Description Jose Luis Franco 2020-09-02 12:48:59 UTC

Description of problem:

It is highly recommended to execute the leapp preupgrade check before running leapp, as it is mentioned in the official documentation to upgrade from RHEL7 to RHEL8: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/upgrading_from_rhel_7_to_rhel_8/index#reviewing-the-pre-upgrade-report_upgrading-from-rhel-7-to-rhel-8

Therefore, we should encourage the OSP users to do the same before upgrading their Undercloud. It is the best way to catch issues with the leapp requirements, as the preupgrade does not modify the system.

The syntax would be something like:

sudo leapp preupgrade --debug --enablerepo rhel-8-for-x86_64-baseos-eus-rpms --enablerepo rhel-8-for-x86_64-appstream-eus-rpms --enablerepo fast-datapath-for-rhel-8-x86_64-rpms --enablerepo ansible-2.9-for-rhel-8-x86_64-rpms
