If your system is not listed, we will evaluate it during the assessment and define the safest, most cost–effective route to Business Central while preserving essential data and reconciling balances accurately.
Our BC MIGRATION Framework
Free Assessment
We review objectives, current systems, customisations, data volumes, reporting needs and processes. Then we recommend the best migration or re implementation path.
Scope & Data Preparation
We agree the scope including companies, modules and history depth. We cleanse, map and template your master data and opening balances to accelerate test cycles.
Convert Extensions & Customisations
Where applicable, we convert customisations to Business Central extensions and prepare your environment for a smooth transition.
Test Migrations
We run staged test migrations in sandboxes, validate totals and transactions and involve key users early so adoption starts before go–live.
Hypercare & Optimisation
Post go live, we stabilise, fine tune, train and optimise dashboards, workflows and approvals. Then we hand back a system you can confidently scale.

Frequently Asked Questions
Can we migrate directly from NAV to Business Central online?
In most cases, you upgrade to a supported Business Central version, convert customisations to extensions and then move online. We handle the steps end to end.
How is data moved securely?
We use secure, audited pipelines and follow best practice for identity, access, encryption and cut over. This avoids risky manual moves.
What data from GP will transfer?
Master data, fiscal periods, accounts and segments mapped to Business Central dimensions plus selected transactional history as agreed.
Will historical transactions be retained?
Yes, subject to scope and quality. Many customers bring recent years of transactional history and keep older detail in an accessible archive.
How much downtime should be expected?
Minimal. We plan test cycles, rehearsal cut overs and weekend switchover where appropriate to reduce impact on operations.
