Hi,
Is there any mechanism (or query) that could easily take everyone who currently has enabled Theme ID X and swap them to Theme ID Y.
I currently have Theme X which is a bunch of messy components and want to replace it with an identical Theme Y which will be linked to GitHub. But I don’t want everyone who has chosen Theme X to notice any difference (i.e. I can’t just delete it and tell them all to pick Y).
Any help would be appreciated 
I guess I could import the GitHub theme as a new component and make it the only component of Theme X. (at least I think that would work?) But that doesn’t seem the most elegant solution.
This should do it, but you should make a backup first.
cd /var/discourse
./launcher enter app
old_id=2
new_id=21
UserOption.where(theme_ids: [old_id]).update_all(theme_ids: [new_id])
Great, cheers!
