Database Modernization From Mysql To Snowflake

A US-based lead generation agency was operating on an on-premise MS SQL Server originally built for transactional workloads, which had increasingly been used for reporting and analytics.

Challenge:

  • Limited scalability and high fixed infrastructure costs
  • Complex legacy schemas with undocumented SQL logic
  • Slow turnaround for new analytics and reporting needs

Approach:

  • Assessed existing SQL schemas, workloads, and critical reports
  • Designed a Snowflake-based data warehouse optimised for analytics
  • Migrated historical and incremental data from SQL Server to Snowflake
  • Refactored SQL logic into Snowflake-native transformations
  • Enabled role-based access and BI tool integration
  • Ran systems in parallel to validate data accuracy before cutover

Outcome:

  • Elastic, on-demand compute for reporting and ad-hoc analysis
  • Reduced infrastructure and licensing costs through a pay-per-use model
  • Faster and more reliable analytics delivery
  • Scalable foundation for advanced analytics and data science
