# Seamless Source/Target Switchover

KubeStash supports seamless source/target role switching with minimal performance impact. Switching primary and secondary roles between DC and DR is a coordinated act across the data layer, the control plane, and the traffic plane. KubeDB owns intra-cluster failover for supported database engines. KubeStash provides the verified, restore-tested data layer underneath: `BackupVerifier` proves the DR copy is restorable before the switch, and a `RestoreSession` can promote DR data on demand. The result is a smooth, scripted switchover with minimal performance impact on either side.
