Overview
Migrating from Infor M3 to Infor CloudSuite is an intra-vendor move that still requires a structured data migration because M3 and CloudSuite are separate tenants with different API endpoints, schema structures, and configuration models. M3's on-premises or legacy cloud architecture requires exports via Infor OS BaaS with its 25-second handler timeout and per-tenant concurrency caps, while CloudSuite ingestion uses Infor's Data Loader or direct API with import rules for field-length and value-type differences. We sequence the migration by dependency chain — Items before BOMs, BOMs before Work Orders, Accounts before Transactions — and flag multi-company and multi-site configurations as requiring explicit tenant mapping in CloudSuite. Custom fields behave inconsistently across M3 modules; we scan per-company and preserve a manifest so the customer can re-create any omitted fields post-migration. Workflows, automations, and output management forms do not migrate as code; we deliver a written inventory of every active workflow and configured form for the customer's admin to rebuild in CloudSuite's Ming.le or Infor OS workflow designer.

Object mapping
Each row shows how a Infor M3 object lands in Infor CloudSuite Corporate, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Infor M3
Item (MITMAS)
Infor CloudSuite Corporate
Item / Product
1:1M3 Item master records map to CloudSuite Item. M3's costing model associations (MITCOU) and unit-of-measure conversions (MITCUM) require pre-load before Item import so that cost element references are satisfied. Attribute-controlled items and configured products are flagged during scoping because they require their attribute schemas pre-created in CloudSuite before the Item load. Standard price, cost, and lead times transfer directly; custom pricing tiers require separate Price List configuration in CloudSuite.
Infor M3
Customer Order (OIS100/OIS101)
Infor CloudSuite Corporate
Customer Order
1:1M3 Customer Order header (OOHEAD) and lines (OOLINE) map to CloudSuite Customer Order. User-defined fields on OOHEAD and OOLINE are accessible through the API only if defined in the supported UDF table list; we scan the CMS082 configuration per company before export and preserve a manifest of any omitted UDF values for manual re-entry. Order statuses map to CloudSuite lifecycle states with a transition matrix we agree on during scoping.
Infor M3
Supplier Order / Purchase Order (PPS200/PPS201)
Infor CloudSuite Corporate
Purchase Order
1:1M3 Purchase Order header (MPHEAD) and lines (MPLINE) map to CloudSuite Purchase Order. Supplier invoice records (MPIINV) map separately and require the Supplier record resolved first. Multi-line supplier invoices with mixed currency or tax treatments require value mapping before CloudSuite import because CloudSuite handles tax at the line level by default.
Infor M3
Bill of Material (BOM) (CMSMOG/MITBAL)
Infor CloudSuite Corporate
Bill of Material
lossyM3 BOMs have multi-level structures with operations, resources, and by-products. We flatten and re-hierarchy BOMs at the destination, extracting the full BOM tree via MITBAL before writing to CloudSuite. Configured and attribute-controlled products require their component attribute definitions pre-created in CloudSuite's product configurator; we flag any BOMs that reference undefined attributes and escalate before migration begins.
Infor M3
Work Order (SFCOPO/SFCMPO)
Infor CloudSuite Corporate
Work Order
1:1M3 Work Orders depend on BOM and routing definitions loaded first. We export Work Order header, operations, and time entries (SFCOPT/SFCMOP) and map operation statuses to CloudSuite Work Order lifecycle states. Work Orders with open time entries or incomplete operations are flagged for customer decision on whether to carry them forward as open or close them in M3 before migration.
Infor M3
Inventory (WHINAH)
Infor CloudSuite Corporate
Inventory / Stock
1:1M3 inventory quantities, locations, and bin structures map to CloudSuite Warehouse and Stock records. Warehouse and bin location mapping requires explicit configuration because M3's location structure (warehouse-bin-location) does not map directly to CloudSuite's nested location model. We extract the full location hierarchy and create a mapping table during scoping.
Infor M3
Distribution Order (MWSELS/MWSHPO)
Infor CloudSuite Corporate
Distribution Order
1:1M3 inter-site and inter-company transfer orders map to CloudSuite Distribution Order. Shipment and receipt details transfer with status mapping from M3's transfer lifecycle to CloudSuite's receiving workflow. Distribution Orders require both source and destination warehouse locations pre-loaded and mapped.
Infor M3
Financial Ledgers (FGLEDG/FBSLED)
Infor CloudSuite Corporate
General Ledger
1:1M3 general ledger records map to CloudSuite Financials with explicit chart of accounts mapping. Accounts Payable and Accounts Receivable open items require careful sequencing after account structures are confirmed. We export open AP and AR records with aging buckets and map to CloudSuite's payment terms and dunning configuration. Closed periods are archived; open periods carry forward with a post-migration reconciliation step.
Infor M3
Chart of Accounts (GBCOY/FINBOA)
Infor CloudSuite Corporate
Chart of Accounts
1:1M3 multi-company chart of accounts maps to CloudSuite Financials account hierarchy with company associations. Account segments from M3's company-level COA structure require mapping to CloudSuite's dimensional chart. Intercompany accounts require explicit tenant mapping when migrating multi-company configurations to CloudSuite.
