Copy dashboards, queries AND charts from develop instance to production instance

Hi guys.
Please excuse me if i’m pretty rude: i’m trying to understand how to do something that could be very simple without being able to do it.
All i need is in the title:
i read several topics about - more or less - the same problem, but nothing that include also charts in the “backup”.
No problems with export of the results, as it’s not a feature we need: simply we have to build about 100 queries with its own charts (and we’ll do it “at home”), then move all queries and charts to a different server into a redash installation where other user have their own dashboards, query, and charts.
Thanks for the support.
