7. To track the progress of the network extension, go to the Recent Tasks window, click the All tab, and ensure you are
viewing All Users’ Tasks. Click on More Tasks to open the Task Console. The network extension is done when the
Extend Network task status is Completed.
Migrating a Virtual Machine to vCloud Air
To migrate a virtual machine you must have a secure connection maintained by the Hybrid Cloud Gateway. You can
speed up the migration if you use a stretched network, Hybrid Networking Premium, WAN Optimization, a Direct
Connection, or a combination of these features.
Understanding Replication-Based Migration
Hybrid Cloud Manager enables bidirectional migration: on premises to the cloud, or from the cloud to back to on=-
premise datacenter. Hybrid Cloud Manager uses vSphere Replication during the migration process. vSphere Replication
is integrated in the Hybrid Cloud Gateway virtual appliance, so you don’t have to worry about installing or maintaining
vSphere Replication.
Note: Hybrid Cloud Manager uses vSphere Replication in the ESX hypervisor and Cloud Gateway. The
DRaaS replication appliance is not used.
Note: A migration cannot be cancelled once it is initiated.
To reduce downtime, the source VM remains online during the replication and is bootstrapped on the destination ESX
host once replication completes. The original virtual machine is copied to the “Migrated VMs” folder in the vSphere
Templates view to enable recovery.
A migration request from Hybrid Cloud Manager triggers the following actions:
1. Hybrid Cloud Manager uses vSphere Replication to create replication groups within the on-premises ESXi host
running the VM.
2. vSphere Replication begins a full synchronization transfer into a vCloud Air virtual datacenter (vDC).
The time it takes to replicate is a function of the size of the VM.
3. When full synchronization completes, a delta synchronization occurs.
4. When the delta synchronization is complete, Hybrid Cloud Manager executes a switchover. You can choose to start
immediately or delay the switchover until a specific time.
