Migrate from S3-Uploads to MediaCloud
It would be nice to offer a way to migrate from S3-Uploads to MediaCloud, since it's not a really easy "drap & drop" step for existing steps. (I assume metadata has to be updated, path in articles too etc...)
What do you think ?
Humanmade S3-Uploads or Offload Media?
So I looked into it and S3-Uploads doesn't store any metadata. It just blindly assumes that all of the media in your library is on S3 and that all of the related thumbnails and images sizes are there too. The only piece of data is the GUID of the post in the database is the S3 URL, but that's not enough for Media Cloud to automatically migrate it like it can with Offload Media.
So no automated migration is possible then ? ok thanks for looking.
Version 3.1.5 has a new command line tool to do S3 Uploads Migration, but it's a "best guess" kind of migration, though it has worked in our testing.

It has to make quite a few assumptions just because of the nature of how that plugin works.
