Can I upgrade directly from 15.5 to 15.8.1?

Issue/Introduction

we downloaded DVD0000000001009.iso as directed

we are running 15.5.1 and when I look at the install packages:

[ /opt/clarity/UPGRADE_15.8.1/install-packages ]
someUser > ls -l
total 4
drwxrwxr-x. 2 clarity clarity   52 Jun 19 12:22 15.7.0
drwxrwxr-x. 2 clarity clarity   52 Jun 19 12:57 15.7.1
drwxrwxr-x. 2 clarity clarity   52 Jun 19 13:44 15.8.0
drwxrwxr-x. 4 clarity clarity 4096 Jul 13 18:38 15.8.1

it seems as if a few directories are missing to get from 15.5 to 15.8 so will this media work?

please advise

Resolution

The upgrade to 15.8.1 is only certified for '15.6.1,15.7.0,15.7.1,15.8.0' release versions.

To get from 15.5.x to 15.8.1, you'll need to first go to 15.6.1, and then upgrade to 15.8.1
