You are in the process of migrating several legacy applications from on-premises to Oracle Cloud Infrastructure (OCI). The current servers are already virtualized. However, you notice that the version of CentOS currently running does not align with any of the Oracle-provided compute images.
How would you migrate your existing virtual server images to OCI?

A. Export your current image in the VDI format and copy to an Object Storage bucket. Import it as a custom image. Select native mode to ensure the best possible performance.

B. Export your current image in the VMDK format and copy to an Object Storage bucket. Import it as a custom image. Select native mode to ensure the best possible performance.

C. Export your current image in the QED format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers.

D. Export your current image in the QCOW2 format and copy to an Object Storage bucket. Import it as a custom image. Select emulated mode to ensure compatibility with legacy drivers.

Solution: D
Explanation: Emulation Mode: Ideal for virtual machines lacking support for paravirtualized drivers, particularly those created externally from older on-premise physical or virtual machines
