if you don't have subscroption license, you need to enable the nosubscription repository , and simply do the update online.Hi, sorry for the "stupid" question. When you write that the upgrade to the 7.2 release can be done by gui do you mean that it is possible to perform it using the iso without subscription turned on? Just wondering because I installed 7 days ago a 3 node 7.1.2 cluster that I was tuning and I would like to upgrade to the last release to continue my tests.
Kind regards

(you can configure it though the gui too)
