Overview

What this migration involves

Infor LN targets enterprise discrete manufacturers with multi-company, multi-site deployments on SQL Server, DB2, or Oracle backends, using a deep manufacturing data model built around Bills of Material, production orders, and cost element hierarchies. Acumatica is a cloud-native ERP with a customization framework built on extension fields and Data Access Classes (DACs), supporting manufacturing editions with multi-branch architecture and per-branch financial reporting. The migration from Infor LN to Acumatica requires mapping LN's party-and-address model to Acumatica's separate Customer and Vendor entities, translating LN's cost center and GL account codes into Acumatica's segment-structured chart of accounts, and handling LN's multi-company consolidation logic through Acumatica's branch-to-company configuration. We extract Infor LN master data via LN Exchange module or ION API (OAuth1.0a), stage it in a migration database, and load it into Acumatica using Acumatica's import scenarios and REST API. Workflows, ION-based approval chains, custom reports, and third-party integrations do not migrate — those are rebuilt post-migration using Acumatica's own tools. We preserve original create and modify timestamps, owner assignments resolved by email match against Acumatica users, and Infor LN's extended data structure fields in Acumatica Usr-prefixed custom fields. A sample migration with field-level diff precedes the full run, and a 24–48 hour delta pickup window captures in-flight records at cutover.

Why teams make this switch

Two sides of the same decision

Leaving

Infor LN logo

Infor LN

What's pushing teams away

  • Licensing cost and minimum user requirements (20 users) make it economically impractical for smaller manufacturers or organizations with seasonal headcount.
  • Steep learning curve and specialized consultant dependency for day-to-day administration create ongoing operational overhead after go-live.
  • Vendor audit requests and contract enforcement practices cause friction and distrust, with some organizations reporting extended pressure campaigns for access and documentation.
  • Modern, lighter-weight ERPs like NetSuite or Acumatica offer faster time-to-value for manufacturers without the depth of discrete engineering complexity that LN addresses.
  • Support quality is perceived as inconsistent across implementation partners, leading to variable post-go-live experiences.

Choosing

Acumatica logo

Acumatica

What's pulling them in

  • Unlimited user licensing lets companies add staff without per-seat billing shocks, making Acumatica cost-predictable at scale.
  • Flexibility and scalability earn consistent praise — users value a platform that adapts to vertical workflows without forcing a redesign.
  • Real-time visibility across financials, inventory, and projects gives mid-market businesses a consolidated operational view previously available only in enterprise-tier ERPs.
  • Cloud-native architecture with automatic updates removes infrastructure management burden from in-house IT teams.
  • Modular licensing lets companies start with one or two suites (Financials, Distribution) and expand into Manufacturing or CRM incrementally.

Object mapping

How Infor LN objects map to Acumatica

Each row shows how a Infor LN object lands in Acumatica, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Infor LN

Business Partner (tccom0101s000)

maps to

Acumatica

Customer + Vendor

1:many
Fully supported

Infor LN stores all parties (customers, vendors, prospects) in a single Business Partner table with a Type field. FlitStack splits these into separate Acumatica Customer and Vendor records based on the LN BP Type. B2B addresses attached to the BP map to Acumatica Address defaults on each entity.

Infor LN

BP Address (tccom0201s000)

maps to

Acumatica

Address (on Customer / Vendor)

1:1
Fully supported

LN BP address lines map directly to Acumatica's Address record attached to Customer or Vendor. The primary address flag and country code are preserved. Multiple addresses per BP become multiple Acumatica address records keyed to the same entity. Each address can be designated as billing or shipping within Acumatica's address types.

Infor LN

BP Contact (tccom0202s000)

maps to

Acumatica

Contact (on Customer / Vendor)

1:1
Fully supported

LN BP contact names, titles, phone numbers, and email addresses migrate to Acumatica Contacts attached to Customer or Vendor. The primary contact flag is preserved. Contact methods (phone, fax, email) map to Acumatica's Contact Methods table. Additional fields such as role and department can be added as custom fields if needed.

