Pre-Migration Planning Checklist
Start by documenting the existing GP environment and defining the target Business Central operating model. The project team should identify the legal entities, companies, modules, integrations, customizations, reports, workflows, and historical data that fall within migration scope.
- Define scope: Identify master data, open transactions, historical records, attachments, configurations, and reports that will be migrated or retained.
- Assign ownership: Establish business owners for finance, purchasing, sales, inventory, fixed assets, integrations, and reporting validation.
- Document dependencies: Record banking, payroll, CRM, ecommerce, tax, reporting, and other systems connected to GP.
- Set acceptance criteria: Define financial reconciliation thresholds, data completeness requirements, testing outcomes, and go-live approval conditions.

Data Preparation and Mapping Checklist
Data quality should be reviewed before extraction. Compare GP master records, identify duplicates, standardize formats, validate required fields, and remove records that are outside the agreed migration scope. Establish source-to-target mappings for every important data object.
- Master data: Validate customers, vendors, items, G/L accounts, dimensions, currencies, payment terms, and fixed assets.
- Financial data: Confirm trial balance, receivables, payables, inventory, bank balances, tax accounts, and other control totals.
- Historical data: Determine which transaction periods require direct migration and which records can remain available through an approved archive strategy.
- Transformation rules: Document account mappings, dimension conversions, field transformations, numbering structures, and currency handling.
For organizations with multiple finance structures, Central Finance is a useful related concept because it addresses standardized finance processes and information across entities or operating environments.
Business Central Configuration and Integration Checklist
Configure the Business Central environment before loading final production data. Review the chart of accounts, dimensions, posting groups, number series, currencies, payment terms, tax configuration, users, roles, approval workflows, inventory structures, and financial reports.
The Hyperbots Platform supports company-specific customizations involving ERP integration, workflows, roles, and GL structures through a no-code framework, which can be relevant when extending finance workflows around the new ERP.
Review every integration that will connect to Business Central. The ERP Integration Layer: How It Powers Finance Automation is relevant when planning how migrated finance information will flow between Business Central and connected applications using live ERP data.
Security should be validated before production use, including user access, authentication, integration permissions, segregation of duties, and audit requirements. ERP Security Best Practices for Finance Teams (2026) provides relevant guidance for cloud and hybrid ERP environments.
Testing and Reconciliation Checklist
Run trial migrations before the final cutover. Testing should verify that migrated records are complete, mapped correctly, and usable within Business Central. Finance users should validate representative transactions and confirm that reports produce expected results.
- Transaction testing: Test sales invoices, purchase invoices, receipts, payments, journals, inventory movements, and bank transactions.
- Financial reconciliation: Compare Business Central G/L balances against the approved GP trial balance.
- Subledger reconciliation: Verify accounts receivable, accounts payable, inventory, fixed assets, and other subsidiary ledgers against control accounts.
- Integration testing: Confirm data exchange between Business Central and connected applications.
- User acceptance: Obtain documented approval from finance and operational owners before production cutover.

Cutover and Go-Live Checklist
The final cutover should follow a documented sequence with clearly assigned responsibilities. Establish the final GP extraction point, control source-system activity as required, complete the final transformation and import, and perform production validation before releasing Business Central to users.
Confirm opening balances, open receivables, open payables, inventory, cash, fixed assets, tax balances, and other critical financial positions. Review user permissions and integrations immediately before go-live. The migration team should retain evidence of approvals, reconciliations, data loads, and exceptions.
For organizations operating internationally, finance teams should also verify currency configuration and exchange-rate procedures. This is especially important when migrated transactions and opening balances span multiple currencies.
Post-Migration Operations Checklist
After go-live, monitor financial posting, reporting, integrations, reconciliations, user access, and period-close activities. Establish a defined stabilization period during which finance and technical teams review migrated processes and resolve outstanding validation items.
Process Specific Capabilities can support process-specific AI automation trained on domain-relevant data across finance workflows. Ready to Deploy Capabilities provide pre-trained agents, ERP connectors, and no-code configurability for finance tasks, while Self Learning Capabilities enable workflows to learn from human actions and refine activities such as GL coding.
Human in the Loop approaches incorporate human oversight through exception escalation, approval workflows, and feedback, supporting controlled finance automation after the Business Central transition.
Organizations should also document migration evidence and operational procedures as part of their broader finance governance. A related Expatriate Checklist Finance may be relevant where international employee or cross-border finance processes form part of the wider financial operating model.

Final Validation and Best Practices
- Keep a signed migration record: Retain scope decisions, mappings, reconciliation results, approvals, and cutover evidence.
- Use business-owned validation: Have finance and operational users confirm that migrated information supports real business processes.
- Reconcile critical balances: Validate G/L, receivables, payables, inventory, cash, fixed assets, and tax balances.
- Review integrations continuously: Confirm that connected systems exchange accurate information with Business Central after go-live.
- Monitor reporting: Compare key financial reports against approved GP outputs during the transition period.
Summary
The Dynamics GP to Business Central Migration Checklist provides a practical control framework for moving from GP to Business Central while maintaining data quality, financial accuracy, integration readiness, and operational continuity. The checklist should cover planning, data preparation, mapping, configuration, testing, reconciliation, cutover, security, and post-go-live validation. Used consistently, it gives finance and project teams a clear method for confirming migration readiness and supporting reliable financial reporting and business performance.
