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?
To migrate your existing virtual server images to Oracle Cloud Infrastructure (OCI), you should export your current image in the VMDK format and copy it to an Object Storage bucket. Then, import it as a custom image and select native mode to ensure the best possible performance. VMDK is a widely supported format and importing it in native mode will allow the virtual machine to interact directly with OCI hardware, which ensures optimal performance. Emulated mode, on the other hand, might be useful for compatibility with legacy drivers but can lead to performance issues.
Option D specifies the QCOW2 image format. QCOW2 is a virtual disk image format that is supported by OCI. However, if you select emulated mode when importing a QCOW2 image, the virtual machine will not be able to interact directly with the OCI hardware, which can result in performance degradation.
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.
Option D! Option B is importing using native mode, and that CentOs version is not compliance yet.
