Run Through Fedora 6 Upgrade Process

[joncameron]

Description

Migration needs to be retested with newer versions of the tooling and Fedora 6.5. Follow the instructions for migrating Fedora 4 -> 6 (https://wiki.lyrasis.org/display/FEDORA6x/Migrate+to+Fedora+6#MigratetoFedora6-TheFedora4%E2%86%926MigrationPath) while making adjustments to the upgrade utils based upon https://gist.github.com/cjcolvar/39f1290323373499bb86de0981ba6f27 . Further changes to the tooling might be necessary.

Be sure to retain data in Fedora 4 separately from Fedora 6 so that we can run the migration multiple times as needed.

Done Looks Like

• Fedora 6.5 setup to run alongside Fedora 4 on avalon-dev. Or keep Fedora 4 as a dump that could be resurrected / re-migrated.
• Migration run on avalon-dev data
• Draft migration instructions for Avalon wiki

So far, Chris has done the migration on avalon-dev data from a dump. Getting ready to do migration on avalon-dev.

Draft instructions I used for avalon-dev (containerized). These will need to be refined and the modified upgrade-utils will need to be made available or changes pushed upstream and released. I attempted to use these instructions on mco-staging (non-containerized) but the export failed when attempting to export the root node. Therefore, these instructions may only work for repositories of small enough sizes.

In Fedora 4 container:
podman exec -it avalon_core-devel /bin/bash
cd /tmp
mkdir fc4_to_fc6
cd fc4_to_fc6

Updates needed to the instructions above: Use version 1.2.0 for the import-export tool and modify the command to drop --versions and add --membership.