Infor LN

Item (tcibd001)

maps to

Acumatica

Inventory Item

1:1
Fully supported

LN Item records with Stock type map to Acumatica Stock Items; Non-Stock items map to Non-Stock Items. The LN Item Class drives Acumatica's Item Class assignment. Unit of Measure definitions from LN's UOM table are translated to Acumatica's UOM setup before item import.

Infor LN

Warehouse (tcinv2101s000)

maps to

Acumatica

Warehouse

1:1
Fully supported

LN warehouses map 1:1 to Acumatica Warehouses. The warehouse code, name, and address details carry over. Each warehouse's default location-to-bin structure maps to Acumatica Location records within the Warehouse. If multiple sites share a warehouse in LN, split them into separate Acumatica warehouses to maintain site-level inventory tracking.

Infor LN

Purchase Order (tdpur4101s000)

maps to

Acumatica

Purchase Order

1:1
Fully supported

LN purchase order headers and lines migrate to Acumatica Purchase Orders. Vendor ID, PO number, status, date, and terms are mapped. Line-level detail (item, quantity, UOM, site, unit cost, extended cost) maps to Acumatica POLine with the appropriate inventory and land cost accounts applied.

Infor LN

Sales Order (tdsos4101s000)

maps to

Acumatica

Sales Order

1:1
Fully supported

LN sales orders migrate to Acumatica Sales Orders with header fields (order number, customer ID, date, terms, ship-to address) and line fields (inventory ID, quantity, UOM, warehouse, unit price, line total) preserved. Open orders are prioritized; closed orders migrate as historical records.

Infor LN

GL Account (tfgld2063s000)

maps to

Acumatica

Account (GL)

1:1
Fully supported

LN GL accounts use a segmented numeric code (company-6, cost center-4, subaccount-2-2 structure). Each LN account must be mapped to an Acumatica Account with matching segment structure or a consolidated code. Value-by-value mapping is required because Acumatica validates account existence before transactional import.

Infor LN

Cost Element (ticpr0102s000)

maps to

Acumatica

Account / Financial Dimension

1:1
Fully supported

Infor LN's cost element hierarchy (material, labor, overhead, outside processing) has no native Acumatica equivalent. Cost element codes are preserved as a custom field on the Account (CostElement__c) or as a financial dimension depending on the Acumatica configuration chosen during schema setup.

Infor LN

Work Center (tirou0101s000)

maps to

Acumatica

Work Center (Manufacturing)

1:1
Fully supported

LN work centers and their associated operation rates (labor rate, machine rate, overhead surcharges) map to Acumatica Work Centers. The work center code, description, and linked cost rate records carry over. Resource calendars and capacity definitions are preserved as part of the work center setup.

Infor LN

BOM / Recipe (cicpr0102s000)

maps to

Acumatica

Bill of Materials

1:1
Fully supported

LN Bills of Material (BOMs) with multi-level structures, phantom BOMs, and BOM steps map to Acumatica Manufacturing BOMs. Each BOM version, revision, effective date, and line (component item, quantity per, operation step) migrates with step numbers preserved for production order routing.

Infor LN

Production Order (moeco1101s000)

maps to

Acumatica

Production Order

1:1
Fully supported

Open and recently closed LN production orders migrate to Acumatica Production Orders with the linked BOM revision, quantity, scheduled dates, and material allocations preserved. Header status (released, completed, closed) maps to Acumatica Production Order status codes. History lines are migrated as completed production records.

Infor LN

Inventory Valuation (tfincl0101s000)

maps to

Acumatica

Inventory Summary

1:1
Fully supported

LN inventory valuation records (on-hand quantity, average unit cost, last cost) migrate to Acumatica Inventory Summary records per item and warehouse. The on-hand quantity maps directly; the average cost is stored as the Last Cost on the Inventory Item for valuation purposes.

