After changing internalJoinSubnet,internalTransitSwitchSubnet, on day2 and do live migration.  ovnkube node pod crashed

network part as below the service cidr has same subnet with the ovn default internalTransitSwitchSubnet

    clusterNetwork:
    - cidr: 100.64.0.0/15
      hostPrefix: 23
    serviceNetwork:
    - 100.88.0.0/16

and then:

oc patch network.operator.openshift.io cluster --type='merge' -p='{"spec":{"defaultNetwork":{"ovnKubernetesConfig":{"ipv4":{"internalJoinSubnet": "100.82.0.0/16"}}}}}'
oc patch network.operator.openshift.io cluster --type='merge' -p='{"spec":{"defaultNetwork":{"ovnKubernetesConfig":{"ipv4":{"internalTransitSwitchSubnet": "100.69.0.0/16"}}}}}'

with error:
