Migrating Discourse

How to migrate Discourse (the official way)

1. update discourse and the db to the latest version on the old server
2. add a global notice about the move
3. create and download a new backup
4. bootstrap a new db and app instance on the new server (disable S3)
5. upload the backup
6. restore backup
7. enable S3 and rebuild the app container.

(the cursed way) copy the bind volumes and wing it.
