Legacy ERP Migrations

Move from outdated systems to modern, cloud-first Dynamics 365—securely, efficiently, and with zero business disruption.

Legacy platforms slow growth, increase risk, and limit innovation. Magnetic D365 delivers structured, low-risk migration paths from aging ERP systems to Microsoft Dynamics 365, helping your organization modernize with confidence.

Smooth, Secure, and Strategy-Led Migration to Dynamics 365

Legacy ERP systems limit scalability, require costly maintenance, and slow down decision-making. Magnetic D365 delivers a proven, strategy-led migration approach that replaces outdated systems with a modern Dynamics 365 platform—reducing operational risk, protecting critical data, and enabling future-ready performance. Our team ensures your migration is executed with precision, transparency, and minimal disruption to your business.

Whether you’re migrating from Great Plains, Navision, Solomon, Lawson, or another legacy platform, we ensure a predictable, low-risk transition.

Organizations migrate from legacy ERP systems to Dynamics 365 to achieve benefits such as:

 

Reduced Operational Risk

Protect your business from the risks associated with outdated, unsupported ERP systems.

Improved Data Quality & Visibility

Clean, structured, and modernized data that supports real-time reporting and better decisions.

Streamlined Processes & Automation

Replace manual, outdated workflows with modern, automated processes built into D365.

Lower Total Cost of Ownership

Reduce IT spend by eliminating custom code, hardware requirements, and costly legacy support.

A Structured, Proven Approach to Legacy ERP Migration

A successful migration requires more than technical expertise — it requires a phased, strategy-led approach that minimizes risk, protects data integrity, and ensures your new Dynamics 365 environment is fully aligned with your current and future business needs. Our methodology delivers clarity, predictability, and confidence at every stage.

S

Initiate & Assess

We begin with a thorough review of your legacy system, identifying risks, dependencies, integrations, and technical debt. This phase establishes scope, timelines, migration readiness, and project governance.

Discovery & Fit/Gap

We map your legacy processes, data structures, and business requirements to Dynamics 365 capabilities. The goal: determine what can be modernized, what must change, and what requires redesign.

Design & Modernization

Your future-state solution is designed designed using Microsoft Dynamics 365 best practices – including process optimization, integration strategy, data modeling, and security. We focus on reducing customizations and improving long-term maintainability.

Migration Build

We construct your environment, configure D365, modernize integrations, clean and transform data, and prepare everything for validation. This is the technical engine of the migration.

Validate & Train

End-to-end testing confirms data accuracy, process usability, system performance, and integration reliability. Meanwhile, users are trained through role-based, hands-on enablement activities.

Go-Live & Stabilization

We execute the migration cutover, monitor system performance, support users, and resolve issues quickly. The focus is stability, adoption, and ensuring your organization is confident in its new platform.

Frequently Asked Questions About Legacy ERP Migrations

How long does a typical legacy ERP migration to Dynamics 365 take?

Most migrations take 4–12 months, depending on data volume, customizations, integrations, and business complexity. We begin with an assessment to determine your timeline and provide a clear migration roadmap.

What legacy ERP systems do you have experience migrating from?

We have extensive experience migrating organizations off Great Plains, Navision, Solomon (SL), Lawson, SAP, Oracle, AS/400, and many industry-specific ERP platforms. Our team understands the unique challenges and data structures of older systems.

Will we lose any data during the migration?

No. Our migration approach prioritizes data preservation, cleansing, and validation. We perform multiple rounds of test migrations to ensure data accuracy before go-live.

How much downtime should we expect during cutover?

Most organizations experience minimal downtime, typically a weekend or planned maintenance window. We design a cutover plan that avoids operational disruption.

Can we migrate to D365 without replicating all our legacy customizations?

Yes — and in most cases, you shouldn’t replicate them. Dynamics 365 offers modern capabilities that replace many legacy customizations. We help you adopt best practices and reduce technical debt.

How do you handle integrations with other systems during a migration?

We review all existing integrations, identify modernization opportunities, and rebuild them using current best practices, such as Azure Integration Services, Power Platform, or API-based connectivity.

Will our team receive training on the new system?

Absolutely. We provide role-based, hands-on training tailored to how your people actually work. Training is integrated into validation cycles to support adoption and confidence.

What makes Magnetic D365 different from large consulting firms?

You get senior-level expertise without inflated enterprise consulting rates. Your migration is led by former Microsoft professionals who bring depth, speed, and clarity — not junior resources learning on the job.
