: Stabilize Today, Migrate Tomorrow

We treat legacy support and cloud transformation as one continuous engagement, offering assistance to run the existing systems until end of life while preparing for the migration process.

01.

Assess

Our experts assess your environment through a Legacy Modernization Upgrade Assessment to document customizations, integration dependencies, data quality gaps, and compliance exposure. We understand the gaps, pitfalls, and risks before making any migration decision.

02.

Migrate

Following zero-downtime data migration frameworks and phased cutover methodology, we migrate your data and platform. Our processes are built to protect transaction history and audit trails while ensuring continuity.

03.

Transform

The next step is Microsoft Dynamics modernization as we transform your existing on-premises footprint into cloud architecture operating on Dynamics 365 and Azure. The architecture we build is designed to work with a Copilot-ready data foundation, ensuring all future engagements and interactions are AI-powered.

04.

Manage

We manage the interim state through Interim Application Management, ensuring your legacy systems stay patched, monitored, and operational for the entire duration of the transition.

The DynaSUM Advantage: IT Transformation Powered by BPO Services

DynaSUM pairs technology modernization with offshore BPO accounting teams who operate their daily finance functions inside the legacy or transitional environment to ensure business continuity during the Legacy Microsoft Dynamics transformation and migration process, executed in four pillars: Operate, Reconcile, Absorb, and Scale.

We Operate accounts payable, accounts receivable, and general ledger tasks through a dedicated offshore finance team.

Our experts Reconcile month-end close processes on schedule, without considering where the migration process currently stands.

Our team will Absorb the operational load during cutover windows, so your finance team isn’t forced into testing and data validation on top of their day jobs.

We will also Scale the BPO team up or down as the platform stabilizes, without a separate hiring or vendor cycle.

FAQs

1. Is Microsoft still supporting Dynamics GP, NAV, AX, or CRM on-premises?

Support status varies by product and version;

Dynamics GP – ends between 2029 and 2031
Dynamics NAV – till the end of 2028
Dynamics AX – already ended in 2023
Dynamics CRM – available till January 2027.

DynaSUM can confirm your specific product’s support status and the risk window as part of the initial assessment.

2. Do we have to migrate to Dynamics 365 immediately to get support from DynaSUM?

DynaSUM provides direct support, patching, and administration for your current legacy environment independent of a migration decision. The assessment and roadmap come first, and we will build the migration timeline around your operational readiness.

3. How long does a legacy Dynamics to Dynamics 365 migration typically take?

Migration timeline depends on customization depth, data volume, and integration complexity. Our team will conduct a fit-gap analysis during the assessment phase to provide a specific, phased timeline for your environment rather than a generic estimate.

4. What happens to our custom code and integrations during migration?

Every customization process with DynaSUM is catalogued during the fit-gap analysis and evaluated against three paths;

Retire it if the functionality now exists natively in Dynamics 365
Rebuild it using modern extensibility frameworks
Bridge it temporarily during the transition.

5. How does the offshore BPO accounting team fit alongside our existing finance staff?

The BPO team operates as an extension of your in-house team, completing the transactional and operational finance work, including AP, AR, reconciliations, and month-end tasks, while working under the stewardship of your existing finance leadership, which defines and reviews.

6. What makes DynaSUM's approach different from a typical Microsoft implementation partner?

Most partners deliver the technology and leave operations for your team to manage. DynaSUM pairs the platform modernization with offshore BPO accounting teams who run your daily finance functions during the transition, so the migration doesn’t create an operational gap in the business it’s meant to improve.
