Sage 100 to Dynamics 365 Data Migration
Moving from Sage 100 to Business Central? Mine automates the mapping between Sage's module-based tables and D365's data entity framework — restructuring charts of accounts, customer records, and inventory for the Microsoft platform.

Most enterprise migrations start 6+ 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 Sage 100 to Microsoft Dynamics 365 — whether you're scoping, planning, or mid-program.
Sage 100 stores data in module-specific tables (AR_Customer, AP_Vendor, CI_Item, GL_Account) on Pervasive or SQL Server, while Dynamics 365 Business Central uses AL-based entities with posting groups, number series, and dimensional accounting. Mine translates Sage's on-premise ERP data to Business Central's cloud model automatically.

How Mine automates your Sage 100 to Microsoft Dynamics 365 migration
Mine analyzes Sage 100's chart of accounts and proposes the Business Central dimensional decomposition — splitting embedded segments into G/L accounts and dimension values based on naming patterns.
Posting group assignments are generated automatically — Mine analyzes Sage's transaction patterns to recommend Customer, Vendor, Inventory, and General posting groups with correct GL account linkage.
Multiple extraction formats supported — direct SQL Server access, Pervasive ODBC, or CSV exports. Mine profiles whichever format you can provide from Sage 100.
Mine validates trial balance reconciliation after migration — ensuring Sage 100 and Business Central balances match as of cutover date.

Common challenges migrating from Sage 100 to Microsoft Dynamics 365
Chart of accounts to Business Central dimensions
Sage 100 uses a flat or minimally segmented COA. Business Central uses G/L accounts with global dimensions, shortcut dimensions, and dimension values. The restructuring requires analyzing Sage's account naming patterns to identify embedded segments that should become dimensions.
Explore related migrations →Posting group configuration
Business Central uses posting groups (General, Customer, Vendor, Inventory) to control GL account assignment on transactions. Sage 100 assigns GL accounts directly on transactions. Setting up posting groups and mapping historical data to the correct posting logic requires careful analysis of Sage's transaction patterns.
Explore related migrations →Number series and document numbering
Sage 100 uses sequential numbering per transaction type. Business Central uses configurable number series with prefixes and gaps. Migrated documents must preserve original numbers while Business Central's series starts from the correct next value.
Explore related migrations →Inventory costing and tracking
Sage 100's inventory costing methods (FIFO, LIFO, Average, Standard) must map to Business Central's costing method field. Lot and serial tracking configurations differ between platforms. The valuation method must align before inventory data can load correctly.

|---|---|---|
| AR_Customer | → | Customer |
| AP_Vendor | → | Vendor |
| GL_Account | → | G/L Account + Dimensions |
| GL_DetailPosting | → | General Journal |
| CI_Item | → | Item |
| SO_SalesOrderHeader | → | Sales Order |

Typical enterprise migrations include 500K–10M+ records across these objects. Mine handles profiling and mapping at any scale.
The cost of manual Sage 100 to Microsoft Dynamics 365 migration
Companies typically manage this during a Business Central implementation using RapidStart Services or CSV imports. The posting group configuration and dimensional accounting setup are the most manual parts.
