What Next Pathway's Fortune 500 Financial Services Company Case Study covers
A Fortune 500 Financial Services Company migrated Netezza, SSIS, DataStage, and Informatica to Snowflake. Next Pathway's automation platform delivered 100% automated code translation, conversion of 5,800+ ETL pipelines, and retirement of the legacy Netezza environment within six months.
Automated Large Scale Code Conversion
Next Pathway automated the translation of more than 600,000 lines of Netezza SQL and stored procedures for Snowflake. Over 5,800 DataStage and Informatica ETL pipelines were converted and optimized for Snowflake execution, reducing manual effort and accelerating delivery timelines.
Seamless Migration with Zero Business Disruption
All ETL pipelines and BI reports were migrated and operational in Snowflake without disrupting ongoing business operations. Hundreds of BI report queries were repointed to the new Snowflake environment, supported by QA, parallel run support, training, and documentation for internal teams.
Legacy Platform Retirement and Cloud Modernization
The company fully retired its legacy Netezza environment within six months, eliminating the need for costly license extensions. With workloads running on Snowflake, the organization now operates on a scalable cloud native platform designed to support advanced analytics, agility, and future growth.

What a structured Snowflake migration covers
A successful migration to Snowflake requires a clear plan across four disciplines.
Discovery and dependency mapping
Every code object, ETL pipeline, and data dependency needs to be identified and documented before migration begins. Hidden complexity discovered mid-migration creates delays and risk.
Code translation and modernization
Legacy SQL, stored procedures, and ETL pipelines must be converted into optimized, Snowflake-native workloads. Automated translation eliminates manual rework and ensures full coverage.
Validation and functional parity
Every migrated workload must be validated against the legacy source to confirm data accuracy and functional equivalence before cutover. 100% parity is not optional.
Production cutover planning
Cutover requires a defined plan covering resource allocation, rollback decisions, and business sign-off. Teams that plan cutover from the start move faster and with greater confidence.
