Hi @crossan007
We did fork the original script to the AntennaPod organisation: GitHub - AntennaPod/migration-scripts: Migrate data from the Podcast Addict database to AntennaPod
As per Monthly community call! - #77 by keunes, @Eliot would update their changes a bit (the PR you linked to @crossan007) and submit a PR against this forked repo, when they find the time.
