A leading K12 courseware provider needed to migrate enterprise applications from on-premises and Oracle infrastructure to AWS Cloud and Aurora PostgreSQL. Challenges included large data volumes up to 5TB, complex codebases, job queue and SQL conversions, and performance benchmarks requiring <15ms response times. Aspire Systems used AWS SCT, DMS, and manual conversion to migrate 18,000+ tables with 12 billion rows, implementing partitioning, indexing, and tuning for optimization. The migration transferred 151.6TB of data in 11 months, saving $34.2M, improving scalability, and ensuring cost-efficient, high-performance operations.
