Migrate existing artwork into media folders?

[Tracenji]

i recently turned on "Save artwork into media folders" on one of my libraries and it works great for new shows and episodes
but existing shows and episodes artwork is till saved inside Jellyfin, not the media folders

is there a way to migrate the existing media artwork over to being stored in media folders without changing the current images?

Negatory. You would need to rescan and "replace all metadata" and check "replace all images" on existing items.

Only trickplays can be migrated.