Infor LN

Fixed Assets (tfacr1001s000)

maps to

Acumatica

Fixed Asset

1:1
Fully supported

LN fixed asset records with acquisition cost, placed-in-service date, depreciation method, useful life, and accumulated depreciation migrate to Acumatica Fixed Assets. Depreciation schedules are preserved as Acumatica Fixed Asset depreciation records with the last depreciation period matching the LN cutoff date.

Infor LN

LN Custom Table / Extended Data

maps to

Acumatica

Custom Field (Usr-prefixed)

1:1
Fully supported

Infor LN extended data structures linked to standard tables via table ID and column name are exported as named-value pairs. These are created as Acumatica Usr-prefixed extension fields on the matching DAC (Customer, Vendor, InventoryItem, POOrder, SOOrder). Each custom field requires an Acumatica Customization Project to be published before data import.

Infor LN

LN Financial Period

maps to

Acumatica

Fiscal Year / Period

1:1
Fully supported

LN financial period definitions (fiscal year, period start/end dates, period status) migrate as Acumatica Fiscal Years and Periods. Closed periods are flagged as locked in Acumatica to prevent post-migration postings to historical periods. We also map the period calendar to Acumatica's fiscal year setup, ensuring the year-end close process aligns with LN's existing configuration.

Infor LN

Currency Rates (tcmcs0104s000)

maps to

Acumatica

Exchange Rate

1:1
Fully supported

LN currency exchange rates with effective dates migrate to Acumatica Exchange Rates. The From Currency, To Currency, Effective Date, and Rate are mapped directly. Acumatica's multiple exchange rate sources (manual, ECB, etc.) are noted and the LN rate source is documented for post-migration rate management.

Infor LN

Subaccount / Profit Center (tfgld2063)

maps to

Acumatica

Subaccount / Dimension

1:1
Fully supported

LN subaccount segments used for profit center reporting are mapped to Acumatica Subaccounts or Financial Dimensions depending on the Acumatica configuration. Each LN subaccount code is mapped value-by-value to ensure segment-based financial reporting continuity after migration. This mapping supports drill-down reporting and helps maintain consistent cost allocation across the new system.

Pair-specific challenges

  • LN UOM conversions require pre-import Acumatica UOM definition

    Infor LN stores items with base UOMs and alternative UOMs with conversion factors (e.g., Each to Box to Pallet). Acumatica enforces UOM existence before inventory quantities can be imported. If the LN item uses an UOM not defined in Acumatica, the import of that line fails or the quantity converts incorrectly. FlitStack extracts the complete LN UOM table first, creates matching Acumatica UOM definitions during schema setup, and validates all item-to-UOM relationships before PO and inventory import runs.

  • LN GL account segmentation doesn't auto-map to Acumatica's chart of accounts

    Infor LN uses a segmented GL account code structure (6-4-2-2 characters by default: company-cost center-subaccount-sub-subaccount) that Acumatica cannot import as-is. Acumatica's chart of accounts uses a flat AccountCD field. Attempting to import the full LN account code string into AccountCD will cause posting errors when Acumatica validates account length or format. FlitStack builds a value-mapping table for every LN account code, maps each segment to an Acumatica Subaccount or financial dimension, and validates the resulting combined account code before transactional import.

  • LN multi-company structure demands Acumatica branch mapping before any data loads

    Infor LN's multi-company database uses a separate financial company for each legal entity, each with its own chart of accounts and period definitions. Acumatica uses a single tenant with Companies and Branches. The LN financial company must be mapped to an Acumatica Company before any transactional data can import, because Acumatica validates the Company ID on every GL posting. FlitStack inventories all LN financial companies during discovery, maps each to an Acumatica Company or Branch per the agreed configuration, and loads company setup data before any transactional tables are imported.

  • LN ION Workflow and document authorization approval chains have no Acumatica equivalent

    Infor LN's ION Workflow engine drives document authorization with conditional approval chains, amount thresholds, manager hierarchy routing, and escalation rules. These automation rules are stored in ION and do not export via LN's standard data interfaces. Acumatica handles approvals through Hold flags, Approval Maps (scope-based), and Generic Inquiries — not through rule-based workflow chains. The approval logic must be redesigned in Acumatica after migration. FlitStack exports the LN workflow definitions as reference documentation for the Acumatica implementation team.

