Overview
Moving from Spectrum ERP to Epicor ERP is a full-sub-ledger migration that must reconstruct financial integrity across all modules. Spectrum organizes cost tracking around Jobs and Work Orders with phases and cost codes nesting under the Job; Epicor uses a different project structure with Project, Phase, and Task hierarchy that requires careful segment mapping. We sequence the migration in dependency order—GL accounts first, then chart-of-accounts segments, then Jobs and Work Orders, then sub-ledgers—ensuring that sub-ledger balances (A/R, A/P, Payroll, Inventory) reconcile to the GL after every phase. Epicor's Kinetic platform operates on an AKS-containerized cloud architecture; on-premises Kinetic deployments are no longer receiving active development. We flag workflows, automations, and custom reports as rebuild-only scope and deliver a written inventory for the customer's implementation team post-migration.

Object mapping
Each row shows how a Spectrum ERP object lands in Epicor Prophet 21, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Spectrum ERP
Job / Project
Epicor Prophet 21
Project (PM Module)
1:1Spectrum Jobs map to Epicor Project records with the phase and cost-code hierarchy preserved as Epicor Phase and Task records. The Spectrum Job number becomes the Epicor Project Number; Job phase descriptions map to Phase descriptions. Cost codes from Spectrum become either Task-level cost categories or UD fields on Phase depending on the destination configuration. Historical job cost summaries migrate as Phase Actuals against the project. We validate the project start and end dates from Spectrum's Job Master and flag any overlapping or duplicate job numbers for reconciliation before import.
Spectrum ERP
Work Order
Epicor Prophet 21
Job (MES Work Order)
1:1Spectrum Work Orders attached to Jobs map to Epicor MES Work Orders. The Job-to-Work Order linkage in Spectrum becomes the parent Job reference in Epicor. Labor, materials, and equipment allocations from the Spectrum work order migrate to Epicor JobMtl, JobOper, and JobEquip records. Any notes or attachments on the Spectrum work order transfer as JobHead checkboxes or Document Reference records in Epicor. We validate the work order-to-job relationship integrity before inserting child records.
Spectrum ERP
G/L Account
Epicor Prophet 21
G/L Account (GL Module)
1:1Spectrum G/L Accounts migrate to Epicor GL Account with segment mapping resolved during the pre-migration mapping session. Spectrum's account structure (segment count, segment meanings, rollup hierarchies) maps to Epicor's account segments and account groups. The Add G/L Journal Entries web service in Spectrum surfaces both debit and credit lines per entry; we use these to reconstruct the full journal entry in Epicor's G/L Journal Entry form. Account numbers and descriptions migrate directly; the account type and posting definitions map to Epicor GL Account categories.
Spectrum ERP
G/L Journal Entry
Epicor Prophet 21
G/L Journal Entry
1:1Both sides of every journal entry migrate together to preserve trial balance integrity. Epicor requires that debits and credits balance within a journal entry batch. We extract journal entry data from the Spectrum Add G/L Journal Entries web service which returns both debit and credit lines per entry, and insert the balanced batch into Epicor GL Journal Entry with the same entry date, description, and source module reference. Historical entries are posted as Adjusting entries with a migration-source reference flag for audit. Trial balance reconstruction is validated after this phase before sub-ledger migration begins.
Spectrum ERP
Chart of Accounts
Epicor Prophet 21
GL Account + Account Segments
lossySpectrum's Chart of Accounts with Excel template bulk import maps to Epicor's GL Account Master with segment definitions. The number of segments (typically 1-6 in Spectrum) maps to Epicor GL Account segments, and the rollup hierarchies map to Epicor Account Groups. We conduct a pre-migration mapping session to confirm segment count and meaning, then bulk-load the account structure before any transaction data moves.
Spectrum ERP
Employee / HR Records
Epicor Prophet 21
Employee (HR Module)
1:1Spectrum Employee records migrate to Epicor Employee with personal data, dependents, and insurance records. Certified payroll and union rule compliance fields require remapping because Spectrum stores these in configuration-specific fields that vary by customer. We extract the union rule set, deduction codes, and pay group assignments during scoping, then map them to Epicor's Pay Group, Deduction, and Tax Configuration during migration. Any training certifications migrate as Employee Training records in Epicor HR.
Spectrum ERP
Payroll / Certified Payroll
Epicor Prophet 21
Payroll (Payroll Module)
1:1Spectrum payroll is one of its strongest modules, supporting multi-union rules and certified payroll. Pay stubs, pay groups, and deduction codes carry over but deduction code remapping is required because Epicor's deduction model uses different code structures. We identify all active deduction codes, benefit codes, and garnishment codes in Spectrum and map them to Epicor equivalents during the mapping session. Historical pay stub records migrate as Payroll History with full earning and deduction detail. Union rule sets are preserved in Epicor Pay Groups as pre-configured rules.
Spectrum ERP
Equipment
Epicor Prophet 21
Equipment (Maintenance Module)
1:1Spectrum Equipment Tracking records migrate to Epicor Equipment Master with the same equipment ID, description, serial number, and classification. Preventive maintenance schedules and work orders attached to equipment migrate as Epicor JobMtl/JobOper with the maintenance type flagged. Equipment Work Order components and notes carry over as Job records with the maintenance-type flag set. Any equipment images from Spectrum's Document Imaging service transfer as Equipment attachments in Epicor.
Spectrum ERP
Equipment Work Order
Epicor Prophet 21
Maintenance Work Order (FS Module)
1:1Spectrum Equipment Work Order records migrate to Epicor Field Service Work Orders or Plant Maintenance Work Orders depending on the destination configuration. The work order-to-equipment linkage is preserved as the EquipID reference. Labor hours, parts, and notes migrate to the corresponding work order detail records. If the customer uses Epicor's Field Service module, the work order migrates as an FS-Project-linked Work Order.
