Cannot load existing uploads, artifacts after restoring

Reproduction steps:

• Install new gitlab helm chart
• Restore the backup taken from previous omnibus installation which has local uploads (instead of object storage)
• Old uploads (avatars etc) & artifacts fail to download
• New uploads (after restore) are shown correctly

Further more, I checked that, incase of old uploads it's loading the data from local (instead of object storage). However, for new uploads, it loads correctly from object storage.

Is there any migration missing to change existing uploads to object storage?
