The Teachers' Retirement System of Oklahoma (TRS) is undertaking a comprehensive, multiyear modernization initiative to replace aging legacy systems-including full retirement of the ALICE platform-and transition to a unified, cloud native environment. This effort centers on building MyPAS 3.0, a modern Azure-hosted pension administration system that integrates seamlessly with MyTRS and MyERS. TRS serves a large and diverse membership of over 210,000 employees and retirees across more than 600 school districts, career tech centers, colleges, and universities, making it the largest of Oklahoma's six state pension systems. The modernization responds to long standing challenges such as fragmented workflows, manual processes, limited scalability, and stability issues in legacy technologies. The initiative introduces a modern stack-Angular, REST APIs, Azure SQL Managed Instances, Azure Function Apps, Power BI, a document management and process automation solution (pending platform evaluation and alternatives)-to support scalable, secure, and efficient operations.
