Six-layer microsoft dynamics nav migration reconciliation — opening balance, in-flight transactions, document chain, statutory submissions, parallel-run cumulative, cutover sign-off. Per company and consolidated. Signed by tax, audit, finance, operations and IT.
A NAV → Fusion migration that proves its loads pass per-record validation but cannot prove project-level reconciliation has no story for the audit committee, the external auditor or the first month-end variance investigation in Fusion.
Data validation is necessary but not sufficient. Per-load technical pass-criteria say 'the records that went in came out the other side'. They do not say 'the Fusion balance at go-live equals the NAV balance at cutover'. They do not say 'every in-flight Sales Order survived cutover with approval state and dimension context preserved'. They do not say 'the VAT return for the cutover quarter reconciles across NAV and Fusion outputs'. Those are the questions that finance, tax and audit ask when they assess whether the migration is actually done.
Syntra ETL's microsoft dynamics nav migration reconciliation framework is the umbrella discipline that answers those questions in writing. Six layers, each with its own pass criteria, each producing a signed evidence page, all bound into a single steering-committee-signed pack at cutover. Opening balance reconciliation proves the start state. In-flight transaction reconciliation proves the cutover boundary survived. Document-chain reconciliation proves the audit trail is intact. Statutory reconciliation proves the regulatory boundary survived. Parallel-run cumulative reconciliation proves Fusion is operationally trustworthy. Cutover sign-off binds it all.
Whether the engagement is a single-company NAV 2016 replacement in a German factory, a multi-region NAV 2018 estate across UK, Ireland and France with HMRC MTD and EU SAF-T obligations, or a Navision-era database merging into a multi-company Fusion ledger — the same six-layer framework runs, the same pass criteria apply, the same evidence pack ships.
Each layer answers a specific question that finance, tax and audit will ask at sign-off. Each produces its own signed evidence page.
Fusion GL TB at go-live equals NAV TB at cutover, per G/L Account, per period, in LCY and ACY, per company and consolidated. Pass criterion: zero delta. Sign-off: finance + audit.
Every open Sales Order, Purchase Order, production order, unposted journal at cutover survives in Fusion with header state, line state, approval state and dimension context. Pass criterion: 100% count + amount match. Sign-off: operations.
Sample n=50 Fusion AR/AP balances drilled back through migration evidence to originating NAV Sales/Purchase Invoice with supporting attachments. Pass criterion: every drill-back intact. Sign-off: audit.
VAT returns, MTD digital records, SAF-T per-country submissions, Intrastat declarations, GoBD GDPdU exports for cutover period generated from both NAV and Fusion outputs, reconciled. Sign-off: tax.
30–60 days of nightly delta reconciliation plus 1–2 month-end TB/aging/inventory reconciliations aggregated. Pass criterion: zero cumulative material variance. Sign-off: finance + IT.
Full evidence pack bound, signed by tax, audit, finance, operations and IT leads, then signed by steering committee on cover page. Sign-off: steering. NAV moves to read-only archive.
Reconciliation activities run in parallel with extract/transform/load, not as a final-stage afterthought. Each layer has its own milestones and gates.
Mapping evidence pack signed. Pass criteria for opening-balance reconciliation agreed with finance and audit in writing. Reconciliation engine configured for in-scope periods.
Opening-balance reconciliation and in-flight transaction reconciliation run on dress-rehearsal data. Variances investigated, mapping refined if needed, methodology locked.
Document-chain drill-back sampling methodology agreed with audit. Statutory submission output side-by-side methodology agreed with tax. Sample size and pass criteria documented.
Final opening-balance reconciliation and in-flight transaction reconciliation run on production data at cutover. Pass criteria checked. Layer 1+2 evidence pages signed.
Nightly delta reconciliation runs end-to-end. Cumulative parallel-run pack assembled across the window. Layer 5 evidence page signed at end of parallel-run window.
All six layers' evidence bound into the steering-committee microsoft dynamics nav migration reconciliation pack. PDF signatures applied. NAV moves to read-only archive. Migration formally closed.
The failure modes Syntra ETL prevents — every one of them seen on consultant-led NAV → Fusion projects that skipped or under-invested in the reconciliation discipline.
Without rigorous Layer 1 reconciliation, an unexplained variance shows up at first month-end close in Fusion. Multi-week scavenger hunt across both systems. Nobody can say if it is a Fusion variance or a migration artefact.
Without Layer 2, an open Sales Order from cutover Friday is missing in Fusion on Monday. Customer ships nothing. Operations escalation. Migration is blamed but evidence is unavailable.
Without Layer 3, the external auditor asks for the originating NAV Sales Invoice behind a Fusion AR balance, and the chain is broken. Audit qualifies. Insurance pressure follows.
Without Layer 4, the VAT return for the cutover quarter generated from Fusion differs from the NAV-side equivalent. HMRC or DE tax authority queries. Hand reconciliation under pressure.
Without Layer 5, NAV continues taking transactions during parallel run and drift accumulates undetected. By month-end, NAV and Fusion are materially out of sync.
