MIGRATION OVERVIEW

Why teams migrate from Microsoft Dynamics GP to Dynamics 365 Business Central

Migrating from Dynamics GP to Business Central is a structural translation from a segmented, on-premise Dexterity-based ERP to a cloud-native, dimension-based AL platform — not a lift-and-shift. Microsoft provides a native Cloud Migration Tool, but it only migrates summary GL transactions for historical years; detailed transaction history is pushed to extension tables outside the live BC ledger, requiring custom Power BI or Power Apps builds for access. Successful migrations demand a tiered data strategy — live transactional data into BC, historical snapshots into extension tables, and 5–25 years of legacy detail into SQL archives or Azure Data Lake — along with significant reconciliation work to address sub-ledger drift, segment-to-dimension mapping, and data integrity issues accumulated over decades in GP.
KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a Microsoft Dynamics GP to Dynamics 365 Business Central migration.

Most Critical

Segment-to-Dimension Structural Translation

GP's account segment structure must be mapped to Business Central's dimension-based chart of accounts, requiring a complete rethinking of how financial reporting hierarchies are constructed.

Historical GL Detail Loss

The native Cloud Migration Tool only posts summary GL amounts for historical years, pushing detailed transaction history into extension tables that are not queryable through the standard BC interface.

Sub-Ledger Contamination from Legacy Data

Decades of manual journal entries to control accounts, orphaned transactions, and voided-and-reissued checks cause GL drift from AR/AP sub-ledgers that must be reconciled before migration.

Undeposited Cash Receipt Risk

The native tool does not migrate undeposited cash receipts, so all posted receipts must be deposited in GP before the final migration run or bank reconciliation will drift immediately at go-live.

Partial Payment Invoice Translation

Outstanding receivables and payables migrate with remaining balances only — partially paid invoices come across at net rather than gross, losing the original transaction detail and payment history.

Long-Term Archive Accessibility

Ensuring 10–25 years of historical GP data remains queryable for auditors post-cutover requires building and maintaining a separate archive infrastructure such as a read-only SQL instance or Azure Data Lake.

MIGRATION RISK ASSESSMENT

Every migration risk, already solved

Migration between platforms is full of edge cases. Our engineers have identified every risk from Microsoft Dynamics GP to Dynamics 365 Business Central and built proven solutions for each one.

Migration Challenge ClonePartner Status
High Complexity —
Solved
Chart of Accounts
GP's segmented account structure must be fundamentally redesigned into BC's dimension-based model, requiring careful mapping to preserve reporting integrity.
Solved
General Ledger History
Only summary GL balances migrate into the live BC ledger; detailed historical transactions are relegated to extension tables requiring custom reporting builds.
Solved
Bank Reconciliation Data
Only the most recent reconciled balance and outstanding items migrate, and undeposited receipts must be manually cleared in GP before cutover to prevent day-one drift.
Solved
Historical Closed Transactions
Closed AP/AR transactions and paid vendor invoices spanning 10–25 years do not migrate into live BC and must be archived in SQL, Azure Data Lake, or extension tables with custom access layers.
Solved
Custom Engineering —
Handled
Open Accounts Payable
Open AP invoices migrate at remaining balance only, losing partial payment history and requiring pre-migration reconciliation to ensure sub-ledger alignment.
Handled
Open Accounts Receivable
Outstanding AR invoices migrate at net remaining amounts, and undeposited cash receipts are excluded entirely, creating reconciliation risk at cutover.
Handled
Inventory and Item Data
On-hand quantities and serial/lot data migrate, but historical costing layers and transaction history from GP's inventory module require separate archival.
Handled
Check Images and Supporting Documents
Scanned checks, invoice images, and supporting documentation stored outside GP's SQL tables require a separate document repository migration and linking strategy.
Handled
Clean Transfer
Customer and Vendor Master Data
The native tool supports active/inactive filtering for customers and vendors, making master data migration relatively straightforward.
Clean
Open Purchase Orders
The native migration tool supports open purchase order migration, though partially received POs should be verified for quantity and amount accuracy post-migration.

What does an Engineer-led migration mean anyway?

Speed & Accuracy: Our Blended Method

We blend automation (smart scripts, bulk APIs) with human expertise for speed without risk. Our engineers manually check every mapping, validation, and exception.

You get:

  1. Speed of automation for bulk record migration
  2. Precision of engineers verifying integrity and business logic
  3. Pilot migrations and sandbox testing to catch issues early
  4. Real-time validation reports and rollback readiness
Result: 50x faster migrations than manual imports — with near-zero error rates.

Handling the Tricky Tech and API Details

The Microsoft Dynamics GP and Dynamics 365 Business Central APIs each behave differently, which is where our engineers shine. We build custom logic to handle the data quirks where generic tools typically break.

We handcraft API logic for:

  1. Field mapping and transformation
  2. Pagination, rate-limit handling, and throttling
  3. Preserving conversation threads, attachments, and internal notes
  4. Syncing custom fields, SLAs, and macros without breaking structure
Our scripts: Natively retry failed calls, re-queue large attachments, and ensure data parity.

No Guesswork

We don't just promise smooth migrations—we measure and prove them. Every client receives a Migration Validation Report with all metrics.

Typical results across projects:

  1. 100% record-count parity between your Microsoft Dynamics GP data and Dynamics 365 Business Central
  2. Zero downtime during staged cutovers
  3. 99.9% attachment integrity (verified via checksum)
  4. Full automation and preservation of all business rules
Our standard: Includes full SLA preservation and 48 hours of engineer-assigned support post go-live.

We Adapt to Your Setup (Not the Other Way Around)

No two teams configure Microsoft Dynamics GP or Dynamics 365 Business Central exactly the same way—with unique automations and data. We customize every migration script to fit your exact workflow, tags, and triggers.

Our engineers adapt for:

  1. Custom fields, ticket forms, and workflows
  2. Multi-brand or multi-language setups
  3. Historical imports and partial (date-based) migrations
  4. Integration re-mapping for CRMs, chat, or feedback tools
The promise: If your data doesn't fit a standard template, we build one just for you.