Spectrum ERP
Accounts Receivable
Epicor Prophet 21
AR Invoice / Customer
1:1Spectrum A/R customer records and open invoice data migrate to Epicor Customer and AR Invoice records. Customer addresses, payment terms, and credit limits transfer directly. Open invoices (unpaid at migration date) migrate as Open AR invoices with the original invoice date and aging preserved. Historical paid invoices migrate as AR Invoice history records. The Spectrum invoice number becomes the Epicor InvoiceNum with a source-reference field for audit traceability.
Spectrum ERP
Accounts Payable
Epicor Prophet 21
AP Invoice / Vendor
1:1Spectrum A/P vendor records and open invoice data migrate to Epicor Vendor and AP Invoice records. Vendor addresses, payment terms, and 1099 settings transfer directly. Open invoices (unpaid at migration date) migrate as Open AP invoices with the original invoice date and aging preserved. Historical paid invoices migrate as AP Invoice history records. The Spectrum invoice number becomes the Epicor InvoiceNum with a source-reference field for audit traceability.
Spectrum ERP
Inventory
Epicor Prophet 21
Part / Warehse
1:1Spectrum Inventory records migrate to Epicor Part records with the same part number, description, uom, and on-hand quantities by warehouse. Bin locations from Spectrum map to Epicor WarehseBin records. Part classes and commodity codes map to Epicor Product Group or UD fields. If Spectrum maintains lot or serial number tracking, those records migrate as PartLot entries with expiry dates and quantity balances.
Spectrum ERP
Custom Fields (Service Hub)
Epicor Prophet 21
UD Fields on Business Objects
1:1Spectrum Service Request custom fields (up to 4 per form) migrate to Epicor UD (User-Defined) fields on the relevant business object. We extract the field definitions (label, data type, required flag) and current values during scoping, then create Epicor UD columns via the Kinetic Data Model before migration. If the destination allows fewer than 4 UD fields on a specific object, we flag the constraint during scoping for the customer to resolve before migration.
Spectrum ERP
Document Imaging / Images
Epicor Prophet 21
Document Attachments (EDMS)
1:1Project Log Images, Work Order Images, and Employee Images from Spectrum's Document Imaging web services migrate as Epicor Document Management attachments linked to the corresponding business object (Project, Job, Employee). Binary image data requires a separate transfer pass after relational records are inserted because image files must be uploaded after the parent record ID is known. We sequence document migration as the final pass after all primary records are committed.

Migration approach
Discovery and scoping
We audit the source Spectrum ERP tenant across all active modules: Job Master, Work Order, G/L Account, A/R, A/P, Payroll, Inventory, Equipment, and Document Imaging. We confirm the PRO-IV framework version and SQL Server version with the customer, and verify whether Trimble has scheduled a framework upgrade. We identify all active deduction codes, union rule sets, cost-code structures, and Service Hub custom field configurations. The discovery output is a written migration scope document listing every object, record count estimate, and any source constraints (rate limits by plan, access revocation timeline).
Chart of accounts and GL segment design
We conduct a mapping session with the customer's accounting team to define the Epicor GL segment structure. Spectrum's account segments and rollup hierarchies map to Epicor's GL Account Master with segments and account groups. We confirm the number of segments (typically 1-6), segment meanings, and the account type posting definitions before deploying the account structure into the Epicor sandbox. This step must complete before any transaction data moves because all transaction records reference GL accounts.
Sandbox migration and reconciliation
We run a full migration into an Epicor sandbox environment (Full Copy or Partial Copy) using production-like data volume. The customer's accounting team and IT lead reconcile record counts against Spectrum source reports: Jobs in, Work Orders in, GL entries in (balanced), A/R invoices in, A/P invoices in, Employees in, Payroll history in, Equipment in, Inventory in. We spot-check 25-50 random records across modules against the Spectrum source. Any mapping corrections, missing lookup values, or data quality issues surface here before production migration begins.
Journal entry completeness validation
We extract every journal entry from Spectrum via the Add G/L Journal Entries web service and validate that each entry balances (debits equal credits) before building the Epicor import batch. Entries that do not balance are flagged for the customer's accounting team. We load the balanced batches into Epicor GL Journal Entry with a migration-source reference for audit. The trial balance is validated after journal entry load before sub-ledger migration begins, ensuring that Epicor's GL is the authoritative record for reconciliation.
Sub-ledger migration in dependency order
We run production migration in record-dependency order: GL Accounts and Chart of Accounts (segments deployed), Journal Entries (balanced batches), Customers and Vendors (referenced by invoices), A/R and A/P Invoices (with customer/vendor lookups resolved), Employees (referenced by payroll), Payroll History (with employee and deduction lookups resolved), Jobs (project hierarchy), Work Orders (with Job parent references resolved), Equipment and Maintenance Work Orders, Inventory Parts and Warehouses, and Document/Image attachments (final pass after all parent records are committed). Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, final reconciliation, and handoff
We freeze Spectrum writes during cutover, run a final delta migration of any records modified during the migration window, then mark Epicor as the system of record. We deliver a written inventory of all workflows, automations, certified payroll rule sets, and custom reports requiring rebuild in Epicor. We do not rebuild these as part of standard migration scope. We support a one-week hypercare window where we resolve any reconciliation issues raised by the customer's team. Epicor Pro Services engagement or a certified Epicor partner rebuilds workflows, automations, and custom reports post-migration as a separate workstream.
