Database Migration and Application Modernization Case Study

This case study details the efforts of a global software solutions provider to modernize their property management system in response to evolving hospitality industry standards. The objective was to transition from MS SQL Server to AWS Aurora PostgreSQL while ensuring compatibility with existing systems. The migration involved rewriting over 1200 database objects and testing more than 300 application screens to ensure seamless integration and performance validation. The Xoriant team implemented an automated program to consolidate TSQL for procedures and functions, which significantly reduced script creation time and manual debugging efforts. The use of open-source tools enhanced productivity and issue resolution. The project resulted in a 50% reduction in manual efforts and a substantial decrease in debugging time from hours to minutes. The case study highlights the challenges faced and the solutions developed to achieve a successful database migration while maintaining operational continuity.
