Transparent Migration from Datastore to Firestore
Summary: Describes a transparent, automatic zero‑downtime migration engine that moved >1M Google Datastore databases from Megastore to Spanner-backed Firestore while preserving data integrity and customer continuity. Covers multi-year planning, operational principles (no downtime, no DB left behind, explicit customer consent for regressions) and the practical engineering solutions used to execute the three-year rollout at cloud scale.
