I am trying to upgrade from Oracle Linux 6 to Oracle Linux 7. I am following the procedure for an in-place upgrade outlined in the document 4.2 Performing an Inplace Upgrade. The process is also described in Oracle Linux: Limited Support For In-Place OL6 Upgrade To OL7 (Doc ID 1968994.1). I am trying to figure out why when I run the preupg utility during Step 4 as to why my the generated results show no success or failures and in the text output it shows 'notapplicable' for all of the prerequisite checks. Am I missing something or is this normal?