Infor M3
Fixed Assets (FASMAS)
Infor CloudSuite Corporate
Fixed Assets
1:1M3 fixed asset master records include depreciation schedules and asset classifications. We export asset masters and depreciation history, flagging any assets with open depreciation periods for customer confirmation before migration. Assets in M3's partially depreciated state must map to CloudSuite's depreciation method configuration.
Infor M3
Departments and Cost Centers (HRDEPT/FINGRP)
Infor CloudSuite Corporate
Organizational Units
1:1M3 organizational units used across finance, HR, and operations modules map to CloudSuite cost center and department structures. We extract the full hierarchy and create lookup tables for use in financial ledger mapping and reporting structure recreation.
Infor M3
Custom Fields (CDF and UDF)
Infor CloudSuite Corporate
Custom Properties
lossyM3 custom fields exist in two forms: Customer-Defined Fields (CDF) accessible via Infor Enterprise Search and API, and hardcoded User-Defined Fields (UDF) on specific tables (MITVEN, MPHEAD, MPLINE, OOHEAD, OOLINE). We scan custom field definitions per company and per module, filter out inaccessible UDF values, and preserve a manifest of omitted fields with their table, column, and last-known values for manual re-creation in CloudSuite. The manifest is delivered alongside the migration output.

Minimum 20-user licensing requirement inflates migration scope
Infor CloudSuite Corporate gotchas
Infor OS tier-based usage limits gate API and BaaS capabilities
Custom Fields use inconsistent naming across Infor editions
SQL migration utility requires source database access
Multi-site and multi-currency data require separate period closure sequencing
REST API payload and timeout limits restrict bulk migration throughput
Pair-specific challenges
Migration approach
Discovery and dependency mapping
We audit the source M3 tenant across all modules, identifying object volumes (Items, Orders, BOM levels, Work Order counts, inventory locations, ledger account count), multi-company configuration (number of companies, intercompany transaction volume), custom field definitions per company and module, and any active RPG-based custom services that may not be API-accessible. We map the full dependency chain for each object type and produce a written migration scope that identifies the largest extraction objects (for pagination strategy), BOM complexity, and multi-site scope. The discovery output is a migration inventory with record counts and a sequencing plan.
API constraint assessment and pagination design
We assess the source tenant type (PRD vs non-PROD) to determine concurrency limits, identify the largest objects that will trigger pagination against the 25-second handler timeout, and design the chunking strategy (page size, checkpoint resume logic). For objects exceeding 100,000 records, we design explicit pagination with cursor-based or offset-based paging and schedule these extractions during off-peak API windows. We also assess whether any data lives exclusively in M3 panel exports rather than API-accessible records, which requires a different extraction approach.
Schema preparation in CloudSuite
We configure the CloudSuite destination environment before any data ingestion. This includes setting up the multi-company structure (if migrating from an M3 multi-company configuration), configuring the chart of accounts mapping, pre-creating attribute schemas for configured and attribute-controlled products, defining custom properties for any customer-specific fields being migrated, and setting up warehouse and location hierarchies. Import rules are defined in CloudSuite's Import Rule Definition form to handle field-length constraints and value-type conversions (Y/N to 1/0, date formats, decimal handling). A preliminary data transfer to a non-production CloudSuite environment validates the import rules and surfaces mapping errors before production migration.
Sandbox migration and reconciliation
We run a full migration into a CloudSuite sandbox or staging environment using production-like data volumes. The customer's functional leads (finance, operations, IT) reconcile record counts, spot-check 25–50 records per object against M3 source data, and validate financial balances and inventory quantities. Any mapping corrections, import rule updates, or schema changes happen in the sandbox, not in production. The customer signs off on the sandbox migration before production migration begins. BOM structures are validated for configured products, and any missing attribute definitions are flagged and resolved at this stage.
Production migration in dependency order
We execute production migration in dependency order: organizational units and cost centers first (for financial and reporting structure), then Items with costing models, then BOMs and routing definitions, then Inventory, then Customer Orders and Supplier Orders (with Work Orders deferred until BOMs are confirmed), then Distribution Orders, then Financial Ledgers and fixed assets, then custom fields last. Each phase emits a row-count reconciliation report and a data quality summary (null rates, truncation flags, mapping exceptions) before the next phase begins. Large object extractions run with explicit pagination and checkpoint resume logic. Multi-company configurations migrate one company at a time with intercompany transaction mapping deferred until all companies are loaded.
Cutover, validation, and workflow handoff
We freeze writes to M3 during cutover, run a final delta migration of any records modified during the migration window, validate financial balances between M3 and CloudSuite (trial balance reconciliation, open order count, inventory quantity totals), and enable CloudSuite as the system of record. We deliver a written inventory of every active M3 workflow, automation, and configured output form for the customer's admin to rebuild in CloudSuite's Ming.le workflow designer or Infor OS automation tools. We support a one-week hypercare window for reconciliation issues. Post-migration, we do not provide ongoing admin support, training, or workflow rebuild as standard scope; these are separate engagements.
