Hey,
If you want to move the replicated VM to a replica host, you will need to perform planned migration. You can find detailed information here: https://learn.microsoft.com/en-us/windows-server/virtualization/hyper-v/manage/set-up-hyper-v-replica
As for StarWind VSAN and Windows Server, VSAN can be used as a shared storage for Failover Cluster. VSAN HA LUNs are replicated between the LUNs, while Failover Cluster will handle failover and Live Migration. You don't need to use Hyper-V Replica in this config. https://www.starwindsoftware.com/resource-library/starwind-virtual-san-for-hyper-v-2-node-hyperconverged-scenario-with-windows-server-2016/
As for Recovery Points, you can use checkpoints with your HA VMs. https://learn.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/checkpoints
