As long as I’ve been on Pantheon, I’ve never run into this question, but now I have. Normally I’d change the max upload settings in php.ini to increase file upload size beyond 100MB, but I don’t know how to do that in the locked-down php.ini environment here. How do I do it?
You can’t make that change to be able to upload. You can transfer a file larger than 100mb over sftp. Take a look at https://pantheon.io/docs/platform-considerations/#large-files
Thanks for the link. I had forgotten about that one, and apparently I didn’t pick the right search query to find it.
