The client is a US-based provider of DOT (Department of Transportation) and FMCSA (Federal Motor Carrier Safety Administration) compliance management solutions for transportation and logistics companies. Its platform supports driver qualification, compliance workflows, reporting and document management functions that carriers depend on to stay compliant and operational every day. When the client needed to move this entire platform off legacy, vendor-managed infrastructure and onto Microsoft Azure, they brought in Cloud 9 Infosystems to lead the Azure application migration and modernization effort.
Transportation & Logistics Compliance Software
Engagement: Legacy Application
Technology Stack: Microsoft Azure, IIS, PHP, MySQL, WordPress, SSL/DNS, Monitoring & Backup Services
Outcome: Full platform migrated to Azure improving security, resiliency and scalability.
A legacy platform running out of runway
The client’s business-critical application ecosystem was running on legacy infrastructure managed by a third-party hosting vendor. This ecosystem was not a single application but a tightly interconnected stack that included:
With the hosting vendor’s contract set to expire, the client faced a hard deadline to complete a full legacy application migration to Azure. That deadline came with a demanding set of constraints:
In short, this was a legacy system modernization challenge with a fixed deadline, minimal documentation, and zero room for disruption to a platform that transportation companies rely on for regulatory compliance.
A phased path from legacy to Azure
Cloud 9 Infosystems approached this as a phased Azure migration and modernization engagement, combining cloud infrastructure work with hands-on application remediation. The engagement moved through four stages: assessment and discovery, Azure migration, application stabilization and cutover with go-live support.
Before moving anything, Cloud 9’s team reviewed the legacy architecture and source code in detail. Because critical documentation was unavailable, the team conducted detailed application discovery and reverse engineering to uncover system dependencies, configuration requirements and operational workflows. This discovery phase mapped the infrastructure, application, database and dependency requirements needed to plan a safe and complete migration.
With a clear picture of the existing environment, Cloud 9 built dedicated Azure-based UAT and Production environments and migrated every component of the platform:
Alongside the migration itself, the team configured SSL, DNS, monitoring, and backup processes, and put a formal production cutover process in place, creating a structured and reliable Azure migration foundation that supported long-term operational stability.
Migrating the platform was only part of the job; making it stable and maintainable on Azure was the other. Cloud 9’s engineers replaced hardcoded production database references across approximately 65 files with environment-specific configurations, removing a significant source of operational risk and configuration complexity. The team also replaced at least one licensed WordPress plugin with custom PHP code, cutting a recurring third-party dependency and its associated cost.
During testing and UAT, Cloud 9 identified and fixed multiple defects, including:
This stabilization work was central to the application modernization effort — it addressed root-cause issues rather than simply relocating them to new infrastructure.
Cloud 9 developed detailed cutover and rollback plans to keep the production migration safe and reversible if needed, then executed the cutover with minimal disruption to the client’s business operations. After go-live, the team stayed engaged to provide post-go-live stabilization and support, resolving any issues that surfaced under real production conditions.
Measurable gains across the platform
The engagement delivered a complete legacy-to-Azure migration along with measurable improvements to the platform’s technical foundation:
