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 multiple service lines, time and materials billing, and regulatory compliance requirements, their ERP is not only a financial system — it is the backbone of project delivery and revenue recognition.
For many years, 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 — 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
Extraction of 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, with reconciliation checks at every stage of 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 reconciliation between SL and Business Central. Financial reports, project balances and GL accounts validated before cutover.

Migration Outcome

RJ Lee Group's migration from Dynamics SL to Business Central was executed with the precision their analytical services clients expect — with reporting continuity maintained through the transition.
