• Embedding Model Upgrade in Production: Zero-Downtime Migration with Dual Writes, Blue-Green Vector Indexes, and Atomic Alias Switching

  Upgrading an embedding model is more than swapping a model name. This post breaks down production migration strategies—dual writes, background re-embedding, blue-green vector indexes, atomic alias switching, rollback windows, and incremental updates—to avoid recall drift and service disruption.
