## AI overview

The article explains how teams can make zero data loss in compliance platform migrations auditable. It argues that row counts alone are insufficient: teams must verify that required records and fields arrive, relationships survive, and the data retains its meaning. It also recommends treating field mapping as a deliberate artifact with destinations, transformation rules, ownership, and validation methods.
