Business Challenge

The airline industry is fast paced and relies on incredible computing power to maintain performance. This major US airline manages massive workloads on a 24/7 basis. The company had been operating Sybase ASE on Linux for years, but was in need of a system upgrade. In 2016, performance challenges and high overhead reinforced this need. The decision was made to upgrade to ASE 16 to improve high availability rates and system stability. In order to maintain services throughout the process, downtime needed to be minimized, so they needed help to devise a specialized upgrade strategy and implementation plan.


Their Director of IT knew the major challenge would be avoiding downtime throughout the process. They needed a Sybase expert to help plan and manage the project. The company's team reached out to SAP so that they could identify the best person for this critical job. They were referred to Peter Dobler and his company, Dobler Consulting. Dobler’s team worked hand-in-hand with the client to devise a strategy for the upgrade and migration that would minimize the downtime and maintain system fidelity. Through a phased approach, the system was upgraded to the ASE 16 and migrated to the newest Linux platform. Dobler also devised an extended Disaster Recovery (DR) plan to increase the system stability.


The migration and upgrade was so successful that the airline has continued to work with Dobler as a managed services client. Dobler Consulting maintains the system for continually smooth upgrades and routine IT processes. Since the migration, their system is now far ahead of the game. With high availability on both the application and database levels, they are able to support the continuous functions of the mission-critical systems. The improved architecture of the platform has allowed them to enjoy increased scalability that will last them for years to come.