  • LN document numbering sequence is not a native Acumatica field

    Infor LN auto-generates document numbers (PO numbers, SO numbers, invoice numbers) using internal sequence counters that customers can extend. Acumatica uses Numbering Sequences configured in the SM.SO.SalesOrder number sequence definition, which can match LN's sequence values only if manually configured before import. If LN's last PO number is PO-2024-0892, Acumatica's PO numbering sequence must be set to start at 0893 to avoid duplicate key errors on new records. FlitStack exports LN's current sequence values during discovery and sets matching Numbering Sequences in Acumatica before transactional import begins.

Migration approach

Six steps for a successful Infor LN to Acumatica data migration

  1. Discover LN data model and build Acumatica schema plan

    FlitStack connects to the Infor LN database via read-only access or exports via LN Exchange and ION API. We inventory all standard entities (BPs, items, POs, SOs, warehouses, GL accounts, cost elements, work centers, BOMs, production orders), custom extended data structures, number sequences, and LN financial company definitions. We deliver an Acumatica schema setup plan: required Companies or Branches, custom Usr fields to create in the Customization Project editor, UOM definitions to create, GL account mapping table, and Acumatica number sequence settings — all before any data is moved.

  2. Configure Acumatica tenant and load master data

    We configure the Acumatica tenant with the Companies, Branches, UOMs, tax agencies, payment terms, and number sequences identified in the schema plan. Master data (Customers, Vendors, Inventory Items, GL Accounts, Warehouses, Work Centers, BOMs) is loaded in dependency order — BPs before transactions, GL accounts before inventory, UOMs before items. Each import uses Acumatica's import scenarios or REST API with field-level validation. Custom fields are created in the Customization Project and published before their corresponding data rows are imported.

  3. Migrate transactional records with validation and rollback

    Open and recently closed purchase orders, sales orders, inventory valuation snapshots, fixed assets, and production orders are imported in sequence order. Each entity is validated against Acumatica's referential integrity (vendor exists, item exists, GL account exists, site is defined). We run a field-level diff comparing source LN values to destination Acumatica values for a sample of 100–500 records before committing the full run. An audit log captures every insert, update, and skip. One-click rollback reverts the Acumatica tenant to its pre-migration state if reconciliation reveals data integrity issues.

  4. Run delta-pickup and final reconciliation

    A delta-pickup window of 24–48 hours runs concurrently with live LN operations, capturing any purchase orders, sales orders, or inventory adjustments created or modified during the cutover. We compare delta record counts and key totals (open PO value, on-hand inventory value by item) between the pre-delta snapshot and the delta import. If totals match within agreed tolerances, the migration is declared ready for go-live. If variances exceed tolerances, affected entity types are re-imported before final sign-off.

  5. Go-live with scoped read access and post-migration support window

    At cutover, the Acumatica tenant becomes the live system. FlitStack maintains scoped read access to the LN database for a 30-day post-go-live window to answer data questions and provide reference lookups. We deliver a data reconciliation report comparing LN closing balances to Acumatica opening balances for GL, inventory, and AP. Reports, dashboards, and workflows are rebuilt by your Acumatica admin using our exported LN workflow definitions and report layouts as reference. Integration connections (EDI, third-party APIs) are tested against the live Acumatica tenant during the support window.

Most Infor LN to Acumatica migrations complete in 6–8 weeks of clock time for under 100,000 records with a single financial company. Multi-site or multi-company LN environments with 500,000+ records or extensive extended data structures extend to 3–6 months. The longest phases are the discovery and schema setup (2–4 weeks) and the data validation loop before full import commits. Following discovery, a field-level diff of a 100‑record sample validates mapping accuracy and confirms rollback readiness before the bulk load. The delta‑pickup window (24–48 hours) captures any in‑flight changes at cutover, ensuring Acumatica reflects the final LN state when you go live.
