What Post-Migration Reconciliation Covers
A complete reconciliation should cover both summary-level financial balances and detailed operational records. The scope depends on the migration strategy, historical data requirements, number of companies, and transaction types transferred into Business Central.
- General ledger: Compare trial balances, account balances, dimensions, retained earnings, and opening entries.
- Accounts receivable: Reconcile customer balances, open invoices, credits, receipts, and aging information.
- Accounts payable: Compare vendor balances, open invoices, credits, payments, and aging reports.
- Inventory: Validate item quantities, locations, valuation, costing, and inventory-related ledger balances.
- Cash and banking: Compare bank balances, outstanding transactions, and relevant reconciliation information.
- Fixed assets and other modules: Validate balances and supporting records where those areas were included in the migration.
How the Reconciliation Process Works
The process normally begins by establishing approved Dynamics GP closing balances as the source baseline. The migration team then extracts corresponding Business Central balances and compares them using consistent company, account, period, currency, dimension, and transaction criteria.
Differences should be categorized rather than treated as a single variance. A difference may arise from a legitimate mapping change, a timing difference, a conversion rule, a rounding adjustment, or an item that was intentionally excluded from the migration scope. Each material variance should have an explanation and an approved resolution.
The Post Migration Reconciliation glossary concept provides useful terminology for understanding this control activity, while the broader Central Finance concept helps organizations consider how standardized financial information can be governed across business operations.
Key Reconciliation Checks
Effective reconciliation combines control totals with transaction-level validation. For example, the total accounts receivable balance in Business Central should be compared with the approved Dynamics GP closing balance, followed by checks of customer-level balances and selected transaction details.
- Compare the Dynamics GP and Business Central trial balances for the migration cutover period.
- Reconcile subledger totals to their corresponding general ledger control accounts.
- Compare open customer and vendor documents using document number, amount, currency, and status.
- Validate inventory quantities and values by item, location, and relevant costing structure.
- Review migrated dimensions and account mappings used in financial reporting.
- Confirm that bank and cash balances agree with approved migration records.
For organizations extending Business Central with connected finance workflows, the ERP Integration Layer: How It Powers Finance Automation provides relevant context on maintaining reliable ERP data exchange around a migration.
Automation and Exception Management
Post-migration reconciliation can be incorporated into repeatable finance workflows. The Hyperbots Platform supports company-specific configurations involving ERP integration, workflows, roles, and GL structures, while Process Specific Capabilities can align automation with defined finance processes and domain-specific workflows.
Ready to Deploy Capabilities can support finance teams with pre-trained agents, ERP connectors, and configurable workflows. Self Learning Capabilities can use human actions to refine workflows and improve GL coding over time. Where reconciliation produces exceptions requiring judgment, Human in the Loop supports human review, approval workflows, and feedback within finance processes.
Controls, Security, and Reporting
Reconciliation results should be documented with the source report, Business Central report, comparison criteria, variance amount, explanation, owner, and resolution status. This creates an audit trail showing how the organization established confidence in migrated financial information.
Access to migration and reconciliation data should follow appropriate finance and ERP security controls. ERP Security Best Practices for Finance Teams (2026) provides relevant guidance for cloud and hybrid environments, including considerations for connected automation tools.
Organizations should also distinguish reconciliation from broader ERP transformation activities. ERP Modernization vs Finance Automation: Key Differences helps explain the relationship between modernizing an ERP platform and improving the execution of finance workflows around that platform.
Business Impact and Ongoing Validation
Accurate post-migration reconciliation gives finance leaders a dependable basis for reporting, close activities, budgeting, working-capital analysis, and management decisions. It also establishes confidence that operational records in Business Central support the financial statements and business processes expected after migration.
For organizations operating retail environments, ERP for Retail Industry: 2026 Guide to Platforms & AI provides additional context on ERP capabilities and finance automation within retail operations. Reconciliation should continue beyond the initial migration review through normal period-end controls and targeted validation of new transaction flows.
The Post Filing Reconciliation concept is also useful where financial records must be compared after a filing or reporting event, helping distinguish migration validation from subsequent compliance-oriented reconciliation activities.
Summary
Dynamics GP to Business Central Post-Migration Reconciliation verifies that Business Central accurately reflects approved Dynamics GP closing information and that migrated financial and operational records support reliable reporting. The process covers general ledger balances, subledgers, inventory, banking, dimensions, mappings, and other migrated data.
A disciplined reconciliation framework combines control totals, detailed comparisons, documented variance explanations, security controls, and appropriate human review. By embedding these practices into the post-migration operating model, organizations can establish dependable financial reporting and maintain data integrity as Business Central becomes the primary ERP environment.
