Business Central Migration Checklist

A safe Business Central migration needs five things verified before cutover: clean master data, a signed-off chart of accounts and dimension design.

The short answer

A safe Business Central migration needs five things verified before cutover: clean master data, a signed-off chart of accounts and dimension design, a reconciled sandbox month-end close, rebuilt reporting on live data, and a rehearsed cutover plan with a data freeze and named owners. Skipping any one of them is what turns a scheduled go-live into a recovery project.

01

Before configuration begins

  • Written process maps for quote to cash, purchase to pay and production
  • Decision on which processes change at go-live
  • Chart of accounts and dimension design signed off by finance
  • Inventory of every integration and report, marked keep, replace or retire
  • Agreement on how many historical years migrate
02

Master data readiness

  • Items de-duplicated with standardized numbering and units of measure
  • Customers and vendors de-duplicated with validated tax setup
  • BOMs and routings validated against actual production
  • Costing method assigned per item category
  • Opening inventory quantities physically counted, not assumed
03

Verification gates

  • Scripted end-to-end tests using real documents
  • Sandbox month-end close reconciled to the legacy system
  • Negative-path testing: returns, scrap, credit holds, partial shipments
  • Power BI or financial reports rebuilt and matching known numbers
  • Permission sets tested per role, including approval limits
04

Cutover mechanics

  • Period-boundary date with a documented freeze window
  • Verified opening balances and open document load
  • Reconciliation sign-off before transacting
  • Named owner per workstream during the freeze
  • Rollback criteria defined in advance, in writing
05

First thirty days

  • On-floor support at shipping, receiving and production posting
  • Daily reconciliation of inventory movements for the first two weeks
  • Ticket triage path for ERP-specific issues
  • License assignment review once real usage is visible
  • Backlog review of deferred requests, prioritized against business impact

Common mistakes

What goes wrong most often.

  • Cutting over mid-period
  • Loading opening inventory without a physical count
  • No documented rollback criteria
  • Reporting rebuilt after go-live rather than before

Common questions

Straight answers, no sales theater.

How much history should we bring?

Balances plus one to two years of transactional detail suits most companies. Keep the legacy system read-only or archive it for older years — migrating everything adds cost and risk with little operational value.

Do we need a parallel run?

A reconciled sandbox month-end close plus scripted end-to-end testing usually substitutes for a full parallel run at mid-market scale, and costs far less in staff time.

What is the biggest cause of overrun?

Master data quality, followed by integration count. Neither is discovered late in projects that inventory both before configuration starts.
