Airflow Version Upgrade for Enterprises: A Practical Blueprint for AWS, Snowflake, dbt, and Fintech Data Platforms

Short summary

Enterprise Airflow upgrades require careful dependency pinning with constraints files, metadata database snapshots, and comprehensive DAG validation in CI before production. Use reproducible containers with explicit provider versions and test extensively, especially for Airflow 3.x which introduces breaking changes. This is critical for regulated fintech environments managing Snowflake, dbt, and AWS integrations.

• •Use constraints files and explicit provider version pinning to ensure reproducible builds
• •Implement snapshot-test-rollback strategy for metadata database migration
• •Test DAG imports and business-critical workflows in CI before production deployment
