I still don’t see how GlobalSetting.use_s3? is ever true. I have GlobalSetting.use_s3, but not with a ? and I don’t see how seeting those ENV vars sets GlobalSetting.use_s3?. Maybe that’s supposed to happen somewhere that I don’t know about or understand, but I removed the ? in order to be able to run the script at all.
So I removed the ? and the dry run looked promising and I ran it for real. It took a couple days (70GB files and a badly configured network adapter) and then it failed like:

It’s probably coincidence that it’s the same error as Trouble with `discourse remap` remapping `topic_links url` (it is a different site).
