Rehearsed playbook for in-flight transactions, consumption-pricing renewal timing, REST/OData endpoint switch, Branch-by-Branch or all-at-once sequencing, and pre-staged rollback. Smoke-tested integrations, signed reconciliation, no-surprises go-live.
Cutover failure has outsized consequences: revenue impact, customer impact, audit exposure. The playbook is rehearsed twice, pre-staged with rollback, and signed off domain-by-domain.
All the prior work — assessment, mapping, dress rehearsals, parallel run — funnels into the acumatica migration cutover window. This is the 36-72 hour period during which Acumatica stops being the system of record and Fusion becomes it. By the time cutover starts, mapping is signed, reconciliation is proven to the cent across multiple dress rehearsals, integrations have been smoke-tested in test pods, and the freeze plan is signed by every domain owner. Even so, the cutover itself is high-stakes: a defect that surfaces in cutover smoke tests has to be resolved within the freeze window or the go-live slips by 1-2 weeks.
Syntra ETL's acumatica migration cutover playbook is built for this reality. The 54-72 hour freeze window has explicit hour-by-hour activities, named owners, sign-off gates and rollback decision points. In-flight transaction handling is decided weeks earlier and rehearsed in dress rehearsal. REST/OData endpoint switch-over is staged with smoke-test scripts for every integration. The consumption-pricing renewal date is built into timing so the Acumatica subscription terminates cleanly.
Branch-by-Branch wave cutover (for tenants with 10+ Branches) and all-at-once cutover (for tenants with 1–5 Branches) are both supported. The choice is made in the assessment phase based on risk appetite, integration complexity and Inter-Branch Transaction volume. Either pattern uses the same playbook structure with the same rollback contingency.
Each pillar is pre-built in the playbook and tuned to your specific Acumatica configuration.
Hour-by-hour activities: freeze starts, delta extract, FBDI loads, reconciliation, sign-off, integration switch, smoke tests, go/no-go decision. Each step has named owner and entry/exit criteria.
Open SOOrders, POOrders, AP Bills, AR Invoices, Production Orders, Project tasks classified close-before / migrate-in-flight / re-enter-post. Decision matrix signed in advance.
10-30 downstream integrations switched from Acumatica to Fusion endpoints (direct or via OIC). Smoke-test scripts for each. Pre-staged rollback to old endpoints.
Cutover scheduled to land before next Acumatica renewal date. Parallel-run consumption budgeted. Post-cutover read-only mode minimizes ongoing consumption charges.
For tenants with 10+ Branches, optional wave cutover: pilot Branch first, learn, then remaining Branches in successive waves over 4-12 weeks.
Final Acumatica backup pre-cutover. Subscription preserved 30 days. Integration old endpoints kept warm. If cutover smoke tests fail beyond fix window, go-no-go reverts to no-go.
A typical 54-hour Friday-evening through Sunday-evening cutover window.
Acumatica users notified, transaction entry frozen. Last-call window for completing in-progress entries. Acumatica integrations placed in pause mode (queuing but not processing). Final Acumatica backup captured. Sign-off: IT Lead.
Final delta extract from Acumatica via OData modified-since filters across every entity. Hash-signed manifests captured. Stage to Parquet on object storage. Sign-off: Data Engineering Lead.
Final FBDI payloads submitted to Fusion ESS in dependency order: master data first, open transactions next, historical balances, then any final transaction history catch-up. Monitored to completion. Sign-off: Fusion Functional Lead.
Full reconciliation pack generated: GL parity, AP aging, AR aging, inventory on-hand, FA register, project actuals, ASC 606 rollforward, multi-state sales tax. Variances reviewed by domain owners. Sign-off: Controller + Audit Lead.
REST/OData endpoint cutover for downstream integrations. Each integration smoke-tested (payment, shipping, eCommerce, CRM, EDI, payroll, sales-tax). Failures revert to Acumatica endpoints. Sign-off: Integration Lead.
Go/no-go decision based on reconciliation sign-off, integration smoke tests and persona acceptance tests. If go: production cuts to Fusion, Acumatica moves to read-only. If no-go: rollback path executes. Sign-off: Executive Sponsor.
Acumatica migration cutover doesn't end at go-live. Stabilization closes only after the first clean month-end close.
1-hour daily call with finance, AP, AR, operations, project controllership. Defect log triaged. Hot-fix mapping refinements deployed via converter re-runs. Cadence reduces from daily to weekly as defects subside.
Mapping refinements deployed daily into Fusion deltas. Each fix logged in the variance disposition trail. Defect SLA: P1 within 4 hours, P2 within 24 hours, P3 within 1 week.
Reconciliation pack regenerated daily for the first 2 weeks, comparing Fusion balances to the previous-day Fusion baseline and to the pre-cutover Acumatica baseline. Domain owners review.
Stabilization gates on the first clean month-end close in Fusion with reconciliation matching pre-cutover parallel-run numbers to the cent. Once achieved, stabilization closes.
Acumatica tenant moves to read-only archive mode. Audit, tax and operational teams retain read access via Acumatica's standard UI for the duration of the wind-down period.
