Workloads can be migrated bi-directionally between data centers using various VMware HCX migration technologies. VMware HCX Migration Types Virtual Machines can be moved to and from VMware HCX-enabled data centers using multiple migration technologies. Understanding VMware HCX Bulk MigrationBulk migration uses the host-based replication to move a virtual machine between HCX data centers. Understanding VMware HCX vMotion and Cold MigrationThe VMware HCX Interconnect integrates with ESXi to perform migrations based on the vMotion protocol for live powered on virtual machines, and with VMware NFC for cold migrations on powered off virtual machines. Understanding VMware HCX Replication Assisted vMotionVMware HCX Replication Assisted vMotion (RAV) uses the HCX Interconnect appliance along with replication and vMotion technologies to provide large scale, parallel migrations with zero downtime. Understanding VMware HCX OS Assisted MigrationThe HCX OS Assisted Migration service uses the Sentinel software that is installed on Linux- or Windows-based guest virtual machines to assist with communication and replication from their environment to a VMware vSphere SDDC. Migrating Virtual Machines with HCXThrough the HCX Migration interface, you can configure multiple virtual machine migrations, including reverse migrations. Migrating Virtual Machines with Mobility GroupsMobility Groups is an HCX Enterprise License feature that supports assembling one or more virtual machines into logical sets, for execution and monitoring of migrations as a group. Additional Migration SettingsThe VMware HCX migration interface provides a set of options that can be used to tailor the behaviors and conditions of the Virtual Machine before or after the migration operation.
