Overview
Moving from VAIL-ERP to Epicor ERP is a cross-domain migration: VAIL-ERP is a Velosi-built healthcare and multi-industry ERP organizing data across patients, encounters, employees, suppliers, inventory, and financial transactions, while Epicor ERP is a manufacturing-focused platform with deep support for production scheduling, BOM management, shop-floor execution, and distribution. We handle the data extraction from VAIL-ERP through direct database access coordinated with Velosi since no public API exists, then map operational records (employees, suppliers, inventory items, chart of accounts, tax codes, open AP/AR transactions) to their Epicor equivalents. Patient records, clinical encounters, and healthcare-specific custom fields have no direct Epicor counterpart and require a documented decision before migration: archive to a separate system, keep in VAIL-ERP read-only, or rebuild in a clinical module outside Epicor. We do not migrate workflows, automations, or dashboards as code; we deliver a written inventory of these for the customer's admin to rebuild in Epicor Kinetic.

Object mapping
Each row shows how a VAIL-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.
VAIL-ERP
Employee
Epicor Prophet 21
Employee (HCM)
1:1VAIL-ERP employee records (job titles, department assignments, compensation history, effective-dated changes) map to Epicor HCM Employee records. We preserve department assignments by resolving VAIL-ERP department codes to Epicor cost-center entities. Any VAIL-ERP employee records without a matching Epicor user account are held in a reconciliation queue for the customer's admin to provision before import. Note that VAIL-ERP HR data includes healthcare-specific fields (licensure, certifications, shift assignments) that Epicor HCM represents differently and may require custom UD field creation.
VAIL-ERP
Department
Epicor Prophet 21
Cost Center
1:1VAIL-ERP department and cost-center records are mapped to Epicor ERP Cost Center entities first, before any dependent record import. All downstream foreign-key references in employee, supplier, and financial transaction records are resolved against the cost-center mapping to maintain referential integrity during migration.
VAIL-ERP
Supplier
Epicor Prophet 21
Supplier
1:1VAIL-ERP supplier records (contact details, agreed pricing, contract references, payment terms) map to Epicor ERP Supplier records. We preserve the supplier's primary contact, address, and tax ID where present. Supplier-specific pricing agreements require a manual review post-migration because Epicor represents supplier pricing in the Purchase Order and AP modules rather than as standalone pricing agreement records.
VAIL-ERP
Inventory Item
Epicor Prophet 21
Part
1:1VAIL-ERP inventory items (part numbers, descriptions, stock levels, reorder points, location assignments) map to Epicor ERP Part records. Stock levels transfer to PartBin quantities per warehouse location. Multi-site VAIL-ERP deployments require Epicor Site and Warehouse records to be provisioned before inventory import so that PartBin entries carry the correct location reference.
VAIL-ERP
Chart of Accounts
Epicor Prophet 21
GL Account
1:1VAIL-ERP chart of accounts (account codes, descriptions, account types, cost-center assignments) maps to Epicor ERP GL Account structure. We flag any inactive or archived VAIL-ERP accounts that should not carry forward. Account segment structure (if VAIL-ERP uses cost-center or department segments) maps to Epicor's COA segment configuration.
VAIL-ERP
Tax Code
Epicor Prophet 21
Tax Connection / Tax Master
1:1VAIL-ERP tax codes (rate, jurisdiction, applicability flags) map to Epicor ERP Tax Connection rules and Tax Master entries. We flag any tax codes used in open AP/AR transactions so that the customer's admin can verify jurisdiction mapping in Epicor before those records post.
VAIL-ERP
Financial Transaction (AP)
Epicor Prophet 21
AP Invoice / AP Payment
1:1VAIL-ERP AP ledger entries (vendor invoices, payment history, terms) map to Epicor AP Invoice and AP Payment records. We preserve open items with invoice number, vendor reference, amount, due date, and currency. Closed items transfer as AP Invoice records with a paid status. GL account distribution from VAIL-ERP maps to Epicor AP Invoice Detail lines.
VAIL-ERP
Financial Transaction (AR)
Epicor Prophet 21
AR Invoice / AR Payment
1:1VAIL-ERP AR ledger entries (customer invoices, payment history, terms) map to Epicor AR Invoice and AR Payment records. We preserve open items with invoice number, customer account, amount, due date, and currency. Closed items transfer as AR Invoice records with a paid status. Note that VAIL-ERP customer records (if present in the finance module) may require separate Customer record creation in Epicor if not already mapped from the supplier/contact module.
VAIL-ERP
Financial Transaction (Journal)
Epicor Prophet 21
GL Journal Entry
1:1VAIL-ERP journal entries (transaction date, account code, debit/credit amounts, description, source module) map to Epicor ERP GL Journal Entry records. We preserve the journal entry number, entry date, and posting date. Multi-line journal entries transfer with all debit and credit lines intact and COA segment values mapped to Epicor's segment structure.
