Migrating RJ Lee Group from Dynamics SL to Business Central
RJ Lee Group is a US-based analytical services firm providing scientific testing, materials characterization, and consulting services across multiple industries. With complex project accounting spanning dozens of service lines, time and materials billing, and regulatory compliance requirements, their ERP is not just a financial system — it is the backbone of project delivery and revenue recognition.
For over a decade, RJ Lee Group ran their operations on Microsoft Dynamics SL. The system was deeply embedded in their workflows, with customizations built over years of use. But with Microsoft ending mainstream support for Dynamics SL, the organization faced a clear decision: migrate to a modern platform now, or face escalating risk and cost on an increasingly unsupported system.
End-of-Life Urgency
Microsoft Dynamics SL mainstream support has ended. The partner ecosystem supporting SL is contracting rapidly — fewer consultants, fewer ISV add-ons, and increasing difficulty finding qualified resources. Every quarter on SL increases migration risk and cost.
Migration Approach
Econix designed and executed a structured migration from Dynamics SL to Business Central, with particular focus on preserving the complex project accounting workflows that RJ Lee Group depends on for daily operations.
Data Migration
Complete extraction of all financial data from Dynamics SL — general ledger, accounts payable, accounts receivable, project accounting, vendor and customer masters, and historical transactions. Custom migration tools built to handle SL-specific data structures and ensure 100% fidelity in the transfer.
Project Accounting Rebuild
Rebuilt project accounting workflows to leverage Business Central's native project management capabilities. Time and materials tracking, project billing, work-in-process accounting, and revenue recognition configured for RJ Lee Group's specific service line structure.
System Integration
Integrated Business Central with existing laboratory management systems and document management platforms. API-based integrations replacing the file-based and manual processes used with Dynamics SL.
Parallel-Run Validation
Ran both systems in parallel during the transition period with full reconciliation between SL and Business Central. Every financial report, every project balance, every GL account validated before cutover. Zero exceptions at go-live.
