A build-to-order X++ migration toolkit that extracts, maps, stages and reconciles legacy ERP data into Dynamics 365 F&O. ECOSIRE builds it for your source system after a scoping call and fixed quote. Built to order by ECOSIRE for Dynamics 365 F&O (build-to-order) — indicative price from $1499.00 USD; request a quote for a scoped proposal.
Replacing a legacy ERP with Dynamics 365 Finance and Supply Chain Management is rarely blocked by the finance design. It is blocked by data.
There is no supported conversion path from a legacy platform into F&O. The Data management framework expects records that are already shaped like F&O data entities, backed by valid customer groups, item model groups, posting profiles, ledger dimensions and number sequences. A legacy extract has none of that. It has free-text payment terms, a chart of accounts nobody else has ever seen, a decade of open transactions, item codes that carry meaning in the last three characters, and a set of fields the finance team insists are critical but which have never been mapped to anything.
So every migration project quietly rebuilds the same plumbing: extract scripts, a mapping spreadsheet that drifts the moment two people edit it, a staging database, a load sequence discovered by trial and error, and a reconciliation pack assembled by hand the night before go-live. That work is expensive, it is repeated at every trial load, and it produces nothing the business can see on a demo screen.
This accelerator is that plumbing, built for your migration.
The accelerator ships as an X++ extension model deployed alongside your existing F&O code. Nothing is overlayered. Logic sits in Chain of Command wrappers, event handlers and new tables inside a dedicated model, so it moves cleanly through platform updates and can be retired after cutover without unpicking your production configuration.
We build adapters against the source you are actually leaving. Depending on what your scoping call establishes, that is a direct read-only database connection, a REST or XML-RPC client, or a governed file drop from an extract your incumbent team produces. Each adapter is versioned, re-runnable, and writes into staging with a run identifier so you can compare two extracts taken a week apart. Common source shapes we build for include SAP tables, Odoo models, QuickBooks company files and older on-premise Dynamics installations, but the adapter is written to your schema, not to a generic template.
Mapping tables live in F&O as configuration: source value, target value, effective legal entity, transformation rule and an owner. Finance edits customer group and payment term mappings in a form with lookups against the real F&O reference data, so an invalid target cannot be saved. Every mapping is exportable and importable through a Data management framework package, which means the same mappings promote from your development environment to your sandbox and then to production without retyping.
Raw source rows land in staging tables in their original shape. Transformation runs as a separate step under the SysOperation framework so it can be executed in batch, restarted, and traced. Records that fail validation are not silently dropped: they are flagged with the rule that rejected them, grouped by error class, and exposed in a work-list form so a data owner can fix the mapping and re-run only the failures.
The accelerator drives standard DMF definition groups rather than writing to tables directly, so every load respects F&O validation, number sequences and posting logic. It sequences the dependency chain for you: legal entities and ledger setup, financial dimensions and dimension combinations, main accounts, customers and vendors, released products and product masters with their dimensions, on-hand quantities, open sales and purchase orders, open customer and vendor transactions, fixed assets with accumulated depreciation, and trial-balance opening journals. Loads are scheduled as batch jobs so an overnight trial migration runs unattended.
This is the part that decides whether the business signs the cutover. The accelerator generates comparison reports directly from the loaded F&O data against the extracted source totals: trial balance by main account and financial dimension, aged customer and vendor balances by bucket, inventory quantity and value by item and warehouse, open order value, and fixed asset net book value. Each report shows source total, F&O total, variance, and a drill-through to the specific records making up the difference. Reports are stored per run, so the migration lead can prove that trial load three is better than trial load two.
A cutover control form tracks each load step with its state, run time, record counts and the person who signed it off. Delta runs pick up records changed in the source after the main extract, which is what makes a short freeze window possible instead of a weekend-long one. Where a customer is also standing up Dataverse or Power Platform surfaces, the accelerator can hand off master data through Dual-write once the F&O side is stable.
This is built for organisations mid-programme on an F&O implementation who have realised that data conversion is the critical path, and for implementation partners who want the conversion mechanics handled while their consultants focus on process design. It suits multi-legal-entity groups migrating in waves, where the same mappings and reports must be reused for each entity going live.
It is not a replacement for a data owner. Somebody in your finance and supply chain teams has to decide what a legacy customer group becomes in F&O. The accelerator makes that decision cheap to record, easy to change, and impossible to lose.
Scoping call. We walk through your source system, the legal entities in scope, the data domains you need converted, how much transactional history you want to bring across, and your LCS and environment topology. We ask to see a sample extract or a schema dump.
Fixed quote. You receive a written scope listing the adapters, mapping domains, load sequences and reconciliation reports we will build, with a fixed price and a delivery window. Nothing starts until you accept it.
Build. ECOSIRE develops the model in a development environment on the same platform version as your target. Work is committed to an Azure DevOps repository — yours if you provide access, ours if you prefer to receive the source at handover.
Install in test. We deliver a deployable package for your sandbox. We install it, configure the mapping tables with your team, and run a full trial load against real extracted data so you see actual reconciliation numbers, not a demo dataset.
Production. After your sign-off, the same package is promoted through your LCS pipeline to production. We support your cutover run.
Support window. A defect-fix window follows go-live, covering the delivered functionality against the F&O version it was built for.
Lead time is typically one working week from accepted quote to test install, driven mostly by how many source domains are in scope and how quickly extract access is granted.
There is no download button. Nothing here is pre-built and waiting on a shelf; the value of this product is that the mapping library and adapters match your source schema, which is only knowable after we look at it. There is no free trial, because the artefact does not exist until we build it for you. If you need to evaluate our approach first, ask for a scoping call and we will walk you through the reconciliation report design before you commit.
A short call to confirm the workflow, your platform version and where the integration boundaries sit.
You receive a written scope and a fixed price. Nothing is built until you approve it.
We develop against a copy of your configuration and test it there. Typically two to four weeks.
We install on your instance, hand over the source, and include two weeks of go-live support. Defects in the code we deliver are fixed free of charge.
Owns a go-live date that keeps slipping because every trial load turns into a fortnight of manual data wrangling. This gives each load a repeatable sequence, a restart point and a reconciliation pack, so trial loads become a scheduled batch job instead of a project in themselves.
Cannot sign off a cutover on the promise that the data looks right, because the audit trail has to survive year-end scrutiny. The trial balance, aged AR and AP and fixed asset reports show source-to-F&O variance line by line with drill-through, so sign-off is based on numbers rather than assurances.
Spends the early phase writing throwaway extract scripts and hand-sequencing DMF jobs instead of configuring the solution. The accelerator supplies the adapters, staging layer and dependency-ordered orchestration as maintainable X++ in a clean model, leaving time for the design work that actually needs a consultant.
