When you restore a VM from a different hypervisor to create an Oracle Cloud Infrastructure instance, the conversion process includes operations to copy configuration settings and instance data.
The conversion process includes the following stages:
Create a temporary VMDK file on the proxy.
Upload the VMDK file to OCI object storage.
Import the VMDK as a custom image.
Create a temporary instance with a boot volume.
The size of the boot volume matches the shape that was selected for the target instance.
Delete the temporary instance while retaining the boot volume.
Create empty data volumes.
Attach all volumes to the VSA proxy.
Write data to the volumes.
Detach the volumes from the proxy.
Launch the new instance from the boot volume.
Attach the data volumes.
Reboot the instance.
