You are in the process of migrating several legacy applications from on-premises to Oracle Cloud Infrastructure (OCI). The current servers are 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? 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. ... You have an instance running in Oracle Cloud Infrastructure (OCI) that cannot be live-migrated during an infrastructure maintenance event.
