A purpose-built ETL platform for Dynamics 365 to Oracle Fusion migration — F&O, Business Central, and Customer Engagement. Main Account / dimension crosswalks, Dataverse extractors, FBDI/HDL emitters. 50–70% faster than consultant-led programmes.
Most Dynamics 365 to Oracle Fusion migrations fail in the Main Account collapse, X++ extension inventory, and Power Platform re-engineering — not in extract or load.
Dynamics 365 customers carry years of accumulated customization across two very different technical estates: D365 Finance & Operations sits on the AX/Axapta lineage with X++ extensions in the AOT, custom Tables, modified Forms, Lifecycle Services deployment artifacts, and BYOD export jobs; D365 Customer Engagement sits on Dataverse with custom entities, business rules, plug-ins, and Power Platform flows. Consultant-led migrations spend the first 4–6 months just cataloguing what exists across both environments. By the time real ETL work starts, budget and timeline are already half-consumed.
Syntra ETL inverts the sequence. Pre-built extractors for every standard D365 F&O entity (VendTable, CustTable, InventTable, MainAccount, LedgerJournalTrans) and every Dataverse table (Account, Contact, Opportunity, Salesorder) mean week-one extraction. A discovery engine that crawls the AOT, the Lifecycle Services package catalog, the Dataverse solution registry, and the Power Platform connector list produces a complete customization inventory in days, not months. The conversation that consumed the first 4–6 months of every traditional project now happens in week three, with hard evidence on the table.
Whether you're migrating F&O Finance only, both F&O and CE, or running the Business Central pattern where mid-market subsidiaries are consolidating up to enterprise Oracle Fusion, the same engine handles the workflow — with the same reconciliation rigor and the same audit trail.
And how the Syntra ETL platform addresses each one — before they consume your timeline.
D365 F&O's MainAccount + dimensions model collides with Fusion's fixed 6-segment COA. Syntra ETL's analyser surfaces which dimensions drive material splits, proposes a Fusion-fit segment design, and routes the rest to DFFs, PPM dimensions, or analytical archive.
Discovery crawls the AOT, SysModelStores, Lifecycle Services package catalog. Every X++ extension, custom Table, modified Form, and Class extension gets a Fusion-equivalence recommendation: native, Page Composer, VBCS, OIC, or retire. Typical outcome: 50–70% retired outright.
Dataverse's entity-relationship model (Account, Contact, Opportunity, Salesorder) translated to Fusion Sales/CX or extracted to operational data store. Many-to-many relationships, owning-team security, and audit history all preserved.
Power Platform asset inventory, business-value classification, and Fusion-equivalent rebuild plan (OTBI, BI Publisher, OIC, VBCS). 40–60% of Power Platform assets retired during cleanup; only the critical ones get rebuilt.
Every Dual-Write integration, Business Events subscription, virtual entity, and Common Data Service integration gets re-pointed to Oracle Integration Cloud (OIC) — with cut-over orchestration so upstream/downstream systems never lose a beat.
Decades of LedgerJournalTrans and GeneralJournalAccountEntry don't all need to land in Fusion. The archival path puts cold periods in queryable cloud storage with auditor-grade access — keeping Fusion lean and license costs predictable.
A repeatable, governed workflow built for D365's particular complexity. Typical multi-module timeline: 12–18 weeks.
Discovery engine crawls the AOT, Lifecycle Services package catalog, Dataverse solution registry, Power Platform connector list, and BYOD export jobs. Output: a complete customization inventory, Main Account / dimension usage analysis, and a sized migration assessment with risk register.
Main Account + dimensions → COA segment design, vendor/customer/item de-duplication rules, DFF routing decisions, employee/department/cost-center mappings. Reviewed and signed off by finance, HR, and SCM functional leads. X++ retire/replace decisions logged.
Pre-built D365 F&O extractors pull LedgerJournalTrans, GeneralJournalAccountEntry, VendTable, VendInvoiceJour, CustTable, CustInvoiceJour, InventTable, FixedAsset; Dataverse extractors pull Account, Contact, Opportunity, Salesorder. Output staged as Parquet with row hashes and partition manifests.
Crosswalks applied, Main Accounts collapsed to Fusion COA, DFFs populated, FBDI/HDL/REST payloads generated, validated against Fusion 26x release templates. Errors surfaced locally with row-level diagnostics.
FBDI ZIPs and HDL bundles submitted to Fusion ESS, monitored to completion, reconciled at row, sum, and hash level. In parallel, critical OTBI and BI Publisher reports rebuilt and validated against D365 / Power BI equivalents.
1–2 close cycles in parallel (D365 + Fusion), deltas captured and replayed, reconciled to the cent, sign-off pack issued. D365 moves to archive-only; production traffic now flows to Fusion.
No more bespoke OData queries or BYOD pipelines. Just configure scope, run, reconcile.
MainAccount, LedgerJournalTrans, LedgerJournalAC, GeneralJournalAccountEntry, GeneralJournalEntry, DimensionAttributeValueCombination. Full dimension context preserved, period-by-period reconciliation built in.
VendTable, VendInvoiceJour, VendInvoiceTrans, VendTrans, VendPaymJour. Open vendor invoice migration with full approval and payment-status context.
CustTable, CustInvoiceJour, CustInvoiceTrans, CustTrans, CustSettlement. Open customer invoice aging preserved, AR cleanup rules applied during extract.
InventTable, EcoResProduct, InventSum, SalesTable, SalesLine, PurchTable, PurchLine. Multi-site inventory, costing methods, BOM/route history all preserved.
G/L Entry, Customer, Vendor, Item, Sales Header, Purchase Header, Job Ledger Entry. Full NAV/BC schema extracted via Business Central API with company-level partitioning.
