The Challenge

A legacy warehouse and BI estate carries years of accumulated business logic embedded in stored procedures, report definitions and spreadsheets that no one has documented and few people still understand.

  • 1Business logic buried in undocumented stored procedures and report definitions
  • 2Rising licensing and infrastructure costs against degrading query performance
  • 3New data source requests quoted in months, so the business works around the platform

Our Approach

CloudGate begins with usage and dependency analysis to establish which reports genuinely matter and which logic must be preserved, then rebuilds on a Fabric medallion architecture with certified semantic models rather than lifting and shifting the accumulated mess.

  • Usage and dependency analysis establishing what is actually used before any migration
  • Business logic extraction from stored procedures and report definitions, documented as it goes
  • Medallion lakehouse rebuild on OneLake rather than a lift and shift of accumulated complexity
