@DownPW Seems fine.

@cagatay ok. You should use a copy of the production database or a completely new one. Never share a database between two instances of NodeBB.

@cagatay JS will work fine - no changes there, and there are no plans to drop support for jQuery. More of an issue is the CSS - for which there are quite a few breaking changes. Keep an eye on sudonix.dev (my development site) where you can see progress in relation to how I am tackling the compatibility issues.
