Yes, indeed, if you're looking to scale up to handle high concurrent user loads, scaling out horizontally is your best bet. We've got a client right now serving 700+ connections at the moment, and they're on four separate NodeBB instances. It's probably too much for what they need, but it's always nice to have more capacity than needed in case of spikes, etc.
I've been working on migrating an existing forum to nodebb and have the last steps left.
I did a working test import and everything looks good.
We are running NodeBB 0.6.1 on Mongo
Now I would like to empty the database from users and discussions, while keeping all the settings I've made. The ACP is not an option, as there are quite a lot of users and discussions.
