oc has commands like oc adm upgrade, oc adm upgrade recommend, and oc adm upgrade status that read in cluster state (predominately ClusterVersion status for those three, although recommend also consumes alerts and status consumes alerts and a number of additional Kube-API resources like ClusterOperators as well) and print a report. You cannot run those directly on a must-gather, because oc doesn't understand how to talk to must-gathers. You cannot run those with omc today, because omc doesn't support any adm sub-commands yet. This issue tracks omc growing support for those read-only adm subcommands, although I'm not clear on if/how implementation would work.
