I have to move my Discourse installation from one server to a new one. I have full access to both servers via SSH Port 22 and forwarded ports 80, I can log-in to the old installation and create a backup.
However, mail does no longer work, so I cannot download the backup because I do not have access to the link sent to my old email. And I cannot change the email address, because the change has to be confirmed from my old email.
Would it be possible to copy the complete docker volume, and where do I find it?
