AEP's Snowflake Batch Format Change: What Engineering Teams Need to Do Before June Ends
AEP changed its Snowflake Batch destination table structure in March 2026, and the legacy column-per-audience format is deprecated at end of June 2026. Data engineering teams running AEP → Snowflake Batch activation pipelines need to migrate to the V2_ table structure before the deadline or production pipelines break. This was a silent product change documented in ExperienceLeague rather than notified by email — many teams haven't seen it. Additional constraints include a 7-day TTL on exported data and Azure Private Link incompatibility that compound the migration planning.
