Metadata not updated

[Tsch3ns 19]

Hello,

after migrating my database from DS918 to DS425 and copying all movies to the 425, lots (if not all) movies miss metadata (pictures of actors), see attachment. I already tried to update the metadata of the whole library without success. I have to update each movie individually in order to get the missing data. Whats wrong here?

Emby Premiere Server 4.9.5.0

Hi, how exactly did you migrate?

After installing Emby on the new synology I moved the databases folder "embyserver-backup-full" and the folder from the latest backup folder from the old synology to the new one.

/volume1/@appdata/EmbyServer

Then I copied all files, same folder structure as before, from the old synology to the new one. >1200 movies, more than 6 TB.

Jens
