Data and Financial Assessment
The assessment should begin with a detailed inventory of the GP data landscape. Review customers, vendors, items, G/L accounts, dimensions, currencies, fixed assets, bank accounts, open transactions, historical transactions, attachments, and custom fields. Each data category should have an identified owner and a proposed target structure in Business Central.
Financial assessment should establish the quality and completeness of the source balances. Review the GP trial balance and reconcile key subsidiary ledgers, including accounts receivable, accounts payable, inventory, fixed assets, cash, and tax accounts. Historical reporting requirements should also be documented so the migration approach supports required financial comparisons.
An Interest Assessment can be considered a related finance concept when evaluating interest-related balances, calculations, or reporting requirements that may need to be preserved or redesigned during the transition.
Business Process and Customization Assessment
Review how GP supports daily finance and operational processes rather than evaluating data in isolation. Document order-to-cash, procure-to-pay, cash management, inventory, fixed assets, financial close, intercompany accounting, approvals, and reporting workflows.
GP customizations should be cataloged and classified according to whether equivalent Business Central functionality exists, a configuration change is appropriate, or a new extension or workflow is required. This approach helps prevent unnecessary replication of legacy structures.
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 assessing how finance workflows may be extended around Business Central.

Integration and Technical Assessment
Every existing GP integration should be documented, including its purpose, source and destination systems, data exchanged, frequency, authentication method, ownership, and business dependency. Typical integrations include banking, payment platforms, CRM, ecommerce, payroll, tax systems, warehouse applications, reporting platforms, and data warehouses.
The ERP Integration Layer: How It Powers Finance Automation is relevant to this assessment because the migration team needs to understand how Business Central will exchange live financial information with connected systems after GP is retired.
- Integration inventory: Identify every interface connected to GP and determine its future Business Central requirement.
- Data dependency analysis: Identify fields and transactions that must remain synchronized between Business Central and external systems.
- API and connector review: Determine appropriate integration methods for the target environment.
- Monitoring design: Define how successful exchanges, exceptions, and reconciliation results will be monitored.
Security and Compliance Assessment
Security assessment should review GP users, roles, permissions, segregation of duties, integration accounts, authentication practices, audit requirements, and sensitive financial information. Map these requirements to Business Central roles and access structures before migration.
ERP Security Best Practices for Finance Teams (2026) provides relevant guidance when evaluating security requirements for cloud ERP environments and integrations involving finance automation.
Compliance assessment should identify statutory reporting, tax requirements, audit evidence, document retention, and financial disclosure obligations. The assessment should document which compliance outputs must be reproduced in Business Central and which should be redesigned. This is particularly relevant to Central Finance initiatives where standardized financial information must support multiple entities or operating environments.
Business Central Readiness Assessment
The target Business Central environment should be evaluated against the requirements identified in the GP assessment. Review the chart of accounts, dimensions, posting groups, number series, currencies, payment terms, tax configuration, inventory settings, approval workflows, users, and financial reporting structures.
Migration readiness should also consider whether data mappings have been defined and whether cleansing rules are sufficiently mature for test migration. The team should establish measurable acceptance criteria for data completeness, financial reconciliation, transaction testing, reporting accuracy, and integration validation.
For organizations extending finance workflows after migration, Process Specific Capabilities can support process-specific AI automation trained on domain-relevant data. Ready to Deploy Capabilities provide pre-trained agents, ERP connectors, and no-code configurability for finance processes that are ready for deployment.
Assessment Outputs and Migration Roadmap
A completed assessment should produce practical outputs rather than only a list of observations. These outputs normally include a migration scope, data inventory, mapping requirements, customization assessment, integration inventory, security requirements, testing strategy, cutover considerations, and a prioritized action plan.
The assessment should clearly identify which GP data will be migrated directly, which data requires transformation, which functionality will be replaced by standard Business Central capabilities, and which requirements need extensions or integrations. This creates a traceable connection between current-state findings and the target-state design.
Self Learning Capabilities can support finance workflows that learn from human actions and refine activities such as GL coding. Human in the Loop approaches can incorporate human oversight, exception escalation, approval workflows, and feedback when designing controlled finance automation around the target ERP.

Best Practices for a Migration Assessment
- Use finance-led validation: Have accounting owners confirm the meaning and completeness of financial data before migration mapping is finalized.
- Separate data from functionality: Evaluate what information must move independently from which GP processes should be redesigned in Business Central.
- Document dependencies: Record integrations, custom reports, workflows, and external processes that depend on GP data.
- Establish reconciliation controls: Define how G/L, receivables, payables, inventory, cash, and fixed assets will be compared after test and production migrations.
- Maintain an audit trail: Preserve assessment decisions, ownership, mapping rules, approvals, and migration assumptions.
The assessment itself forms an important part of System Migration planning because it establishes the source-system baseline, target requirements, data decisions, and validation framework before execution begins.
Summary
Dynamics GP to Business Central Migration Assessment provides a structured view of the current GP environment and the requirements for moving to Business Central. It evaluates data, financial balances, business processes, customizations, integrations, security, compliance, target-system readiness, and migration dependencies. A well-defined assessment gives finance and technical teams the information needed to establish migration scope, prioritize preparation activities, and support accurate financial reporting and operational efficiency after the transition.
