The parent issue RHELC-1509 has the label that triggered autocreation of this subtask to track the relative story point estimation for the integration test part of the issue.

The parent issue description at the time of creation of this issue was:
After at least one convert2rhel downstream version warned customers that using env vars is deprecated (RHELC-1508), we can remove the possibility to use env vars to alter convert2rhel behavior altogether. This is a breaking change so we should bump up the major version.
