Options
- ARun a Recovery Plan planned failover.
- BUse Cross-Cluster Live Migration.
- CPerform a Nutanix Move migration plan.
- DMigrate Asynchronous Protection Domains

Why each option
Cross-Cluster Live Migration in Nutanix AHV allows VMs to be moved between clusters managed by different Prism Central instances with minimal downtime, and it supports pass-through GPU VMs. This is the appropriate method when live migration across independently managed clusters is required.
A Recovery Plan planned failover is designed for disaster recovery scenarios using Protection Policy replication, not for live pre-maintenance migration of GPU pass-through VMs.
Cross-Cluster Live Migration enables seamless VM movement between AHV clusters - including those with GPU pass-through - without requiring shared Prism Central management, making it suitable for the two-independent-PC scenario described. It performs the migration with minimal downtime by leveraging live migration techniques across cluster boundaries, which is ideal for pre-maintenance workload evacuation.
Nutanix Move is an agentless migration tool for moving workloads from third-party hypervisors to AHV, not for live migrating running AHV VMs between clusters.
Asynchronous Protection Domain migration incurs downtime due to the snapshot-and-restore process and is not a live migration method for minimizing service interruption.
