The Challenge
Apex Manufacturing was running a 15-year-old .NET Framework 3.5 ERP on ageing on-premise hardware. The system suffered frequent downtime (avg. 4 hrs/month), could not scale during month-end peaks, and had no disaster recovery capability. Hardware refresh would cost ₹2.5 Cr — and not solve the scalability problem.
Our Solution
VFL Technologies conducted a 2-week Azure Migration Assessment, then executed a phased lift-and-refactor migration. We migrated the SQL Server 2008 database to Azure SQL Managed Instance using DMS in continuous sync mode, modernized the .NET 3.5 application to .NET 8, containerized services with Docker, and deployed to Azure Kubernetes Service with auto-scaling.
