Keras 3 .keras save format: preserving optimizer state during zero‑downtime migration Goal: migrate a small inference service from Keras 2 HDF5 checkpoints to the Keras 3 .keras zip format without taking the service offline. Constraints: the migration must keep the optimizer state and training history intact so that fine‑tuning can resume immediately after t
