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.
