the supported method is to restore it from a backup generated by RoonServer before the upgrade (remember the pre-upgrade recommendations that most of us ignored - disable storage locations & create a backup ?); if you don’t have a backup, short answer is you can’t & long answer is maybe (try instructions linked below , after you carefully identify the directory / share path to use; edit: if you need help with that, share screenshots of your docker-compose yaml & Roon relevant shares as seen in FileStation) ..
