Secure AI Migration from Legacy CRM to Predictive Forecasting Platform

Secure AI Migration from Legacy CRM to Predictive Forecasting Platform

A leading telecom provider based in Johannesburg, South Africa, managed millions of customer records and service logs through an on-premise CRM. As operations scaled, performance bottlenecks and data silos prevented efficient reporting and predictive forecasting. The organization partnered with our AI engineering team to execute a secure enterprise AI migration, connecting legacy infrastructure to a modern, cloud-based AI forecasting system via encrypted API middleware.
