Dynamics NAV / Navision to Business Central Historical Data Migration
Moving from Dynamics NAV / Navision to Business Central does not mean useful accounting history has to remain trapped in the legacy system. Ledger to Cloud specialises in extracting, restructuring, mapping and reconciling historical finance data around the destination design agreed with your implementation partner.
Dynamics NAV / Navision history, rebuilt around the Business Central design.
Dynamics NAV / Navision to Business Central is not just an export and import.
Dynamics NAV / Navision history can include allocation and transaction detail that is easy to lose if a migration is scoped only around opening balances. The harder question is how that accounting history should fit the structure designed for Business Central.
Understand what is actually there
- Detailed nominal ledger transactions
- Customers, suppliers and allocations
- VAT rates, amounts and references
- Foreign-currency context where used
- Departments / analysis structures where used
- Bank, control-account and historical reporting data

Fit the agreed future-state design
- Destination Chart of Accounts
- Company / legal-entity structure
- Dimensions and reporting analysis
- Customer and vendor records
- VAT/tax and currency treatment
- Agreed historical transaction structure
Historical data is useful for more than compliance.
The right amount of history depends on the business, but there are practical accounting reasons to consider more than a single opening-balance journal.
Retention without legacy dependence
Businesses often need to retain accounting records for several years. Keeping a retired finance system solely for read-only access can add cost and inconvenience. Where appropriate, migrating useful history reduces the need to jump between old and new systems.
Comparable reporting
Historical data in the new structure can support prior-year comparisons, margins, variances and trend analysis using the future reporting model rather than leaving older periods trapped in the legacy structure.
Mid-year continuity
ERP go-lives rarely wait for a perfect year end. Even when a business does not want years of history, the current financial year may need detailed transactions, aged receivables and payables, allocations, bank reconciliation context and supporting data for year-end or audit.
Plan the source extraction before Dynamics NAV / Navision is retired.
For our preferred extraction method, Jet Reports is normally used to expose detailed transaction data in a usable structure. Alternative routes can be considered where required.
Historical finance data scoped around what the business still needs.
Not every project needs every field from every year. We agree the useful history first, then design migration and reconciliation around that scope.
General ledger history
Detailed transactions, dates, references, descriptions, accounts and source identifiers where available.
Receivables & payables
Customer and supplier history, open items and allocation/application context where the source and destination support it.
Dimensions & analysis
Legacy reporting structures are reviewed against the future-state model instead of copied mechanically.
VAT / GST / tax
Rates, amounts and historical tax context are mapped where relevant rather than reduced to a single net ledger value.
Foreign currency
Currency information and source-rate context can form part of the scope, with destination behaviour reconciled rather than assumed identical.
Multiple entities
Each entity can be scoped and reconciled while the group standardises its Chart of Accounts, reporting dimensions and intercompany approach.
How we work alongside the Business Central implementation.
We take ownership of the historical accounting dataset while the implementation partner owns the destination implementation and future-state configuration.
Inspect
Understand source data, years, entities, volumes and reconciliation points.
Map
Translate accounts, analysis, contacts and tax into the agreed Business Central structure.
Restructure
Prepare history to fit the future-state design rather than preserving old structures by default.
Load
Process the agreed datasets using the import route appropriate to the implementation.
Prove
Compare key source and destination reports and document material differences or agreed treatments.
Multiple legacy systems can become one reporting structure.
For group projects, migration is an opportunity to harmonise the Chart of Accounts, dimensions, intercompany approach and VAT/GST/tax treatment while bringing entities from different finance systems into one ERP.
Mixed source systems
A group may be leaving Sage, Access, Dynamics NAV / Navision, Dynamics, Twinfield or other systems at the same time. Broad source-system experience helps normalise those different histories into a common destination model.
Current-year continuity
At minimum, bringing the current financial year together can prevent the group from splitting one reporting year across several legacy platforms and the new ERP.
Consolidated reporting
Historical and current data mapped into a common group structure can make cross-entity comparison and consolidated reporting considerably more useful.

Dynamics NAV / Navision to Business Central migration FAQs
Practical answers about the historical-data workstream.
Can you migrate detailed Dynamics NAV / Navision history into Business Central?
Potentially, yes. The exact history depends on source quality, volumes, the agreed Business Central design and the import routes available for the records in scope.
Is this the same as implementing Business Central?
No. Your Business Central implementation partner owns the destination implementation and future-state configuration. Ledger to Cloud specialises in the historical accounting data workstream around that design.
How do you extract data from Dynamics NAV / Navision?
For our preferred extraction method, Jet Reports is normally used to expose detailed transaction data in a usable structure. Alternative routes can be considered where required.
Can Dynamics NAV / Navision analysis structures be mapped into Business Central?
Yes, where appropriate. We review the source analysis against Business Central dimensions and the reporting model configured by the implementation team. The mapping should follow the future-state reporting design rather than assume a one-to-one copy.
Can you migrate multiple Dynamics NAV / Navision companies into Business Central?
Multi-entity history can be scoped entity by entity and mapped into the agreed company and legal-entity structure. This is also an opportunity to standardise group reporting, intercompany treatment and the Chart of Accounts where appropriate.
Do we need to migrate every historical year?
No. The right scope depends on statutory retention, reporting, audit and year-end requirements, go-live timing, data quality and how much reliance the business wants to retain on the legacy system. Even when older history is not required, the current financial year often needs more than opening balances.
Your implementation partner builds Business Central. We handle the historical ledger.
Bring us in before Dynamics NAV / Navision is retired so source extraction, future-state mapping and reconciliation requirements can be agreed early.
