Hi @<1577468611524562944:profile|MagnificentBear85> , what you need to check is the mongodb component, which contains all of the administrative data (and metadata)
Fileserver only contains uploaded artifacts and models usually (so at most if you have any configuration issue you'll have links to artifacts that will be broken) - what you're seeing seems to indicate the mongodb data was lost, misplaced or there was some issue with the migration when moving to the new machine. In general you should have moved the entire data folder containing the mongodb and elasticsearch data
Thanks, I solved it. It was a very weird error in putting back the backup
