We sometimes get asked about how to make use of offline repositories that are not Satellite. While this is not formally supported as we have no way of knowing the correct way to configure the repository in this situation, we can provide some guidance for how it could be done and provide examples for how to configure the upgrade process with some assumptions. Doing so would make it easier for customers and our field folks to have a better understanding of what to do.

For example, setting up a mirror can be done with https://access.redhat.com/solutions/7019225

When setting up the mirror, it must have both RHEL 8.4 and RHEL 9.2 content.

Assuming that the mirror's repo configuration is provided in a local file on the server, the system_upgrade.yaml would look something like:

parameter_defaults:
  LeappRepoInitCommand: |
    rm -f /etc/yum.repos.d/*
    cp /home/stack/rhosp17_rhel9.repo /etc/yum.repos.d/
    yum clean all
    yum repolist 

We may need to do additional adjustment for multi-RHEL scenarios, etc.

I expect this to be documented as a knowledgebase article and then linked from the main docs.
