Do you want to migrate your VMware and Red Hat Enterprise Linux to Oracle VM and Oracle Linux?
If so, check out the hands-on lab that walks you through best practices for migrating an existing Oracle Database workload from VMware to Oracle VM. This lab also walks you through migrating to Oracle Linux from a Red Hat Enterprise Linux 6 guest exported from VMware by downloading Oracle's Unbreakable Enterprise Kernel.
By performing the steps in this lab, you will obtain a fully supported and certified configuration for Oracle Database (whereas on VMware, Oracle Database is only supported, not certified).