Account, Contact, Lead, Opportunity, Quote, Salesorder, Invoice, Incident, Activity. Many-to-many relationships, audit history, owning-team security all captured.
A typical Dynamics 365 to Oracle Fusion migration (D365 Finance & Operations or Business Central plus Customer Engagement, 5–10 years of history, 800GB–2TB source) runs 12–18 weeks with Syntra ETL versus 12–18 months with consultant-led approaches. Single-module projects (F&O Finance-only or BC-only) complete in 8–11 weeks. The acceleration comes from pre-built extractors for D365 F&O entities (VendTable, CustTable, InventTable, MainAccount, LedgerJournalTrans), Dataverse table extractors for CE (Account, Contact, Opportunity, Salesorder), governed crosswalks for Main Account → Fusion COA segment translation, and FBDI/HDL emitters validated against the current Oracle Fusion 26x release. Mixed-tenant scenarios where F&O lives on Dynamics 365 Finance and CE lives in Dataverse typically add 2–3 weeks to handle the cross-product reconciliation.
Customers migrate from Dynamics 365 to Oracle Fusion for four common reasons. First, M&A consolidation: when an Oracle-shop acquires a Microsoft-shop (or vice versa), one ERP usually wins, and at large enterprise scale Oracle Fusion's deeply integrated Financials/SCM/HCM/PPM suite typically wins on the global-standardisation criterion. Second, embedded AI: Fusion ships AI for anomaly detection in AP, predictive cashflow, intelligent matching, and supplier-risk scoring that D365 customers find missing or scattered across Power Platform add-ons. Third, manufacturing-scale SCM: F&O is competitive at mid-market but Fusion SCM dominates in process manufacturing, project-driven industries, and global multi-org consolidation. Fourth, talent and cost: D365 X++ developers are scarce and expensive; Oracle Fusion's quarterly-update model reduces the need for custom code entirely.
Syntra ETL supports Dynamics 365 to Oracle Fusion migration across the full D365 product family. D365 Finance & Operations (formerly AX/Axapta): General Ledger, Accounts Payable, Accounts Receivable, Fixed Assets, Cash and Bank, Inventory Management, Production Control, Procurement and Sourcing, Sales and Marketing, Project Management and Accounting, Human Resources (where bundled), Retail and Commerce. D365 Business Central (formerly NAV/Navision): all standard finance, sales, purchase, inventory, jobs, and manufacturing modules. D365 Customer Engagement (formerly CRM): Sales, Customer Service, Field Service, Project Operations, Marketing — all extracted from Dataverse. D365 Human Resources: extracted via Dataverse with full effective-dated history.
D365 F&O uses a Main Account + Financial Dimensions model: a single Main Account (e.g. 100150 — Cash) is combined with up to ten configurable financial dimensions (BusinessUnit, Department, CostCenter, ItemGroup, Project, etc.) to form a posting account string. Oracle Fusion uses a fixed 6-segment Chart of Accounts. Syntra ETL's mapping engine analyses MainAccount usage across LedgerJournalTrans and GeneralJournalAccountEntry, identifies which financial dimensions drive material reporting splits, and proposes a Fusion 6-segment design that preserves the material splits while collapsing redundant dimensions. Dimensions that don't make the cut route to Fusion DFFs, PPM dimensions, or analytical-only archives. Every mapping is reviewed and signed off by finance leads before any load runs.
X++ itself doesn't migrate — Fusion has no X++ runtime, no AOT, no Application Object Server. What Syntra ETL does is inventory every X++ extension, custom Table in the AOT, modified Form, Class extension, and Lifecycle Services deployment artifact in the source D365 F&O environment, classify each by business purpose, and produce a Fusion-equivalent recommendation: native Fusion functionality, Page Composer, Visual Builder Cloud Service (VBCS) extension, Oracle Integration Cloud (OIC) flow, or BI Publisher report. Customers typically find 50–70% of X++ extensions are redundant under Fusion's native capabilities and can be retired entirely. The remaining 30–50% get re-implemented in Fusion-native tooling — not translated line-by-line.
Power Automate flows, Power BI dashboards, and Power Apps don't carry over to Fusion's runtime. The Syntra ETL assessment phase inventories every Power Platform asset connected to your Dynamics 365 estate, classifies by business value, and proposes Fusion replacements. Power Automate flows that orchestrate D365 records become Oracle Integration Cloud (OIC) flows. Power BI reports against D365 Finance become OTBI dashboards or BI Publisher reports against Fusion. Power Apps front-end extensions become Visual Builder Cloud Service (VBCS) extensions or Fusion Page Composer customisations. Approximately 40–60% of Power Platform assets are deprecated as redundant during the inventory; the rest are rebuilt during migration so go-live includes the automation and reporting layer, not just the data.
Dataverse extractors use the Microsoft TDS endpoint (SQL-over-Dataverse) and the Web API in parallel, partitioning across business units, owners, and modifiedon date ranges. Soft-deleted records, audit history, and many-to-many relationship tables are captured along with the primary entity rows. The largest CE deployment our customers run is 280 million Account+Contact+Opportunity+Activity rows; extraction completes in 8–14 hours with throttling tuned to your Dataverse capacity. Outputs include hash signatures, manifest files with row counts per entity, and an audit log of every Web API call — ready for SOX, GDPR, and FINRA control evidence.
No. Syntra ETL's D365 F&O extractors connect through standard SQL Server read access to the F&O Azure SQL DB or via the BYOD (Bring Your Own Database) export pipeline, throttled to avoid contention with online users and Lifecycle Services batch windows. For very large F&O environments, extracts can be pulled from an export-replicated database to eliminate any production impact. Dataverse extracts (for D365 CE) use the standard Web API throttled within your service-protection limits. No D365 code changes, X++ modifications, AOT extensions, or LCS deployments are required for extraction.
