Exceptions

Exception	Condition
TimeoutException	Retry is exhausted.
InvalidOperationException	Invalid operation - If action called on stateless service. - If no active secondary replica exists - If not enough nodes available for action
FabricException	FabricErrorCode.AlreadyPrimaryReplica - If Primary replica for selected partition already exist on new node FabricErrorCode.AlreadySecondaryReplica - If active Secondary replica for selected partition already exist on new node FabricErrorCode.InvalidReplicaStateForReplicaOperation - If Current Secondary node is not a secondary replica FabricErrorCode.ConstraintNotSatisfied - If the constraints for the new location of the replica would prohibit the move

Remarks

This API overload randomly selects current secondary node for random secondary replica of the selected partition and new secondary node for replica movement This selected replica will be moved to new node location from current node location. This API is safe i.e. it will not cause quorum or data loss by itself unless additional faults or failures happen at the same time.
