SAP to Dynamics 365 Migration Case Study

The Challenge

The client was running SAP ECC 6.0 with extensive customisations built over 15 years. With SAP's 2027 end-of-support deadline approaching, the annual licence and maintenance costs had become unsustainable at over £350,000 per year. Key challenges included:

• Over 200 custom ABAP reports that needed to be replicated or replaced
• Complex manufacturing processes including batch production, quality management, and lot traceability
• Integration with 8 third-party systems including MES, WMS, and EDI
• Zero tolerance for production downtime during migration
• Tight 12-week deadline to align with fiscal year-end

The Solution

Pargesoft deployed its Agentic Migration methodology, using AI to accelerate every phase of the project:

• AI Data Mapping: Machine learning models analysed SAP data structures and automatically mapped them to D365 entities, reducing manual mapping from 6 weeks to 5 days.
• Automated Testing: AI-generated test scripts covered 97% of business scenarios, with continuous regression testing throughout migration.
• Parallel Running: Both systems ran simultaneously for 3 weeks with AI agents reconciling transactions in real time.
• Agent Deployment: 5 AI agents deployed at go-live: invoice processing, demand forecasting, quality alerting, inventory optimisation, and vendor performance monitoring.

The Results

Within 90 days of go-live, the client achieved measurable results across every dimension:

• 30% cost reduction in total ERP operating costs, saving over £105,000 annually
• 92% of manual processes automated through AI agents and Power Automate flows
• Month-end close reduced from 8 days to 2 days with AI-assisted reconciliation
• Inventory accuracy improved from 91% to 99.2% with real-time tracking
• Zero production downtime during the entire migration and cutover process
