Case Study: Global Security and Transportation Company achieves nearly $1M/year licensing savings and enterprise HA/DR on SQL Server with DB Best Technologies

Migrating Critical Apps From Sybase ASE to SQL Server to Save Costs and Increase Support

Global Security and Transportation Company faced two mission‑critical but aging PowerBuilder applications running on out‑of‑support Sybase ASE with no adequate high availability or disaster recovery, and maintenance fees approaching $1 million per year. DB Best Technologies was engaged to modernize the platform, migrating the apps to SQL Server 2014 and updating PowerBuilder to a version that supports SQL Server connections.

DB Best Technologies implemented SQL Server 2014 Always On Availability Groups in a three‑node topology with readable secondary replicas to offload backups and reporting, preserving the existing user interface while adding HA/DR and improved performance. The migration eliminated additional licensing costs by leveraging corporate SQL Server licenses—reducing licensing TCO from approximately $900,000 per year to no additional cost—reduced development and testing effort, and delivered a compliant, future‑ready platform.
