I have an export of media from another (older) version of umbraco that I want to import into a new (v13) version of Umbraco. The media is already stored in Azure Blob storage, so I don't want to physically move the files.. I just want to recreated the media in the new instance, ensuring that the URLs remain the same. I'm attempting to iterate through the items now, and it seems to save successfully, but then requests in the backoffice timeout after trying to load the media section. Can anyone point me in the right direction?