Acumatica subscription cancelled at the next renewal date (typically 4-8 weeks post-cutover) with formal termination letter and final consumption settlement. Annual subscription savings begin.
Acumatica migration cutover is the orchestrated, time-boxed transition during which Acumatica stops being the system of record and Oracle Fusion becomes it. It is not a single moment — it is a 36-72 hour window with explicit pre-cutover preparation, freeze/extract/load/reconcile/sign-off sequence, and post-cutover stabilization. The acumatica migration cutover playbook covers in-flight transaction handling, consumption-pricing renewal timing, REST/OData endpoint switch-over for downstream integrations, Branch-by-Branch sequencing where applicable, and rollback contingency. Cutover failure has outsized consequences (revenue impact, customer impact, audit exposure), so the playbook is rehearsed twice before execution.
Acumatica's consumption-based pricing (transactions per month, not per user) means the tenant accrues cost based on usage volume during the contract period. This affects acumatica migration cutover timing in two ways. First, the cutover should land before the next renewal date so the Acumatica subscription can be cancelled without auto-renewal — typically the cutover is scheduled 4–8 weeks before renewal to allow a parallel-run buffer and clean termination. Second, during parallel run, Acumatica usage continues so consumption costs continue — but post-cutover the tenant moves to read-only mode (typically minimal-usage), letting consumption fall to a floor. The playbook timing is reviewed with the Acumatica account team to confirm the exact terms apply to your contract.
In-flight transactions — open sales orders not yet shipped, open purchase orders not yet received, pending AP Bills not yet approved, AR Invoices in dunning, production orders in progress, project tasks in progress — are the highest-risk class of cutover data. The playbook treats them in three categories. (1) Close-before-cutover: small, near-completion transactions get closed in Acumatica before the freeze. (2) Migrate-in-flight: medium-volume transactions migrate with their full state (status, approval level, partial allocations) via FBDI imports designed for in-flight migration. (3) Re-enter-post-cutover: large or complex transactions get printed, frozen, and re-entered in Fusion post-cutover. The split is decided per customer based on volume and complexity, signed off before the cutover.
Acumatica typically has 10-30 active downstream integrations consuming Contract-Based REST API and OData v4 endpoints: payment processors, shipping providers, eCommerce platforms, EDI partners, CRM sync, analytics tools, banking feeds. The acumatica migration cutover playbook coordinates the REST/OData endpoint cutover: integrations get pointed at Acumatica read-only endpoints during parallel run (for legacy reference), and at Fusion REST endpoints (via OIC where transformation is needed) for new transactions. The switch happens in a coordinated window — typically Saturday morning — with smoke tests for every integration before declaring cutover complete. Roll-back paths are pre-staged in case any integration fails.
Both patterns are viable in acumatica migration cutover. All-at-once cutover is simpler (single freeze window, single reconciliation, single integration switch) and works for tenants with 1–5 Branches that share a single operating model. Branch-by-Branch cutover (sometimes called wave cutover) lets a customer migrate one Branch first as a pilot, learn from the experience, and then migrate remaining Branches in successive waves. This works well for customers with 10+ Branches across legal entities or geographies, particularly where Inter-Branch Transactions are limited. The playbook supports both patterns — the choice is made in the assessment phase based on customer risk appetite, integration complexity and Branch-level Inter-Branch Transaction volume.
The freeze window is the period during which Acumatica stops accepting new transactions. For all-at-once cutover, the freeze typically runs Friday 5pm through Sunday 11pm (54 hours). Saturday morning: final delta extract from Acumatica via OData modified-since filters; FBDI loads to Fusion. Saturday afternoon: reconciliation runs across all six validation domains. Saturday evening: variance review, sign-off by domain owners. Sunday morning: integration endpoint switch, smoke tests. Sunday afternoon: user acceptance smoke tests with key personas (AP clerk, AR clerk, project manager, warehouse manager). Sunday evening: cutover go/no-go decision; production cut to Fusion.
The acumatica migration cutover playbook includes explicit rollback contingency. Before the freeze starts, a final Acumatica backup is captured. Acumatica subscription is NOT cancelled until 30 days post-cutover. Downstream integrations have their pre-cutover endpoint configurations preserved. If a critical defect surfaces during cutover smoke tests that can't be resolved within the freeze window, the cutover declares no-go: Acumatica is restored to active mode (no data loss because nothing was archived yet), integrations point back to Acumatica, and the issue is diagnosed in the following days for a re-scheduled cutover. Rollback has never been needed on a Syntra ETL Acumatica cutover, but the contingency is always pre-staged.
Post-cutover, the first 2-4 weeks are stabilization. Acumatica migration cutover doesn't end at the go-live moment. Daily check-ins with finance, AP, AR, operations, project controllership. Defect log captured and triaged hourly. Hot-fix mapping refinements deployed via converter re-runs into Fusion deltas. Daily reconciliation pack delivered to domain owners. After the first month-end close completes cleanly in Fusion with reconciliation matching the parallel-run Acumatica numbers to the cent, stabilization closes. Acumatica tenant moves to read-only archive mode. Acumatica subscription gets cancelled at the next renewal date.
