An ERP migration is judged by one moment: the first month-end close on the new system. Everything in this guide is arranged around making that close uneventful, and around deciding early whether a full migration is needed at all.

Decide whether to migrate at all

Before mapping a single field, check whether the problem lives in the ledger. If the books, costing and consolidation work and the pain is in the order desk, purchasing and customer service, a migration solves the wrong problem at the highest price. Panorama Consulting's 2026 ERP report found that more than a quarter of organisations exceeded their implementation budgets, with additional technology needs as the leading cause⁠1.

The alternative is to keep Acumatica as the book of record and change the work around it. OpenLazarus describes this pattern on its industry pages: it reads from the ERP and writes back where it has to, so orders, stock and customers stay on one record, and its engineers connect the ERP and phone lines, usually within a few weeks for a company of about 260 people, by its own estimate⁠2. Its pages do not say whether a ready-made Acumatica connection exists, so that should be confirmed before any commitment.

Getting data out of Acumatica

Acumatica provides three documented routes⁠3:

  • The contract-based REST API retrieves, creates and updates records, and can filter, page through results in batches or pull a single record. Default endpoints can be extended with custom fields.
  • OData comes in two forms. Feeds built on generic inquiries expose queries designed inside the instance; feeds built on data access classes return related data and can track deleted records.
  • Export to Excel on generic inquiries suits reference data and reconciliation checks.

Two details matter in a cut-over. Filtering on the last-modified date lets the team re-extract only what changed since the previous run, which shortens the final weekend. And API user caps and per-minute request limits are visible in the instance, so a large extract should be planned around them⁠3.

Customers on a private-cloud subscription already choose where their software and data reside⁠4, which can simplify taking a full database copy for the archive. Customers on the standard SaaS subscription should ask their partner how a final copy is provided.

The new system's side

Each vendor runs its own method. Epicor's Ascend programme uses AI-powered tools for ERP migrations and, Epicor says, helps qualified businesses go live in as little as 90 days⁠5. NetSuite delivers through its SuiteSuccess methodology, starting from industry-specific configurations⁠6. Business Central is implemented only by Microsoft partners⁠7. Odoo sends companies under 50 employees to fixed Success Packs, mid-sized companies to partners and companies above 250 employees to Odoo directly⁠8.

Whichever method applies, the questions are the same: who owns the data mapping, who signs off each test load, and what happens if the first close does not balance.

A phase-by-phase plan

  1. Scope. List what moves and what is archived, using the table above. Agree the cut-over date with finance, not IT.
  2. Extract and map. Pull master data through the API or OData, map it to the new structure and keep the mapping in a shared document.
  3. Two trial loads. Load into a test environment, reconcile balances and open items to the cent, and repeat with fresher data.
  4. Conference-room pilot. Run a week of real orders, receipts and invoices through the new system with the people who will use it.
  5. Cut-over. Freeze Acumatica, take a final incremental extract filtered by last-modified date, load opening balances and open transactions.
  6. Parallel close. Close the first month in both systems if the licences allow it, and compare.
  7. Archive and retire. Keep a read-only archive or full export under the company's control, then end the Acumatica subscription.

What a finished migration looks like

The first close on the new system completes on the usual timetable. Every open order and invoice from the cut-over date can be found in one place. Historical questions are answered from an archive the company controls, not from a vendor it has left. And the team can name, for each record type, which system is the book of record.

For companies weighing whether this project is needed at all, the main comparison sets the full alternatives side by side, including the option of keeping Acumatica and adding a layer for the work around it.

Questions buyers ask

How do you export data from Acumatica?

Acumatica offers a contract-based REST API that retrieves records in batches or one at a time, OData feeds built on generic inquiries or directly on its data access classes, and an Export to Excel action on generic inquiries. Filtering on the last-modified date allows repeated, incremental extracts during a cut-over.

How long does it take to move from Acumatica to another ERP?

Vendors quote their own timelines. Epicor says qualified businesses can go live in as little as 90 days with its AI-assisted Ascend programme, a vendor claim. Plan for at least one month-end close run in both systems, and note that Panorama's 2026 report found more than a quarter of ERP projects over budget.

Should we move all our history out of Acumatica?

Usually not. Most companies move master data, open transactions and opening balances, and keep full history in a read-only archive or an export they control. Moving every historical transaction multiplies the mapping and testing work.
