Can I get some advice on this? Can I just copy /var/discourse/ to the new droplet?

No you just take a backup, do the official guide install in 30 minutes, switch DNS, restore backup.

I take it you mean the backup from the discourse-menus. The problem is I can’t start discourse… 😕 Because of all the problems herein detailed.

You didn’t made a backup before upgrading the server?

😑
I. Am. Stupid.
Well, this is first time this has happened to me. I have a backup on Dec 20th. Now I know in the future that anything you do, backup first.

Considering your forum is down for a day or so, maybe getting back up with this backup isn’t the worst idea.
