What happens in TMM if a video file is renamed?

Hi all. I let Sonarr/Radarr automate the file renaming of all my media (and have renaming disabled in TMM). What happens in TMM if Sonar/Radarr upgrades one of my existing scraped videos and the filename changes?

E.g.

Before:
-Movie Name (Year)
--Movie Name (Year) - [HDTV-1080p][HDR][DTS][x264].mkv
--Movie Name (Year) - [HDTV-1080p][HDR][DTS][x264].nfo
--Movie Name (Year) - [HDTV-1080p][HDR][DTS][x264]-fanart.jpg
--Movie Name (Year) - [HDTV-1080p][HDR][DTS][x264]-poster.jpg

After:
-Movie Name (Year)
--Movie Name (Year) - [Bluray-2160p][HDR][DTS][x264].mkv
--Movie Name (Year) - [HDTV-1080p][HDR][DTS][x264].nfo
--Movie Name (Year) - [HDTV-1080p][HDR][DTS][x264]-fanart.jpg
--Movie Name (Year) - [HDTV-1080p][HDR][DTS][x264]-poster.jpg

Does TMM have to rescrape again? Will there be duplicate metadata files? Does it cleanup/rename existing files?

Thanks in advance!
