Support for the change in address space of the service fabric cluster VNet.
Sometime we need to move the existing SF cluster to new address space (say because of overlapping for the future VNets). VMs and Scalesets can be moved to new subnets without much trouble. (add another address space to their current Vnet and create their new subnets in that address space.) However, the Service Fabric Cluster cannot be moved to another address space as the cluster manifest is created with the cluster to point to the scaleset IPs and cannot be changed successfully. Therefore, the cluster has to be redeployed in order to change address ranges, and so all the services and their configuration.