Without Layer 6 binding everything together, steering committee has no single artefact to sign off on. Migration drifts in 'maybe complete' state for months.
Microsoft dynamics nav migration reconciliation is the broader project-wide discipline of proving that a NAV → Fusion migration is materially complete and correct across every domain that matters for audit, finance, operations, tax and supply chain. Where data validation is the per-load technical reconciliation, migration reconciliation is the umbrella framework that ties together opening-balance reconciliation, in-flight transaction reconciliation, document-chain reconciliation, statutory-submission reconciliation, parallel-run cumulative reconciliation and final cutover sign-off — all bound into a single signed evidence pack that closes out the migration with finance, audit and steering committee.
Data validation runs at the load level — for every batch of records pushed into Fusion, did the load succeed and do the post-load aggregates equal the pre-load aggregates. Microsoft dynamics nav migration reconciliation operates at the project level: do the Fusion balances at go-live equal the NAV balances at cutover, does every in-flight transaction (open Sales Orders, open Purchase Orders, unposted journals, in-flight production orders) survive cutover, do statutory submissions for the cutover period reconcile across both systems, does the document chain from a Fusion GL line back to the originating NAV Sales Invoice survive intact. It is the integrative discipline that finance and audit sign off on, not the per-load technical pass-criterion.
Six layers, each with its own pass criteria and signed sign-off: (1) opening balance — Fusion GL TB at go-live = NAV TB at cutover, to the cent in LCY and ACY; (2) in-flight transactions — every open Sales Order, Purchase Order, production order, unposted journal survives cutover with state and dimension context preserved; (3) document chain — sample n=50 Fusion AR/AP balances drilled back to originating NAV Sales/Purchase Invoice end-to-end; (4) statutory submission — VAT returns, SAF-T submissions, Intrastat, GoBD GDPdU exports filed in the cutover period reconcile across NAV and Fusion outputs; (5) parallel-run cumulative — 30–60 days of nightly delta reconciliation aggregated; (6) cutover sign-off — full evidence pack signed by tax, audit, finance, operations and IT leads.
Yes. NAV's per-company database segmentation makes multi-company reconciliation a first-class consideration. The microsoft dynamics nav migration reconciliation framework runs every layer per company in scope, then runs a consolidated reconciliation across companies (Fusion consolidated TB vs sum of NAV per-company TBs, intercompany G/L Entry pairs reconciled and eliminated). Whether the target Fusion shape is one ledger with multiple BUs or multiple ledgers consolidating via FCCS, the reconciliation framework emits the right shape — with per-company evidence pages plus a consolidated evidence page, all bound into the same pack.
Statutory reconciliation is its own layer in the framework. The German GoBD GDPdU export for the cutover period must produce identical output whether generated from NAV or from the long-term NAV archive populated by the migration — same posting chain, same hash signatures, same read-access audit. UK MTD VAT submissions for the cutover quarter must reconcile across NAV-generated returns and Fusion-generated returns. SAF-T submissions (Norway, Poland, Portugal, France, Lithuania, Romania) for the cutover period must reconcile across both systems. The microsoft dynamics nav migration reconciliation framework runs the cutover-period statutory output through both pipelines and surfaces any variance for resolution before sign-off.
Yes. Document chain reconciliation samples Fusion AR and AP balances at a defined point in time and drills back through the migration evidence: Fusion GL line → originating Fusion AR/AP transaction → migration crosswalk → original NAV Customer Ledger Entry or Vendor Ledger Entry → NAV Sales Header 36 / Sales Line 37 or Purchase Header 38 / Purchase Line 39 → supporting attachments. Every hop is signed and timestamped. Auditors get a sample of 30–50 drill-backs in the evidence pack plus on-demand drill-back access into the long-term NAV archive for any specific balance they want to investigate. The chain is intact.
Parallel-run reconciliation is layer five of the framework. After initial cutover, NAV continues taking transactions for 1–2 month-end cycles while Fusion runs the same business in parallel. Every night, NAV deltas are captured through SQL Server change tracking or the Modified DateTime watermark, replayed to Fusion via FBDI or REST, and reconciled by morning. The cumulative parallel-run reconciliation pack is assembled across the window: 30–60 days of nightly G/L Entry parity, subledger parity, inventory parity and open-document parity, plus 1–2 month-end TB/AR aging/AP aging/inventory valuation reconciliations. Sign-off on the parallel-run pack is the gate to NAV moving to read-only archive mode.
A single signed evidence pack: opening-balance reconciliation page, in-flight transaction reconciliation page, document-chain drill-back evidence (n=50), statutory-submission reconciliation page (VAT, SAF-T, Intrastat, GoBD), parallel-run cumulative reconciliation page covering the full window, plus per-company and consolidated evidence pages for multi-company estates. The pack carries PDF signatures from tax, audit, finance, operations and IT leads. The steering committee signs the cover page. The signed pack is archived for the audit retention window (SOX 7yr, IRS 4-7yr, HMRC 6yr, GoBD 10yr, SAF-T per-jurisdiction) and is the definitive answer to any future question about whether the microsoft dynamics nav migration reconciliation was complete and correct.
