Legacy Modernization with Azure Cloud Migration Overview
OMI is a leader in Occupational Health, providing high-quality products, services, and continuing education to help companies meet OSHA compliance standards. From Pulmonary Function Testing to Hearing Conservation and Respirator Protection Programs, OMI
But behind the scenes, their digital infrastructure was on life support.
The Challenge: Legacy Systems, Serious Security Risks
OMI’s mission-critical applications were running on outdated, unsupported systems that posed increasing risks to cybersecurity and reliability.
Key Obstacles:
-
Outdated Microsoft Windows Servers using deprecated TLS 1.0 & 1.1, leaving web sessions highly vulnerable.
-
On-premise backup systems were time-consuming, with disaster recovery processes taking hours.
-
Unpatched MySQL databases with no recent updates pose an increased risk of data loss or corruption.
-
Legacy Adobe ColdFusion software required nightly reboots to remain operational and was becoming too costly.
It was clear that continuing down this path could compromise both data integrity and business continuity.
OMI needed a trusted partner to help them migrate legacy applications to the cloud, modernize their infrastructure, and minimize downtime.
They chose Tevpro.
Our Approach: From Fragile to Future-Proof
Tevpro’s goal was to secure OMI’s infrastructure, migrate them to the Microsoft Azure Cloud, and improve performance—all without disrupting ongoing clinical evaluations or user experiences.
Step 1: Secure Web Sessions with a Reverse Proxy
To immediately address the most critical security issues, we deployed a reverse proxy server in front of OMI’s legacy web servers. This created a secure buffer between users and the vulnerable backend systems.
-
SSL certificates were automated using Let’s Encrypt, eliminating the need for manual renewals.
-
This interim solution allowed us to keep the systems live and secure while working on full infrastructure modernization.
Step 2: Lift-and-Shift Migration to Microsoft Azure Cloud
We utilized a Lift and Shift strategy to migrate OMI’s legacy infrastructure from a Houston-based co-location facility into the Azure Cloud.
-
This instantly resolved hardware vulnerabilities and improved uptime.
-
Ensured a seamless transition with minimal disruption to end-users.
Step 3: Modernizing Databases and Software Stack
-
All MySQL databases were migrated to Azure Database for MySQL, resulting in reduced maintenance needs and enhanced scalability.
-
For the outdated ColdFusion application, we moved from Adobe ColdFusion to Lucee, an open-source CFML server.
This not only lowered licensing costs but also:
-
Improved performance
-
Reduced memory usage
-
Increased scalability for high-traffic systems
The Results: A Secure, Cost-Efficient, Cloud-Based Future
After successfully migrating to the Azure Cloud, the benefits to OMI were immediate and measurable.
Key Outcomes:
-
Cost savings through smaller, more efficient server instances
-
Faster application performance with Lucee replacing ColdFusion
-
Stronger security with encrypted sessions and up-to-date cloud infrastructure
-
No more reboots or manual service restarts
-
Automated backups and disaster recovery now built-in
-
Faster patching and update cycles with no downtime
-
SSL certificate renewals are free and fully automated
-
Significant reduction in infrastructure costs by eliminating the need for on-premise hardware
OMI’s IT and clinical teams now spend less time fighting fires and more time supporting business goals.
