Avoids tromboning on networks extended by HCX: migrated VMs route via the destination site instead of back through the gateway at the source. This Network Extension option applies automatically to VMs moved by Bulk migration, whereas vMotion and RAV leave VMs on the source gateway until someone reconfigures them.
Also called MON.

Terms in this definition
- Virtual machines
Infrastructure-as-a-service compute giving complete control of the operating system, making it a fit for lift-and-shift moves and for software relying on OS-level pieces like COM.
- Veeam Infrastructure Appliance
A hardened, minimal Linux (JeOS) ISO for running backup proxies, repositories and hardened repositories. It connects to a backup server but does not host one.
- Destination site
Receives VMs and networks extended from its VCF Operations HCX partner. Because pairing works in one direction, any operation (service mesh, network extension, migration, or even moving VMs back) is initiated at the source end.
- Network Extension
Migrated VMs keep their IP and MAC addresses because this VCF Operations HCX service bridges their networks (VLAN-tagged distributed port groups, NSX segments or NSX VPC subnets) to the remote site through a pair of appliances. Unless Mobility Optimized Networking is used, the default gateway stays at the source.
- Bulk migration
Not a zero-downtime option: with this VCF Operations HCX method, a live VM is copied through host-based replication and then, at an optionally scheduled switchover, the original is shut down, final changes are synchronised and the replica started, costing roughly a reboot's worth of outage.
- vMotion
Moves a running VM to another host with no downtime; its storage counterpart, Storage vMotion, relocates the files between datastores instead.
- RAV
Replication Assisted vMotion: unlike HCX vMotion, which moves one VM at a time, this VCF Operations HCX migration type replicates large numbers of VMs in parallel and keeps them in sync until a scheduled switchover, when each moves live through a final delta vMotion. It is the choice for zero-downtime migration of big waves.
