--- upgrade: - | The default network for the ctlplane changed from 192.0.2.0/24 to 192.168.24.0/24. All references to the ctlplane network in the templates have been updated to reflect this change. When upgrading from a previous release, if the default network was used for the ctlplane (192.0.2.0/24), then it is necessary to provide as input, via environment file, the correct setting for all the parameters that previously defaulted to 192.0.2.x and now default to 192.168.24.x; there is an environment file which could be used on upgrade `environments/updates/update-from-192_0_2-subnet.yaml` to cover a simple scenario but it won't be enough for scenarios using an external load balancer, Contrail or Cisto N1KV. Follows a list of params to be provided on upgrade. From contrail-net.yaml: EC2MetadataIp, ControlPlaneDefaultRoute From external-loadbalancer-vip-v6.yaml: ControlFixedIPs From external-loadbalancer-vip.yaml: ControlFixedIPs From network-environment.yaml: EC2MetadataIp, ControlPlaneDefaultRoute From neutron-ml2-cisco-n1kv.yaml: N1000vVSMIP, N1000vMgmtGatewayIP From contrail-vrouter.yaml: ContrailVrouterGateway
