Why Migrate from Dynamics GP to Business Central Online

Organizations move from Dynamics GP to Business Central to get off aging, server-based software before support ends in 2029 — while preserving their financial history and customizations. A staged migration gets you there with operational continuity intact, rather than betting the quarter on a single go-live. Most mid-market migrations take 9–18 months, so the time to plan is now.

Why Dynamics GP to Business Central Migration Is Harder Than It Looks

Most growing companies underestimate a GP-to-Business Central migration because they treat it like an upgrade. It isn’t. Moving Dynamics GP to the cloud touches your customizations, your integrations, and your books at the same time — and a mid-market IT team rarely has spare hands for that.

Financial Data Risk

  • Trial balance mismatches during migration
  • AR/AP and inventory inconsistencies
  • Risk to financial reporting and compliance
  • Lack of reconciliation checkpoints

Business Continuity Pressure

  • Downtime impacts billing and order processing
  • Disruption to financial close cycles
  • Critical systems must remain operational
  • Limited tolerance for business interruptions

Integration Complexity

  • Dependencies on banking, payroll, EDI systems
  • Third-party integrations require reconfiguration
  • Reauthentication of connectors and APIs
  • High risk of broken workflows post-migration

Customization & Cutover Risk

  • Legacy customizations not cloud-compatible
  • Extension conversion challenges
  • Poor cutover planning leads to disruption
  • Identity and access inconsistencies

The Netwoven Phased Modernization Framework

We prioritize operational continuity, MVP-first deployment, and iterative validation — modernizing in controlled stages rather than attempting wholesale transformation at go-live.

Initiation & Governance

  • Stakeholders, scope, success criteria, and decision rights are agreed up front, so the project has clear ownership from day one.

Discovery & Design

  • We assess your current environment, customizations, integrations, and data, then design the target state and migration path.

Migration Preparation

  • Environments, version upgrades, data mapping, and the migration runbook are built and dry-run before any production move.

Pilot Migration

  • A structured pilot moves real data into a controlled environment to surface defects, integration gaps, and process issues early.

Functional Testing & UAT

  • Business users validate processes and data against agreed acceptance criteria, with issues tracked to closure.

Cutover & Hypercare

  • A planned cutover with a rollback path, followed by post-go-live stabilization so the platform runs cleanly once it’s live.

Migration Scenarios We Support

We support multiple migration paths to Dynamics 365 Business Central Online:

Multi-Company Consolidation: Not every migration is a single environment. We regularly consolidate multiple Business Central companies into one Business Central Online instance — including Chart of Accounts rationalization, financial dimension alignment, and retaining archived legacy entities for audit access. It’s a common enterprise need and a core part of what we do.

On-premises Business Central clients often can’t jump straight to the current cloud version. Multi-hop upgrade paths are real and add complexity. We assess and execute the required version upgrades as part of migration preparation — handled inside the engagement, not billed back as a separate project.

01

  • BC version and SQL prerequisites
  • User roles and license allocations
  • Extensions and ISV dependencies
  • Power BI workspaces and reporting
  • Authentication and app registrations
  • Service accounts and domain changes

02

We run two structured pilots, not one. The first pilot identifies defects, integration gaps, and process issues. The second pilot validates that remediation is complete and confirms cutover readiness. By the time we move to production, the environment has been proven twice — not tested once and hoped through.

03

We set expectations up front, not after the contract is signed. Full de-duplication prior to migration is not assumed or guaranteed, but mutual effort is made to clean and rationalize data before go-live. Most competitors won’t say that publicly — we’d rather you know.

04

A clear boundary between migration and business transformation keeps your project predictable. Unless separately scoped, the following are out of scope for a standard migration engagement:

  • Business process redesign
  • Major AL / custom development
  • Full historical data migration
  • Transformation of non-BC systems
  • Long-term support beyond hypercare

FAQs

Is Dynamics GP being discontinued?

Yes. Microsoft stopped selling GP to new customers in April 2026. Mainstream support ends December 2029, and security updates end April 2031. GP keeps running after those dates, but without tax updates, fixes, or support.

Can I migrate from Dynamics GP to Business Central online?

Yes. We migrate Dynamics NAV and Dynamics GP to Business Central online, including master data, open transactions, and historical records. The work includes rebuilding old customizations as supported cloud extensions, which a straight upgrade can’t do.

We have a small IT team — is a migration partner overkill for a mid-market company?

No — it’s the opposite. The leaner your team, the more a failed migration costs you. We own the plan, the cutover, and the rollback, and we run the platform after go-live, so a Business Central online migration doesn’t pull your staff off their day jobs or stall a quarter.

Will I lose my financial history or customizations?

No — preserving them is the point. We reconcile balances and validate data before go-live, and we re-engineer C/AL customizations as AL extensions so they survive future Microsoft updates. Finance signs off before cutover.

How long does a Dynamics 365 Business Central online migration take?

It depends on your data volume, the number of customizations, and your integrations. Our assessment gives you a fixed scope and timeline before any migration work starts, so you’re not committing to an open-ended project.

How much does a Business Central online migration cost?

Netwoven prices migrations on a custom-quote, outcome-based model — cost depends on your environment, complexity, and support needs. Engagements are fixed-scope, so the cost is predictable. Some Microsoft-aligned engagements may qualify for Microsoft funding. Request a custom quote tailored to your environment.

How do you minimize downtime during cutover?

We plan the cutover on a defined window, run parallel testing first, and keep a rollback path ready. Day-one continuity for the general ledger and core operations is a requirement of the plan, not a hope.
