Answer: Optimize network and configuration. 1. Prioritize 10 Gbps networks for migration (If the management network interface is 1 Gbps, switch to overlay network interface or storage network interface for migration). 2. Enable the compressed transfer feature. (Select during migration. Minimal CPU must be consumed, but the efficiency can be improved). 3. Limit concurrent tasks (Up to 2 VMs can be migrated at the same time per cluster to prevent occupying bandwidth fully). 4. Migrate VMs during off-peak hours (which reduces source VM write operations to minimize dirty data sync).
