Is it worth digging through downloader and Couchpotato logs to get back “unrecoverable” filename information?

I’m at least 7 years late migrating to Radarr and for a long time I used “Title [year].mkv” naming convention. Every time I consider the move, I debate scouring old logs for original filenames prior to initial import then I get caught up in other tasks before forgetting about it and starting the cycle over again.

Most importantly, I want to move to a management tool that’s still supported, and ideally I’d like to clean up the qualities/encoding (and possibly shrink the overall size without losing more quality or spending the time/electricty to re-encode)

Edit: Mostly looking for source info, I don’t care about release group tags. Mediainfo can get a ton of data but there are quality pieces that I’m not sure are important.
