Live migration in HCX, one VM per move: the running machine is carried to the paired site over vMotion together with its memory and execution state, keeping its IP and MAC addresses, so users see no outage. Inter-site bandwidth and latency govern how long it takes.

Each book explains HCX vMotion in context, with comparison tables and the common traps.
Terms in this definition
- Live migration
Moving a Hyper-V virtual machine to a different host while it keeps running, without users noticing an outage.
- LSDOU
The sequence in which Group Policy is processed: the local policy first, followed by site, domain and organisational unit policies. The nearest, last-processed setting takes effect unless Enforced or Block Inheritance alters that.
- OVER
Gives a T-SQL window function its window: PARTITION BY, ORDER BY and, if wanted, a ROWS or RANGE frame. Rankings and running totals can then be worked out while every row is kept.
- vMotion
Moves a running VM to another host with no downtime; its storage counterpart, Storage vMotion, relocates the files between datastores instead.
- State
A parameter in OAuth that carries custom data through the authorisation flow and back, as with the "Support state parameter" option in APIM.
- Govern
The part of the Cloud Adoption Framework concerned with keeping cloud use under control by setting guardrails made of policies, procedures and tools. It runs continuously across the estate alongside Secure and Manage.

- Mobility Agent
Removing this host object breaks HCX vMotion, Cold and Replication Assisted vMotion migrations, which need it. The HCX-IX appliance places it in vCenter, and whatever resources it shows do not represent actual consumption.
- 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.
