Sybase to Microsoft SQL Server

Challenge

The airline industry is very time-sensitive. It depends on strong computer systems to manage flight operations effectively.

A major US airline company had been using Sybase ASE on Linux for years. However, they faced performance challenges and high overhead that were impacting their ability to maintain safe and efficient operations.

To address these issues, the company decided to migrate to Microsoft SQL Server. However, given the critical nature of their operations, minimizing downtime during the upgrade process was paramount.

To achieve this, they sought expert help to create a custom upgrade plan. This plan included a way to implement changes without any downtime, ensuring that airline services would continue without interruption.

Solution

To migrate Microsoft SQL Server in a mission critical operations environment, a carefully planned approach is essential. The main criterion was to minimize downtime (Zero Downtime) throughout the entire process.

The IT Manager decided that only the expert team in the industry could handle this critical job. They were referred to RalanTech for this role. RalanTech’s team worked closely with the client to create a smooth migration plan. This plan aimed to reduce downtime and keep the system safe. .

The team used a clear step-by-step method to move Sybase ASE to Microsoft SQL Server on the latest Linux platform.

Implementation Steps

  • Assess Current Environment and Goals:Evaluate existing Sybase Server configuration and define migration objectives.
  • Develop a Migration Plan:Identify critical systems, create a phased approach, and design a rollback plan.
  • Test and Validate:Set up a test environment and thoroughly test performance and compatibility.
  • Implement Upgrade in Phases:Prioritize systems, monitor closely, and address issues promptly.
  • Provide Training and Support:Ensure adequate training and support for staff.
