Data and Financial Requirements
The first requirement is a clear inventory of the data that will move from GP into Business Central. The migration team should classify information as master data, open transactions, historical transactions, configuration data, or archived information. Each category should have an identified source, target structure, owner, and validation method.
- Master data: Customers, vendors, items, G/L accounts, dimensions, currencies, payment terms, and fixed assets.
- Financial balances: Trial balance, accounts receivable, accounts payable, inventory, cash, fixed assets, tax accounts, and retained earnings.
- Open transactions: Unpaid invoices, outstanding credit memos, purchase documents, sales documents, and other transactions requiring continued processing.
- Historical information: Define the periods and transaction details required for statutory, management, audit, and comparative reporting.
Currency requirements should also be documented, including base currency, additional currencies, exchange-rate procedures, and historical reporting needs. Finance teams should establish appropriate controls around E Invoice Requirements where electronic invoicing forms part of the organization's invoicing and compliance processes.
Business Central Configuration Requirements
Business Central should be configured to reflect the organization's approved financial and operational model before final production data is loaded. Key requirements include the chart of accounts, dimensions, posting groups, number series, currencies, payment terms, tax settings, inventory structures, approval workflows, users, and financial reporting configurations.
The Hyperbots Platform supports company-specific customizations involving ERP integration, workflows, roles, and GL structures through a no-code framework. Such capabilities can be considered when defining requirements for finance workflows surrounding the target ERP.
Migration requirements should also account for processes that are being redesigned rather than copied directly from GP. ERP Modernization vs Finance Automation: Key Differences provides relevant context when separating ERP modernization requirements from improvements to finance execution.
Integration and Technical Requirements
Every system connected to GP should be reviewed to determine whether it will remain, be replaced, or be integrated with Business Central. Common dependencies include banks, payment platforms, CRM systems, ecommerce applications, payroll, tax services, reporting tools, warehouse systems, and external data platforms.
The ERP Integration Layer: How It Powers Finance Automation is relevant when defining how Business Central will exchange data with connected applications and how migrated finance information will support ongoing workflows.
- Integration inventory: Document each interface, data owner, frequency, direction, authentication method, and business purpose.
- API and connector requirements: Establish supported integration methods and required data fields.
- Environment requirements: Separate development, testing, and production activities where appropriate.
- Monitoring requirements: Define procedures for reviewing successful data exchange and resolving exceptions.
Security, Compliance, and Reporting Requirements
Security requirements should cover Business Central users, roles, permissions, authentication, segregation of duties, integration accounts, and audit trails. Access should be aligned with job responsibilities so finance and operational users receive the appropriate level of system access.
ERP Security Best Practices for Finance Teams (2026) is relevant when establishing security requirements for cloud ERP environments and integrations involving finance automation.
Reporting and compliance requirements should also be documented before migration. Identify statutory reports, management reports, financial statements, tax reports, audit evidence, and comparative reporting requirements that must be reproduced or redesigned in Business Central. Disclosure Requirements are particularly relevant where financial reporting outputs must support defined disclosure obligations.
Testing and Validation Requirements
A migration should have documented acceptance criteria before production cutover. Testing should confirm that data is complete, mappings are correct, transactions behave appropriately, integrations operate as expected, and financial balances reconcile between GP and Business Central.
- Data validation: Confirm record counts, mandatory fields, mappings, and transformed values.
- Functional testing: Test sales, purchasing, receivables, payables, inventory, banking, journals, and other core workflows.
- Financial reconciliation: Compare the Business Central trial balance and subsidiary ledgers with approved GP balances.
- User acceptance testing: Have finance and operational owners validate representative business scenarios and reports.
Organizations can also define process-level automation requirements during testing. Process Specific Capabilities support process-specific AI automation trained on domain-relevant data, while Ready to Deploy Capabilities provide pre-trained agents, ERP connectors, and no-code configurability for finance tasks.
Operational and Go-Live Requirements
The organization should define responsibilities and approvals for the final migration. This includes the final GP extraction date, data freeze procedures, production import sequence, reconciliation responsibilities, user provisioning, integration activation, and go-live approval.
Post-go-live requirements should cover financial close, reconciliation, reporting, integration monitoring, user support, and ongoing data governance. Self Learning Capabilities can support workflows that learn from human actions and refine activities such as GL coding, while Human in the Loop incorporates human oversight, exception escalation, approvals, and feedback into finance automation.
For organizations with specialized operating models, ERP for Retail Industry: 2026 Guide to Platforms & AI can provide additional context when Business Central migration requirements include retail-specific ERP processes and AI-enabled finance workflows.
Governance and Finance Requirements
Governance requirements should establish who owns migration decisions, data approvals, reconciliation sign-off, security validation, and post-go-live controls. This is especially important when several legal entities, currencies, or finance teams are involved.
Central Finance is a related finance concept for organizations seeking standardized financial processes and information across entities. Migration requirements should also consider how accounting policies, reporting structures, tax processes, and management reporting will operate after consolidation into Business Central.
Documenting requirements before execution creates a common reference point for project teams and finance stakeholders. It also helps ensure that migration decisions remain aligned with financial reporting, operational efficiency, compliance, and business performance objectives.
Summary
Dynamics GP to Business Central Migration Requirements establish the conditions needed for a controlled and financially accurate ERP transition. They cover data scope, financial balances, Business Central configuration, integrations, security, compliance, reporting, testing, governance, and go-live readiness. Defining these requirements early gives finance and technical teams a shared framework for validating the migration and establishing Business Central as a reliable foundation for financial reporting and operational efficiency.
