summary
Claims a production migration of 20 TB in under an hour from AKS to GKE using Kubernetes plus Vitess, performed by taking backups to GCS, restoring shards (≈250 GB targets) and reparenting masters. Uses public Helm charts, nginx ingress, cert‑manager, external‑dns, and dedicated node pools with preemptible nodes to cut cost. Leverages Vitess features: VTGate/VTTablet topology, asynchronous replication and Vitess messages as a MySQL-backed queue. Migration completes successfully with minimal downtime.
