Disclosed are various examples for top-of-rack (TOR) switch replacement in hyper-converged computing environments. A bring-up network configuration is applied to a network switch to install the network switch in a rack. An active workload within the rack is analyzed to identify a workload network configuration for the active workload. The active workload is reassigned to the network switch from a faulty network switch. The network switch is configured based on the workload network configuration for the active workload.