VAIL-ERP
User Account
Epicor Prophet 21
User
1:1VAIL-ERP user accounts (login, role, module access) map to Epicor ERP User records. Role mappings require a manual review because VAIL-ERP role structures are module-specific and do not map directly to Epicor's Kinetic role and permission framework. We deliver a role reconciliation worksheet for the customer's admin to resolve before user access is configured.
VAIL-ERP
Document (Attachments)
Epicor Prophet 21
Attachments (Linked to Part, Supplier, Employee)
1:1VAIL-ERP document attachments (files linked to patients, encounters, suppliers, employees, inventory items) are exported as file metadata (file name, type, attached entity, date) alongside the files themselves. We reattach documents to the equivalent Epicor records (Part, Supplier, Employee) based on the attached-entity reference in VAIL-ERP. Documents attached to patient and encounter records cannot attach to a valid Epicor entity and are flagged for the customer's decision: archive, external document management, or a separate clinical system.
VAIL-ERP
Custom Fields
Epicor Prophet 21
UD Fields on IDO Collections
lossyVAIL-ERP custom fields (insurance codes, referral sources, clinical flags, and other per-organization attributes) are enumerated during the discovery phase by sampling records. We map discovered custom fields to Epicor UD (User-Defined) fields on the corresponding IDO collection (Part, Supplier, Employee). Healthcare-specific custom fields with no Epicor IDO target require a decision during scoping: create a custom UD table, map to an existing Epicor field, or archive. Custom field definitions discovered after the import mapping is finalized require a re-run of the affected module's import.
VAIL-ERP
Patient
Epicor Prophet 21
No Epicor equivalent
1:1VAIL-ERP patient records (demographics, encounter history, insurance details) have no direct Epicor ERP equivalent because Epicor is a manufacturing ERP without a clinical or patient management module. We flag this as a critical migration gap during scoping. Options include: archiving patient data to a separate HIPAA-compliant system before migration, keeping VAIL-ERP in read-only mode for clinical records, or integrating a dedicated healthcare CRM post-migration. We do not load patient records into Epicor ERP.
VAIL-ERP
Encounter
Epicor Prophet 21
No Epicor equivalent
1:1VAIL-ERP clinical encounters (encounter-type codes, provider assignments, timestamps, treatment plans) have no Epicor ERP equivalent. Encounter-to-patient linkage cannot be preserved in Epicor. If the customer requires encounter history for operational purposes (e.g., warranty claims on medical equipment), we map encounter summaries to Epicor Job records or a custom UD table; otherwise, encounter data is flagged for archival or exclusion.

Migration approach
Velosi data access coordination and discovery
We open a formal data access request with Velosi on the customer's behalf to obtain either a read-only database export or structured CSV package for each VAIL-ERP module. Simultaneously, we conduct discovery by reviewing VAIL-ERP module layouts, sampling records to enumerate custom field definitions, and mapping the organizational structure (departments, cost centers, sites). The discovery output is a written extraction plan listing each module, the export method, estimated record counts, and the custom field inventory.
Epicor Kinetic tenant provisioning and schema design
We assess the customer's Epicor Kinetic tenant for module availability (HCM, Financials, Supply Chain Management, Production Management) and configure the destination schema. This includes provisioning GL Account structure, Cost Center hierarchy, Supplier and Customer records (if applicable), Part and PartBin warehouse assignments, and UD fields for any mapped custom attributes. Schema is validated in a non-production Epicor environment before production data import begins.
Patient and encounter data decision
We present the customer with a documented decision framework for VAIL-ERP patient and encounter records: archive to a separate HIPAA-compliant repository, retain VAIL-ERP read-only post-migration, or integrate a dedicated healthcare CRM. The customer's decision is captured in writing before any import configuration begins. This decision gates the migration timeline because it affects downstream dependency mapping.
Sandbox migration and reconciliation
We run a full migration into the Epicor non-production environment using production-like data volume. The customer's operations lead reconciles record counts (employees, suppliers, parts, open AP/AR items), spot-checks 25-50 records against the VAIL-ERP source, and validates GL account distributions and cost-center assignments. Any mapping corrections happen in this phase. The customer signs off the sandbox migration before production migration begins.
Production migration in dependency order
We run production migration in record-dependency order: Cost Centers and GL Accounts first (reference data), then Employees and Users, then Suppliers and Customers, then Parts and PartBin inventory, then AP/AR open items, then GL journal entries, then document attachments. Each phase emits a row-count reconciliation report before the next phase begins. Custom UD field values load last after all parent records are in place.
Cutover, validation, and automation handoff
We coordinate a data-freeze window with the customer's VAIL-ERP team during cutover, run a final delta migration of any records modified during the window, then enable Epicor ERP as the system of record for migrated modules. We deliver a written inventory of VAIL-ERP workflows, automations, and custom reports that require rebuild in Epicor Kinetic. We support a one-week hypercare window where we resolve reconciliation issues. We do not rebuild VAIL-ERP automations as Epicor Kinetic processes inside the migration scope.
