My question is how can I preserve the name of the documents on the disk (not in the metadata, it’s the same) when migrating from omeka classic to omeka S?
Thanks in advance if you have any ideas.
so i can just copy all the pdf/jpg files from omeka classic files storage to omeka S files storage, and then export tables files and media from omeka classic to omeka S tables ?
Yes, copy the files in files/original.
But the hard part is the database. You have to take the filename from the table files in Omeka Classic and copy it without extension into the table media (storage_id) of omeka s. Take care of the media id of course, because they probably have been changed between omeka classic and omeka s. So export id and storage id, map them with classic filenames, then import it in the table media.
Then eventually recreate the derivative with module EasyAdmin.
