VMware Hybrid Cloud Extension (HCX) abstracts on-premises versus cloud notions and presents capabilities to virtual machines (VMs) as a continuous hybrid cloud.
There are four different HCX migration types, which are briefly summarized below:
Figure : HCX Migration Types
Each of the four methods referenced above can be used to migrate standalone Oracle workloads, per SLA requirements.
HCX Replication-Assisted vMotion® (RAV) is a new migration method that combines the benefits of both HCX bulk migration (i.e., parallel operations, resiliency, and scheduling) and HCX vMotion (i.e., zero downtime VM-state migration).
Migration begins with the replication of the VM's disks. As is true for bulk migration, VMs can be moved in parallel with the switchover configurable on a schedule.
During the RAV switchover phase, vMotion is engaged for migrating the disk delta data and VM state.
