One server for 2 Discourse communities?

Thanks! This is still aligned with current supported multisite practice - nothing here conflicts with how Discourse multisite works today.

Yes, the same steps apply when converting an existing monosite install to multisite: a monosite is effectively a multisite with a single default site. You can enable DISCOURSE_MULTISITE, add multisite.yml (including the existing site), rebuild once, and run rails multisite:migrate in place.

If there’s anything here that no longer reflects best practice, I’m very happy to update the runbook - the goal is a linear, supported checklist that avoids trial-and-error.
