Managed Epicor Prophet 21 Migration & Ongoing Data Sync

Migrate your data 3 to 4 weeks before go-live, incrementally and in parallel with normal operations. Cut go-live risk, compress timelines, and walk into cut-over with data already proven in Prophet 21.

What Sets ESS Apart

Don't Wait for Go-Live to Migrate Your Data

Most ERP projects pile migration into a single stressful cut-over weekend. ESS flips the model. Your data is migrated incrementally, starting 3 to 4 weeks before go-live, so by the time you cut over, the data is already in Prophet 21, validated, reconciled, and ready.

Start 3 to 4 Weeks Early

Kick off migration while your legacy ERP is still running. No downtime, no business disruption, no waiting for a freeze window.

Incremental, Not Big-Bang

Load master data first, then deltas daily or weekly. Every pass reduces the surprise surface area on cut-over day.

Lower Risk, Shorter Timelines

Data issues surface weeks early while there's time to fix them. Cut-over becomes a verification step, not a migration sprint.

Traditional Cut-Over vs. The ESS Approach

Traditional
  • • All data migrated over a single weekend
  • • Issues discovered under time pressure
  • • Business operations on hold during cut-over
  • • High risk of go-live slippage
ESS Approach
  • • Migration begins 3 to 4 weeks before go-live
  • • Data issues found and fixed early, with time to spare
  • • Legacy system keeps running in parallel
  • • Cut-over is a final delta and a sign-off, not a sprint

Two Capabilities, One Platform

Master data migration is standard in the product. Dynamic data integration is built to your requirements, because every customer's data landscape is different.

Built-in with the product

Master Data Migration

All the standard domains your distribution business runs on are covered out of the box: items, customers, suppliers, open orders, financials, and inventory counts.

Extract, stage, review, and promote, through the same portal your team will use long after go-live.

Custom built per customer

Dynamic Data Integration

Requirements differ significantly by customer. ESS extends the same tooling with integrations built specifically for your CRM, EDI partners, carriers, finance systems, eCommerce, and custom portals.

You get the reliability of a shared platform, with the fit of a bespoke build.

The Challenge

Legacy data, live operations

Distributors replacing A+, Baan/Infor, or Macola can't afford a messy cut-over. Master data, open orders, receivables, and cycle counts must survive the move, and the systems your customers and partners rely on, including CRM, EDI, and shipping portals, need to stay in sync from day one.

The Approach

Business-led, not ticket-led

ESS runs migration and ongoing sync through a single guided portal your team owns. Data is reviewed, fixed, and promoted by the people who know it best, with validation, retry, and live visibility built in.

How the Migration Runs

Six repeatable stages take your data from legacy extract all the way through to ongoing sync, with your team in the driver's seat at every step.

01

Extract from Legacy

We connect to A+, Baan, Macola, or pull flat Excel, Access, and CSV exports, using proven templates that capture master and transactional data completely.

02

Stage & Validate

Every record lands in a Prophet 21 shaped workspace where ESS validates structure, keys, and business rules before anything touches your live system.

03

Review in Your Portal

Your team logs into the ESS web portal to inspect and fix records, run bulk edits, and sign off on each domain, with no SQL or tickets required.

04

Migrate in Bulk

Validated data is promoted into Prophet 21 in idempotent batches. If something fails, only the failed rows requeue, so successful rows are never duplicated.

05

Track Status Live

Real-time dashboards show synced, pending, and failed counts per domain, with one-click drill-down to the exact record and error.

06

Keep Systems in Sync

After go-live, ESS continues to detect and push updates to the downstream systems you rely on, so Prophet 21 stays the single source of truth.

Standard in the product

Master Data We Move Out of the Box

Every core domain your distribution business runs on is covered, validated, and reconciled before it lands in Prophet 21.

Item & Product Master

Items, suppliers, units of measure, locations, accessories, pricing, and notes, validated and ready to trade on day one.

Customers & Ship-Tos

Customer accounts, addresses, ship-to networks, customer part numbers, and contact notes, with nothing lost in translation.

Suppliers & Vendors

Alternate suppliers, vendor addresses, and supply terms, mapped to your new procurement workflows.

Financials

Open AR, open AP, closed invoices, and GL journal entries, reconciled against your legacy trial balance.

Open Orders

In-flight sales orders and purchase orders, header and line, so shipments and receipts continue uninterrupted.

Inventory Counts

Bin, item, lot, and serial counts, so your warehouse starts accurate in Prophet 21 from the first pick.

Built to your requirements

Dynamic Data Integration

Every customer's data landscape is different. Your partners, trading documents, tax rules, and downstream systems are unique, so the integrations on top of Prophet 21 have to be too. ESS builds these onto the existing migration and sync tooling, so new integrations reuse the same portal, status dashboards, retry logic, and audit trail your team already knows.

Two-way sync with your CRM (Salesforce, HubSpot, or custom)
EDI partner onboarding and trading document exchange
Shipping and carrier integrations for rates, labels, and tracking
Finance, tax, and payment gateway connections
eCommerce storefront catalog, inventory, and order sync
Custom supplier or customer data portals specific to your workflows

Examples shown are representative. Every dynamic integration is scoped and built to fit your specific data, volumes, and workflows.

What Your Team Uses Every Day

The ESS web portal makes migration and ongoing sync part of normal operations, owned by the business, supported by ESS.

Self-Service Bulk Upload

Your data stewards drop CSV or Excel files into the portal and watch them load, validate, and stage, with no developer in the loop.

Live Status Dashboards

See at a glance how many items, customers, vendors, and orders are synced, pending, or failed, and drill from summary to the exact row.

Safe Re-Run & Retry

Fix a bad row, click retry, and only that row re-posts. Successful records are never re-sent, so you can iterate without fear.

Role-Based Access

Give AR, AP, warehouse, and sales leads access only to the domains they own, with full audit trails on every change.

Scheduled Runs & Alerts

Schedule recurring migration and sync jobs, and get notified by email or in-app when a run completes or a threshold is breached.

Audit-Ready Exports

Download pre and post-migration snapshots of every domain for finance, compliance, and reconciliation sign-off.

Why It Works for the Business

Start migrating 3 to 4 weeks before go-live, with your legacy ERP still running
Go live on Prophet 21 without pausing shipments, invoicing, or receiving
Keep finance reconciled, with open AR, AP, and GL matching your legacy trial balance
Hand data ownership to the business, not IT, through a guided web portal
Cut rework with validation that catches bad data before it hits Prophet 21
See exactly where every record stands, with no more spreadsheets tracking spreadsheets
Extend the same tooling into custom integrations shaped to your business

Migration Doesn't End at Go-Live

After cut-over, the same portal keeps Prophet 21 in sync with the rest of your business. Master data sync runs as standard, and any dynamic integrations we've built for you run on the same rails. You get one place to manage ongoing data flow, one team to call when something needs attention, and one source of truth across the company.
