Enterprise migrations routinely run months behind schedule. Yours doesn't have to.
This guide is for VPs of IT, data architects, and migration leads at companies moving data from Microsoft Dynamics GP to Microsoft Dynamics 365 — whether you're scoping, planning, or mid-program.
Dynamics GP uses a proprietary Dexterity-based SQL Server schema with cryptic table names (RM00101 for customers, PM00200 for vendors, GL00100 for accounts) and a flat, wide-table design, while Dynamics 365 uses the Dataverse entity model or X++ data entities. Settle translates GP's legacy naming conventions to D365's modern entity framework automatically.

How Settle automates your Microsoft Dynamics GP to Microsoft Dynamics 365 migration
Settle auto-maps GP's cryptic table names (RM00101, PM00200, GL00100) to their D365 entity equivalents with field-level mapping — including GP's obscure column names like CUSTNMBR, VENDORID, and ACTINDX.
GP's work/open/history table split (GL20000 for current, GL30000 for history) is detected automatically. Settle generates migration rules that unify the data into D365's single-ledger model with proper period assignments.
Third-party ISV tables are profiled alongside GP core tables. Settle flags tables that belong to ISV modules (Mekorma, Binary Stream, SalesPad) and separates them from standard migration scope.
Settle validates the full GL-to-subledger reconciliation after migration — ensuring AR, AP, and inventory subsidiary balances match the general ledger in D365.

Common challenges migrating from Microsoft Dynamics GP to Microsoft Dynamics 365
GP's cryptic table naming to D365 entities
Dynamics GP uses non-descriptive table names inherited from its Dexterity origins — RM00101 (Customer Master), PM00200 (Vendor Master), GL00100 (Account Master), SOP10100 (Sales Transaction Work). Dynamics 365 uses descriptive entity names. Mapping between the two requires a crosswalk that covers hundreds of tables, and GP's documentation is notoriously sparse.

Companies must decide between Dynamics 365 Finance & Operations (enterprise-grade, X++ data model) and Business Central (mid-market, AL-based extensions). The data migration path differs significantly for each. Settle helps by profiling your GP data complexity to recommend the appropriate target and generating mappings specific to that platform.
Explore related migrations →Historical transaction migration and sub-ledger detail
GP stores financial history across work, open, and history tables (GL20000 for open year, GL30000 for history). Dynamics 365 uses different period-close and fiscal calendar models. Deciding how much history to migrate — and ensuring sub-ledger to GL reconciliation survives the transition — is a major decision point.
Explore related migrations →GP customizations and third-party ISV data
Most GP installations include third-party ISV modules (Mekorma for payments, Binary Stream for multi-entity, SalesPad for order management) that store data in custom tables alongside GP's core schema. These tables have no D365 equivalent and require individual analysis to determine what migrates, what gets archived, and what gets rebuilt.

The cost of manual Microsoft Dynamics GP to Microsoft Dynamics 365 migration
Dynamics GP to Dynamics 365 is one of Microsoft's most heavily promoted upgrade paths, and for good reason — GP has been in maintenance mode since Microsoft shifted investment to D365 Finance & Operations and Business Central. Companies on GP face dwindling support options, an aging Dexterity-based architecture, and an inability to integrate with modern cloud services. The migration is often timed with hardware refresh cycles or driven by the need for real-time reporting and API-based integrations that GP cannot provide.
Despite both being Microsoft products, the data architectures are fundamentally different. GP uses a proprietary Dexterity-based SQL Server schema with non-intuitive table names (RM00101 for customers, PM00200 for vendors, SOP10100 for sales orders) and a flat, wide-table design. Dynamics 365 uses the Dataverse entity model (for Business Central / CE) or normalized X++ data entities (for Finance & Operations). Field names, data types, and relational structures differ significantly — it's not a simple version upgrade but a full platform re-implementation.
Microsoft offers migration toolkits and ISV solutions (like eOne SmartConnect or Binary Stream), but these handle only standard modules. Companies with customized GP installations — which is virtually all of them — still face significant manual mapping, especially for modified reports, custom Dexterity tables, and third-party ISV data.
Consulting-led delivery for migrations in this class typically runs $600K–$1.5M. Settle prices it fixed and scoped — read the full cost breakdown.
