https://sharma-hina.medium.com/successfully-upgrade-openshift-cluster-on-a-disconnected-environment-with-troubleshooting-guide-e5ad32541d7a

Usage

• $ node app [currentversion] [targetversion]

  • currentversion: Current OCP version(before upgrade)
  • targetversion: Target OCP version(after upgrade)

• Ex. If your OCP is version 4.4.6, and you want to upgrade to 4.6.4, then you would try this command:

  • $ node app 4.4.6 4.6.4

• Result would be displayed like this:

  • 4.4.6 -> 4.4.13 -> 4.5.16 -> 4.6.4

  • This means you should ...

    • (1) upgrade from 4.4.6 to 4.4.13 first,

    • (2) next, upgrade from 4.4.13 to 4.5.16,

    • (3) and, upgrade from 4.5.16 to 4.6.4.

    • Those all 3 upgrades are supposed to be possible(= supported, based on release.txt).
